I feel your pain on parking tickets Here's one, working off a extension ladder install lights watch meter maid ticket my truck and then by pass the car in front of me ticked cars further down the street, I ran down the street to catch up with her and ask why she did not ticket the car in front of me, she said out of state plates and she didn't want up set them. I said, I working man don't I deserve a break also, she replied I should have paid the meter, I replied I guess I will have to call your boss, went back to work and watched her walk back to that car it, the owner came out of the pizza shop and ask what was going on? she blamed me for him getting this ticked and that I complained about it. The funny part about this (I over heard this because I was on the extension ladder near the pizza shop installing lights), the guy replied, you should have skipped him because he is working here and got me instead and not what your are doing now. I ended up paying both tickets because stood up for me and email him a copy of payment. both together under 50 dollars if paid by certain time.
Loved every video so far Thomas. I am retired now (best timing) but I had 30 years of being audited as a 2 person company, having to have Aviation / European / BSI approvals or the larger companies would not give us any contract work. Finally I worked out that I had enough work anyway, paid on time by the smaller customers, no 60 days chasing payments, not having to "doff my cap" to get the breadcrumbs off the table from larger companies, not having to bend over and get shafted on a regular basis. Once you get your approvals you will then have to contact all your suppliers and ask for their approvals, AND AUDIT THEM.............its never ending and not sure its worth the hassle or cost in time. I think the smaller operator will always have work if you produce the quality of work you have always demonstrated. Just my thoughts, others may think otherwise.
Here in Brighton and Hove Parking Officers are not giving tickets unless you vehicle is parked dangerously, causing an obstruction or parked on Zig Zags. This will change when the lock down comes to an end.
What you've mentioned at the end of the video, the neatness of the wiring in boxes, that just reflects the pride people have in their work. Nothing more, nothing less.
When electricians try to be neat, it makes it impossible to trace individual wires on a problem solving gig. I have tried to tell our younger dudes to put maximum of two zipties per cabinet cell. It is nice if there is some effort, but bundling and tying everything together is a nightmare when you have to solve some designers relay-dream (without documents of course) in a 2 meter wide cabinet with 20 different cells full of stuff. Another ziptie rule I have tried to spread, is that on a renovating projects, you have to cut two old zipties to add one new. There are most likely 20 layers of wires tied one by one on all cable trays and again, removing or tracing one of those is a nightmare. That is why cheap contractors leave all old cabling on the trays and after 30 years of little changes, trays are full and no one knows what could be removed to make room to the latest addition. I just hope that copper prices would go up, so that more electricians would have a reason to scrap all unneeded cables. That little box in the video was bad, but i wasn't that worried about those messy wires, as there was also way more dangerous thing: uninsulated copper sticking from the busbar. Those seem to be after that rcd, but little bit of bad luck and you would have your other hand on the neutral bar of that same circuit..
8:20, I deal with audio installations, in regards to damaging the audio equipment, if there is powered speakers that get turned off at the same time as the dj gear, then a really loud bang will come from the speakers, this sometimes causes the speakers to pop. If the place is getting speakers built in to the building, then it’s best that the power to those turn off before the dj equipment. Sometimes what is done is that a connection to the fire system is connected to the audio processing to mute music and prioritise microphones. But hey, in a real fire, who cares about the DJs equipment. It’s going to burn anyway
That’s just sh!t design on the part of the equipment manufacturer. Any item of electrical or electronic equipment should be able to cope with a loss of mains power without damage being caused. After all, what happens if there is a power cut, or a circuit breaker trips out? In terms of producing audio equipment like a power amplifier (including powered speakers), the extra cost for anti-thump circuitry is almost insignificant compared to the cost of the equipment if it is professional gear.
I came on over from Big Clive's channel and just subscribed. I've really enjoyed your videos I've seen so far, and am looking forward to more down the road. Cheers!
Coming from an audio technicians point of view with that knock off, to stuff like mixers, CDJs, laptops, the vast majority can just have their power yoinked out of nowhere. However, with active speakers or amplified passive speakers, knocking the power is super, super bad. What I recommend from that is to put in a dual-gang socket, one that'll knock out CDJs and digital stuff, the other being regular so that the speakers can at least be turned off properly in the event of a fire. Especially considering that false alarms do happen, pissing off your DJ with a blown speaker or two because some drunk smacked a call point isn't going to end very well
Came over from Big Clive. Nice to see someone in your trade who actually cares about neatness and doing a good job. I seem to not have any luck with hiring contractors.
As "The Essential Crafstman" says keep up the good work. It's an awesome show and I love your and CJRs sensible real world approach to work. As an electrical engineer Down Under, it's great to see solid tradespeople doing solid work, and great to see nee and different techniques and approaches to new and different problems.
“First they ignore you, then they laugh at you, then they fight you, then you win.” What happens when you're the sort of person that thinks outside of the box and has different ideas about life. After this lockdown has ended a lot of people may find they no longer have a job to go back to, if businesses haven’t got the cash to cover their expenses during this period. Many of them may find themselves looking for a different source of income over the traditional job. Always look forward to the next video. Keep up the good work mate!
My fuse board is in a dark cupboard under the sink, they fitted this board and it works really well. A bit of light in a dark cupboard so you can see makes the hell of difference.
just make one out of a worn down sds chisel and put some ø16mm pipe around it,it doesnt hit with the pipe anyways its only there to keep it in place so its plenty strong.
Mc Carly I’ll second this, the last one I fitted was wired like a DOL starter where there are on/off pushbuttons and a 24v interposing relay powered from the fire alarm panel via the aux contact, so when the alarm sounds the relay drops out and so does the contactor. This way a loose connection, damage to a cable or failure of a device is more apparent
If you're worried about corrosion between the stainless and brass stick some tefgel (or similar) on it, it's what we use on boats and does an amazing job of stopping bolts from seizing.
i came heren from Bigclive and i don't regret is at all, i really love your videos! i'm just sitting here bingewatching them and i can onestly say, keep up with what you are doing. i love it and think it teaches people a lot about the work you are doing and that it involves whay more than meets they eye... ps. .english is not first my language
If you want really good toggle bolts then get snaptoggle fixings as these are fantastic and you don’t lose the fixing inside a cavity when the bolt is taken out for any reason. We’ve been using them for years whilst mounting TVs to some walls that we were really worried about, however no problem at all with these.
I had the misfortune to do gigs at a venue with a stage power cutoff driven by a decibel meter, which was a stipulation by the council. If the audience started to sing along it would trip the power :( Just had to refuse to work the venue , and get clients to use different venues.
Thinking about earth rods I have been out to a few domestic properties in rural areas where the tenants have brought a say a new cooker delivered from a store and the engineer won't connect it as the Zs readings on there are higher than they are used to on their multi meter or whatever they are using( doubt it's a multifunction tester) I go out do a zs test and it's perfectly fine well within tolerance. It's a TT system they will give high readings !
Fire alarm should have a contact that is energised when the alarm isn't active. Use that to feed the contractor and feed the supply to the sockets through normally open contacts. Sockets will then cut off when the alarm sounds or if the cable gets damaged.
I was just about to mention galvanic corrosion when you decided to substitute the copper/brass bolt for the stainless one. The fact you knew about it shows how clued up you are. Hopefully the manufacturers will learn by it and provide copper anodized stainless bolts in future. Keep up the good work!
I might have said this before but I always think I'm going to get arrested because I'm staring up at the ceiling of those big box stores scoping out all there cameras, electrical and data cabling
Talking about fire alarm.. does this place have a secondary exit if the first (that stairs) is blocked by fire/smoke ? This would be a complete no-go getting any customers/visitors allowed down there around here.
Have you thought about using your SDS hammer drill on 'Hammer' with a normal chuck to hold the Earth rod,? The other way is to water drill with a hose on a length of 15mm copper.
Thomas, re those LED lights, on your UK OFCOM site, there is a story about an airport, I think in Scotland, where the pilots were complaining that at a certain location near the airport they would loose all radio communications with the tower and air traffic control (not a good thing). After investigation, it was found that the source of the radio blackout was caused by an LED lamp, the type you get from the Asian mail order vendors, the lamp did not conform to ANY type approvals, the lamp was binned, radio service returned to normal.
Have you considered using a post driver for the first several feet of sinking an earth rod? They are not expensive but will take up a bit of room in the van and you will still have to drive that last 2 feet with the hammer. But, you will reduce the risk of finger bashing by 2/3rds... love your stuff. Wish we had ring systems here in the states.
I do like a bit of cable husbandry on my boards that I've fitted, used to take so much pride in the flow of the terminated cables, hope to get my flow back after this lockdown is ended, just emergency calls right now for a third party. be nice to go back to a few and make them pretty for future works.
For safety it quite normal to require the power to hold the switch on, so if the cable gets damaged at any time it will stop the DJ working so will get fixed asap.
kw1984 it’s more about relying on the presence of power that has no back up psi to activate a safety device. Fire alarm out puts almost always work on a energised relay in normal state/ de energise in fire conditions.
Have you got Chapter 8 Chevron markings on the back doors of your van to help with the Parking Ticket situation (think you already have amber LED beacons already)?
Those toggle fittings are the mutts nuts!! In ireland our earth rods and clamps are galvanised steel. Ive never seen one snap here like the ones you showed here.
Someone years ago taught me how to drive a 8ft/2.4m ground rods without a hammer. In my area the ground rod has to be buried. When you dig the hole you fill the it with water and just stab the rod in the ground. You move the rod up and down and the water makes it so the rod almost falls into the ground. You just have to make sure you have water in the hole when you are doing it.
Brass and Stainless Steel together; Galvanic corrosion risk is minimal as they both have similar "Noble Potentials". In my marine experience you would also not directly seal stainless connections as these accelerates corrosion, so boxing it as you do is good. You could also save a lot of washers by using nyloc nuts, I by these along with the nuts and washers from Screwfix in bags.
Feel like on original , ore one of the originals , been highs and lows , Dave's come , gone , come back and gone again ! But through it all you've kept your head high and the videos rolling
Can’t you use stabilising gel to combine 2 metals. And stop the dissiminstion. As 2 metals in contact will cause corrosion. But there has to be a lubrication type gel for combiining metals. 😇. Harry.
A few years ago, my parents moved house. It made economic sense to rewire it (in so far as it wasn't life expired but by the time I'd made the changes that they'd wanted it was quicker and easier to just rewire). I always try to make my panels neat, and this was no exception. Anyway, I did the main part of the house and they had some building work done - the builder insisted on providing their own trades. Once their spark had been at the board, I opened it up and they'd just lashed in the cables. My stuff was neatly dressed, theirs was just run in anywhere - I dread to think what their boards look like.
I’d always have life critical controls or associated controls as normally open so they’ll always fail open rather than stay closed if for whatever reason the controls supply fails 👍 this is obviously dependant on what you want to control and whether it’s better that the thing being controlled needs to carry on functioning during an emergency but a sound system I’d be putting in normally open contactors.
Love the pedant-teasing 'bulbs - sorry, lamps' bit! I believe Mr Savery feels much the same, though he'd be a bit more 'flowery' in his language. I imagine him saying 'every c*** knows what a f***ing bulb is for boll***'s sake' kind of thing.
If the DJ's equipment could be damaged by unexpected loss of power then the DJ hasn't built his equipment stack correctly. Clean power in from the supply company is never guaranteed, so they should have no expectation of it unless it has been previously agreed that the landlord will provide it (eg in a data centre). DJs should have their own power conditioner, and/or UPS (imo).
I'm a DJ - Sudden power loss doesn't cause damage to your equipment at all, it's just people trying to have an opinion on something they don't fully understand. If in the rare case it somehow did, likely the equipment was already faulty and probably shouldn't be in use anyway!
You want to get the earth rods that allow a screw on cap, i thjink they're 1/2 inch ( i dont know the exact name but they screw on and look like a bolt on the top) It allows you to hammer the rod in and if you don't get a good reading you can attach another rod and continue hammering to get deeper as it doesn't ruin the thread and it saves you having to use a hack saw.
I've been with safe contractor for a while. It's an utter nightmare. Especially when I have to prove ongoing health and safety training to my staff... And it's just me 🙄
@ Thomas Nagy, A few points: With respect to driving Earth Stakes, if you have a Hilti hammer drill, get a deep socket that fits on the end of the drill chuck, put it on non-rotation, but with hammer, stakes are so much easier to drive, vs the manual hammering. We use 1800mm 16mm copper coated steel rods over here in New Zealand, in places the soils is quite stony, trying to bash one of them in with a hammer, is going to take you a long time. The bolts and nuts you had were galvanised, not stainless, stainless is not a blu-ish colour, I insist on using Res-Q-Steel Anti-Sieze paste, (although there are others). In saying that though, if you're that concerned about corrosion, use self-almagamating tape, over the whole junction, to exclude any moisture. Top marks on the checker-plate inside the back of your van, I quite like that look. Maybe I might have missed this, but you haven't introduced your new guy? With respect to the "DJ Cut-off switch' you mentioned, I fail to see how any equipment like this could be damaged by instantaneous loss of power, if this is really a thing at all, require the DJ to provide some sort of a UPS for their gear. Finally, that switchboard that you were showing in the last part of the video, it really pisses me off when you see multiple wires going through a single cable gland. Is it really that hard to get some adapters for the other knock-outs in the bottom of the board to put smaller cable glands in? That whole thing looks like an apprentice wired it.
Tom...why are you using non extendable rods? If your reading is too high what will you do..apart from put another rod in at the set distance.We drive 3/4 of the rod in...carry out a test ..and then we know if we need to extend..just saying :-)
I too, use stainless hardware where mechanical connections are made. Galvanic corrosion is almost a ridiculous argument with an earth rod, considering most are copper clad steel or a copper clad hard brass. It's going to corrode. My preference for earth rod connections, particularly in places where I know frequent inspections won't happen (I commonly do work in multiple countries, with many different rules & laws) is to thermally weld the rod and earth cable together using something like cadweld (other brands are available).
You do not need to drive a ground rod in. In fact if you strike some ground rods with a hammer, you have ruined it. You can make a small depression in the earth, fill it with water, and start jabbing the ground rod up and down. As long as you keep water in the hole, and keep jabbing It up-and-down, It will go in easily. With no damage. Don't let it dry out. Once it dries, the rot is set. It will be difficult to get it out. But as long as it is wet, you can pull it up and down without a problem.
Everyone’s got an opinion. Pretty sure if there was a fire that’s going to do a lot more damage to the DJ’s equipment than suddenly having the power switched off.
Love the channel. Top tip, bin the serrated washers and get Nord-lock, (ok they are much more expensive but), any other washers are shite/garbage. You will spend less time going back to failed fixings. Keep up the great postings. Joe.
Your opening speech....I can relate to that hopefully your prove them negative people wrong by getting your 100k subs videos are great! I can always remember when I was at school and people made me out to be a failure and said I wouldn't get anywhere in life. I started off doing electronics making pcbs in a factory then made it to a engineer doing security install and service and I've proved everyone wrong that called me a failure so they can all eat my farts!!!!
Most audio equipment is fine having the power shut of (mostly how people do it anyway), the only problem would be if the dj is using lights with discharge lamps which need to cool of f being turned off, but then they would probably be the cause of the fire. (If i was the dj i would want more than a double socket)
I worked on a Starbucks refurb at Leeds Bradford airport, and the audio speakers for the shop were wired to an interface for the fire alarm and flight announcement tannoy. Though I'd put it out there for you as a possible alternative to look into. Great work and enjoy your videos 👍
If the contactor goes off and stays off it won't do anything to their equipment unless they're running an external hard drive and writing to it. Of course in my live sound setup I usually if I'm unsure of the situation bring a UPS and I like to run everything so.... everything should be fine going off and staying off as long as it can be brought back up in sequence. the only concern would be non battery-backed data storage, which would only be a concern if they would be recording and if they're recording and they don't have battery or a bus powered Drive attached to a laptop with good battery ... well. I was thinking about the announcements last time but didn't bring it up, you do make a good point it's a small space and most likely the kind of talent they have there won't necessarily get that far?
@thomasnagy If you want locking washers that won't come loose without a wrench, you might have a look a Nord-Lock, my oilfield mechanic friend swears by them since they won't vibrate off. I've even seen him take his brand new grill & bin the factory fasteners so he could swap his own in.
fitted a few of them (Q)cudis boards last year... found them quite nice to fit but i suppose it hasn't got fusebox written on them so they must be shit.
4 ปีที่แล้ว
Earth electrodes... I used to wrap the cable/bolt termination in denso tape, also the checker plate is fucking spot on
Tom great content been watching for ages enjoy seeing someone who takes pride in their work, with regard to the parking tickets did you move the van between getting them? if not shouldn't you only get 1 every 24hrs and I guess you weren't there that long
I hate toggle fixings. If you have to remove the accessory they’re gone. I prefer splaying wall anchors, super strong, available in different sizes and you can take accessories on and off whenever you like.
hang on.... if you get comments about they might need the microphone to alert.... then the fire alarm is not loud enough..... more sounders and VAD required....... cutting the power is exactly how the audio level units work too.
21 years old Taken a year out after my A-levels, planning on going to uni in September to study Business however I am toying around with being a spark. Anyone got any advice for me?
Try do some work with a local sparks assisting them. See if you enjoy it & make a decision from there . You’ll either fall in love with it or think sod this!
I'm sure the company would rather their punters out and safe than worry about their DJ equipment. You can replace that. Great video Tom, that's a nice job you got there. Make sure to show us when it is finished, maybe when trying the place out slumped over the bar ! 😂
I am working on an old factory in Wolverhampton. Refurbishment and bringing it out of the dark ages without a million pound complete rewire. Old style circuit breakers that can't be locked in the off position. Does anyone know of replacements or would simply having tags or notices available bring it up to spec. I don't think it's every had an EICR.

I got a parking ticket once and I still think about burning their offices down today.
best to do it now whilst it is empty to avoid the murder charge
I agree, we are in the middle of pandemic and they still want to slap tickets, they need to show some respect! 🤦♂️🤦♂️🤷♂️🤷♂️
Here in Brighton and Hove Parking Officers are not giving tickets unless you vehicle is parked dangerously, causing an obstruction or parked on Zig Zags. This will change when the lock down comes to an end.
Probably safer to push used tissues through their letterbox

Traffic wardens are clearly 'essential workers'
Neal F can you imagine the state of London if people were let park anywhere they want with no come back? Its bad enough with enforcement in place lol
My fuse board is in a dark cupboard under the sink, they fitted this board and it works really well. A bit of light in a dark cupboard so you can see makes the hell of difference.
You should get the SBS bit for earth rods to put on your impact drill, you can use it for expansion bolts as well
Very true mate
We have an SDS bit for earth rods in my country, you can try looking for something like it. Hammering by hand is a pain in the ass
just make one out of a worn down sds chisel and put some ø16mm pipe around it,it doesnt hit with the pipe anyways its only there to keep it in place so its plenty strong.
Sent over by Big Clive. I'm an electrician in the States; it's interesting to see the differences across the pond. Liked and sub'd...
Got to love Big Clive. What will let out the magic smoke or angry pixies next.
We use Denzo tape around the earth clamps in Ireland...thick extremely sticky tape the protect the clamp from water ingress and corrosion
Just on the DJ cut off switch, I would make the contactor normally open and energised in normal operation. Just to make it fail safe.
Mc Carly I’ll second this, the last one I fitted was wired like a DOL starter where there are on/off pushbuttons and a 24v interposing relay powered from the fire alarm panel via the aux contact, so when the alarm sounds the relay drops out and so does the contactor. This way a loose connection, damage to a cable or failure of a device is more apparent
I agree with you about the corrosion on the earth rod clamp but isnt that why we do continuous inspections of properties ?
If you're worried about corrosion between the stainless and brass stick some tefgel (or similar) on it, it's what we use on boats and does an amazing job of stopping bolts from seizing.

DJ cut off switch is the worst dj name ever!
But the easiest job ever. They book you for an hour slot between 1 and 2am and you just walk in, turn it off and fuck off \(^_^)/
I had the misfortune to do gigs at a venue with a stage power cutoff driven by a decibel meter, which was a stipulation by the council. If the audience started to sing along it would trip the power :( Just had to refuse to work the venue , and get clients to use different venues.
I always use the larger earth rods that you can join just in case the meter reading is crap. The earth connection is a clamp rather than a bolt.
Thinking about earth rods I have been out to a few domestic properties in rural areas where the tenants have brought a say a new cooker delivered from a store and the engineer won't connect it as the Zs readings on there are higher than they are used to on their multi meter or whatever they are using( doubt it's a multifunction tester) I go out do a zs test and it's perfectly fine well within tolerance.

Fire alarm should have a contact that is energised when the alarm isn't active. Use that to feed the contractor and feed the supply to the sockets through normally open contacts. Sockets will then cut off when the alarm sounds or if the cable gets damaged.
I was going to say that. Thank you. Safety contactors must be energized when operation is safe and do the safety thing when the current is cut off
Wesley Potter 👍 100%

Yep had those brass bolts shear

The other way is to water drill with a hose on a length of 15mm copper.
Thomas, re those LED lights, on your UK OFCOM site, there is a story about an airport, I think in Scotland, where the pilots were complaining that at a certain location near the airport they would loose all radio communications with the tower and air traffic control (not a good thing). After investigation, it was found that the source of the radio blackout was caused by an LED lamp, the type you get from the Asian mail order vendors, the lamp did not conform to ANY type approvals, the lamp was binned, radio service returned to normal.
John Hill theres no way an LED lamp is drawing enough power to disrupt all radio comms on modern aircraft
Hey Thomas I didn’t know if you new they make a ground rod driver that fits in a standard rotor hammer
Have you considered using a post driver for the first several feet of sinking an earth rod? They are not expensive but will take up a bit of room in the van and you will still have to drive that last 2 feet with the hammer. But, you will reduce the risk of finger bashing by 2/3rds... love your stuff. Wish we had ring systems here in the states.
English soil is soft, he have to use hammer drills down here in New Zealand to drive our Earth Electrodes.
I do like a bit of cable husbandry on my boards that I've fitted, used to take so much pride in the flow of the terminated cables, hope to get my flow back after this lockdown is ended, just emergency calls right now for a third party. be nice to go back to a few and make them pretty for future works.
I would for sure use a normally open contractor for this purpose so that you aren’t dependant on having power to the control ctt to control the output
But if you loose power the DJ equipment will surely stop working anyway 😕
For safety it quite normal to require the power to hold the switch on, so if the cable gets damaged at any time it will stop the DJ working so will get fixed asap.
kw1984 it’s more about relying on the presence of power that has no back up psi to activate a safety device. Fire alarm out puts almost always work on a energised relay in normal state/ de energise in fire conditions.
Many DJ mixers have inputs for fire alarm systems that mutes the audio rather than cutting the power.
Tom use denzo tape on top of earth rod clamp, that's what we do on the motorway feeder pillars , then no corrosion
In Ireland Denso tape is a requirement. (And rightly so.)
could you do a van and power tool tour
Yes, the back of your van is "smart". Love that checker plate install. Probably easy to clean also.
Have you got Chapter 8 Chevron markings on the back doors of your van to help with the Parking Ticket situation (think you already have amber LED beacons already)?
Those toggle fittings are the mutts nuts!! In ireland our earth rods and clamps are galvanised steel. Ive never seen one snap here like the ones you showed here.
Someone years ago taught me how to drive a 8ft/2.4m ground rods without a hammer. In my area the ground rod has to be buried. When you dig the hole you fill the it with water and just stab the rod in the ground. You move the rod up and down and the water makes it so the rod almost falls into the ground. You just have to make sure you have water in the hole when you are doing it.
Brass and Stainless Steel together; Galvanic corrosion risk is minimal as they both have similar "Noble Potentials". In my marine experience you would also not directly seal stainless connections as these accelerates corrosion, so boxing it as you do is good. You could also save a lot of washers by using nyloc nuts, I by these along with the nuts and washers from Screwfix in bags.
Did I miss a video or something or is that a new worker?😅
He's a hologram of Dave.
Feel like on original , ore one of the originals , been highs and lows , Dave's come , gone , come back and gone again ! But through it all you've kept your head high and the videos rolling
Have you tried a sds drill on hammer only for putting earth rod in ?
I recently moved to London and was shocked at how messy and unmarked DBs were over here, not all but quite a lot of them.
Let me guess you’re Australian?
Kum Hydrant haha no British isles
Can’t you use stabilising gel to combine 2 metals. And stop the dissiminstion. As 2 metals in contact will cause corrosion. But there has to be a lubrication type gel for combiining metals. 😇. Harry.
A few years ago, my parents moved house. It made economic sense to rewire it (in so far as it wasn't life expired but by the time I'd made the changes that they'd wanted it was quicker and easier to just rewire). I always try to make my panels neat, and this was no exception. Anyway, I did the main part of the house and they had some building work done - the builder insisted on providing their own trades. Once their spark had been at the board, I opened it up and they'd just lashed in the cables. My stuff was neatly dressed, theirs was just run in anywhere - I dread to think what their boards look like.
I’d always have life critical controls or associated controls as normally open so they’ll always fail open rather than stay closed if for whatever reason the controls supply fails 👍 this is obviously dependant on what you want to control and whether it’s better that the thing being controlled needs to carry on functioning during an emergency but a sound system I’d be putting in normally open contactors.
Love the pedant-teasing 'bulbs - sorry, lamps' bit! I believe Mr Savery feels much the same, though he'd be a bit more 'flowery' in his language. I imagine him saying 'every c*** knows what a f***ing bulb is for boll***'s sake' kind of thing.
If the DJ's equipment could be damaged by unexpected loss of power then the DJ hasn't built his equipment stack correctly. Clean power in from the supply company is never guaranteed, so they should have no expectation of it unless it has been previously agreed that the landlord will provide it (eg in a data centre). DJs should have their own power conditioner, and/or UPS (imo).
I'm a DJ - Sudden power loss doesn't cause damage to your equipment at all, it's just people trying to have an opinion on something they don't fully understand.
If in the rare case it somehow did, likely the equipment was already faulty and probably shouldn't be in use anyway!
Use a earth rod driver,got a few for my sds drills, one is a (Bosch 2608690010 Rod Driver) , cost about £11,prevents the mushroom on the earth rod.
You want to get the earth rods that allow a screw on cap, i thjink they're 1/2 inch ( i dont know the exact name but they screw on and look like a bolt on the top) It allows you to hammer the rod in and if you don't get a good reading you can attach another rod and continue hammering to get deeper as it doesn't ruin the thread and it saves you having to use a hack saw.
They're 5/8" - not 1/2".
Tom you are the godfather of electricians on TH-cam
Must be some soft ground we generally use a big hammer drill to drive the ground rod here in Texas .toggle bolts been using them 40 yrs
TEX wet clay and mud is all we have in the UK
In fairness, they have been in the UK since 1934, invented by Rawlplug.
I've been with safe contractor for a while. It's an utter nightmare. Especially when I have to prove ongoing health and safety training to my staff... And it's just me 🙄
And if there is no "liquid" involved bimetalic corrosion cannot occur.. for example in the chambers you can buy and cement into the floor ???
Dissimilar metals will for certain react with each other especially with a small current passed
tomorichard Thompson Need some of that bi-metallic paste/grease
Pro Audio equipment is designed to have power-loss. There is no active sensitive components (like hard drives)
Best bit about the channel is the no bullshit honest bits
@ Thomas Nagy,
A few points:
With respect to driving Earth Stakes, if you have a Hilti hammer drill, get a deep socket that fits on the end of the drill chuck, put it on non-rotation, but with hammer, stakes are so much easier to drive, vs the manual hammering.
We use 1800mm 16mm copper coated steel rods over here in New Zealand, in places the soils is quite stony, trying to bash one of them in with a hammer, is going to take you a long time.
The bolts and nuts you had were galvanised, not stainless, stainless is not a blu-ish colour,
I insist on using Res-Q-Steel Anti-Sieze paste, (although there are others).
In saying that though, if you're that concerned about corrosion, use self-almagamating tape, over the whole junction, to exclude any moisture.
Top marks on the checker-plate inside the back of your van, I quite like that look.
Maybe I might have missed this, but you haven't introduced your new guy?
With respect to the "DJ Cut-off switch' you mentioned, I fail to see how any equipment like this could be damaged by instantaneous loss of power, if this is really a thing at all, require the DJ to provide some sort of a UPS for their gear.
Finally, that switchboard that you were showing in the last part of the video,
it really pisses me off when you see multiple wires going through a single cable gland.
Is it really that hard to get some adapters for the other knock-outs in the bottom of the board to put smaller cable glands in?
That whole thing looks like an apprentice wired it.
Tom...why are you using non extendable rods? If your reading is too high what will you do..apart from put another rod in at the set distance.We drive 3/4 of the rod in...carry out a test ..and then we know if we need to extend..just saying :-)
Can you do a van tour and power tool tour
I too, use stainless hardware where mechanical connections are made. Galvanic corrosion is almost a ridiculous argument with an earth rod, considering most are copper clad steel or a copper clad hard brass. It's going to corrode. My preference for earth rod connections, particularly in places where I know frequent inspections won't happen (I commonly do work in multiple countries, with many different rules & laws) is to thermally weld the rod and earth cable together using something like cadweld (other brands are available).
Maybe it's just me but I felt like you had a lot more fervour in your words/actions in this upload. Love it as always, keep it coming!
You do not need to drive a ground rod in. In fact if you strike some ground rods with a hammer, you have ruined it. You can make a small depression in the earth, fill it with water, and start jabbing the ground rod up and down. As long as you keep water in the hole, and keep jabbing It up-and-down, It will go in easily. With no damage.
Don't let it dry out. Once it dries, the rot is set. It will be difficult to get it out.
But as long as it is wet, you can pull it up and down without a problem.
Everyone’s got an opinion. Pretty sure if there was a fire that’s going to do a lot more damage to the DJ’s equipment than suddenly having the power switched off.
It does - lost a amp to it
False alarms - the sudden thump of a mixer or amp being turned off has been known to kill speakers.
no one likes audio wankers
Exactly, these knobs need to buy a UPS.
@@MrLimeGrass How exactly?
Love the channel. Top tip, bin the serrated washers and get Nord-lock, (ok they are much more expensive but), any other washers are shite/garbage. You will spend less time going back to failed fixings. Keep up the great postings. Joe.
Your opening speech....I can relate to that hopefully your prove them negative people wrong by getting your 100k subs videos are great! I can always remember when I was at school and people made me out to be a failure and said I wouldn't get anywhere in life. I started off doing electronics making pcbs in a factory then made it to a engineer doing security install and service and I've proved everyone wrong that called me a failure so they can all eat my farts!!!!
nice info about the Rod bolts 👌🏼 I’ll keep that in mind
Most audio equipment is fine having the power shut of (mostly how people do it anyway), the only problem would be if the dj is using lights with discharge lamps which need to cool of f being turned off, but then they would probably be the cause of the fire. (If i was the dj i would want more than a double socket)
I worked on a Starbucks refurb at Leeds Bradford airport, and the audio speakers for the shop were wired to an interface for the fire alarm and flight announcement tannoy. Though I'd put it out there for you as a possible alternative to look into. Great work and enjoy your videos 👍
Is it ok to leave the large hole in the ceiling behind the pendant? i.e.does the metal fixture provide a sufficient fire barrier?
If the contactor goes off and stays off it won't do anything to their equipment unless they're running an external hard drive and writing to it. Of course in my live sound setup I usually if I'm unsure of the situation bring a UPS and I like to run everything so....
everything should be fine going off and staying off as long as it can be brought back up in sequence. the only concern would be non battery-backed data storage, which would only be a concern if they would be recording and if they're recording and they don't have battery or a bus powered Drive attached to a laptop with good battery ... well.
I was thinking about the announcements last time but didn't bring it up, you do make a good point it's a small space and most likely the kind of talent they have there won't necessarily get that far?
You are the king of the candid video starts
Can i just say tom im glad you stuck with you tube.. you give me something to watch while te wife watches soaps😁 keep up the good work and stay safe
Did you ever fix your ladder rack ?
@thomasnagy If you want locking washers that won't come loose without a wrench, you might have a look a Nord-Lock, my oilfield mechanic friend swears by them since they won't vibrate off. I've even seen him take his brand new grill & bin the factory fasteners so he could swap his own in.
Could you you fashion something to fit into your hammer drill to drive them in?
Thomas, have you thought about using systainer boxes and trolleys for your tools. I have been using them for a few years and could never go back.
Harvey Smith he clearly uses L-Boxxes for his Bosch tools. Made by Sortimo, which coincidentally kitted out said van...
I love how your hairstyle changed 2 thirds of the way in 😂
fitted a few of them (Q)cudis boards last year... found them quite nice to fit but i suppose it hasn't got fusebox written on them so they must be shit.
Earth electrodes... I used to wrap the cable/bolt termination in denso tape, also the checker plate is fucking spot on
Did you sort that van out for tour Father? You did say,watch this space months ago!
Tom great content been watching for ages enjoy seeing someone who takes pride in their work, with regard to the parking tickets did you move the van between getting them? if not shouldn't you only get 1 every 24hrs and I guess you weren't there that long
Is that a just over 2hr stay parking ticket for an hours work and an hours work of recording then bill it to the customer?
Thumbs up on the checker plating Tom.
With London being so quiet, are there still packs of traffic wardens prowling the streets?
An, fair enough. Hadn't watched all the way to the end 😆
I hate toggle fixings. If you have to remove the accessory they’re gone. I prefer splaying wall anchors, super strong, available in different sizes and you can take accessories on and off whenever you like.
that is a major downside to them. once you take the screw out, its pops off in the ceiling. its a one time only fixing
Try a Rawl gun for your cavity fixings. Available from Screwfix
You can drive earth rods using an SDS on hammer only
hang on.... if you get comments about they might need the microphone to alert.... then the fire alarm is not loud enough..... more sounders and VAD required....... cutting the power is exactly how the audio level units work too.
21 years old Taken a year out after my A-levels, planning on going to uni in September to study Business however I am toying around with being a spark. Anyone got any advice for me?
Jacob Roberts
YEA...GO TO UNI
Dont fucking do it
Try do some work with a local sparks assisting them. See if you enjoy it & make a decision from there . You’ll either fall in love with it or think sod this!
Mahony_johno haha, you really think so? Always nice to hear from other peoples opinions with plenty more experience than myself
Pingu 86 cheers, any reasoning behind not wanting to go down the electrician route?
I'm sure the company would rather their punters out and safe than worry about their DJ equipment. You can replace that.
Great video Tom, that's a nice job you got there. Make sure to show us when it is finished, maybe when trying the place out slumped over the bar !
😂
Agreed! Safety is the main priority 👍🙂
Bob's your uncle, yes I've got one of them , but not an aunt Fanny , she definitely had one !!😁😁🇬🇧🇬🇧
Facepalm!! ... Get the fek outa here! ... LMAO!
_Americans may not get the proper joke!_
I am working on an old factory in Wolverhampton. Refurbishment and bringing it out of the dark ages without a million pound complete rewire. Old style circuit breakers that can't be locked in the off position. Does anyone know of replacements or would simply having tags or notices available bring it up to spec. I don't think it's every had an EICR.
Surprised no one has made a fit over anvil to the earth rod
There's and adapter you can but that fits onto an sds, pretty good.
