Jordan, seriously fair play to you mate. I’m a sparks and also have my own business. To be very honest, I’m extremely fed up of the trade and day by day this feeling is getting worse. For you to not only be doing the work and enjoying it, your also spending even more time filming and editing it. Wish you all the best with your business and TH-cam career.
76 year old electrician, part time these days but still love working on the tools and the satisfaction I get from doing a good job, love your videos and the quality of work you guys do.👏👏👏.
Is nice to see you on the tools Jordan. I worked at an Australian Govt building construction fire research lab. The fire separation integrity is something that so many trades don't give a toss about, from domestic to commercial. That cutting of the ceiling is shocking. I also question the polystyrene beads. If fire got into the cavity they'd probably go wooshka.
In WA the fire integrity of the domestic switchboard was the main item picked up by the Western Power inspectorate. They're recently relented as there has never been a domestic switchboard fire that has spread into the property!
in most of Europe it became illegal to use PS as insulation in the late 1980s or early 90s (depends on country), because of the fire hazard. And while it's been replaced by proper insulation in most places, since the PS foam is terrible insulation as well, in the UK old installations will remain until it becomes necessary to pull it out. Many houses built before between WW2 and the 1973 oil crisis merely had a cavity between the inner and outer walls, to act as the only form of insulation - and this goes for all of Europe - so some chose to blow the cavities full of PS beads to provide some kind of insulation. In Denmark they instead used proper insulation mats chopped up into tiny pieces, which is a lot safer and more efficient, but don't know if it was done in any other places.
Hi Jordan, although not an electrician by trade, I do watch and enjoy every video. Great team of installers, keep us all smiling, witty, cheeky but turning out consistent quality work..perfect.! Cheers, Alex.
23:29 Funny to hear that! Sjongejongejonge is a Dutch expression when you're very amazed/frustrated by something or struggling with something. Your impression was quite good :-). I hope you understand! Cheers from the Netherlands
The cavity is full of insulation good luck not getting any touching cables. If that concerned why not drill larger hole and put some copex, trunken, conduit or whatever in to prevent any issues .. you made issue about it then don’t negate it .
I love watching your channel Jordan!, I am a QS but have been an Electrician for over 30 years, mostly on commercial. I love when you find "shocking" or "mad" wiring, as I mainly think that you have seen nothing (not a criticism, you have probably just been lucky) compared to some of the commercial or industrial installations I have come across over the years, its difficult not to become desensitised to some of it. Keep up the 5 star life!!
I once came across twin and earth deterioration when installing a new bathroom. Behind the walls were sheets of polystyrene insulation and the old cables had been sitting against it for years. It wasn’t all the way through to the conductors but the outer sheath looked like it had melted at parts
I had a Thai worker cut a hole in cement board to fit a outside socket for a friend on a outside wall it was a cement board and the internal wall plaster board filled with polystyrene beads for insulation . When I arrived at the job all the beeds were out of the wall in that location. I bagged as many as we could recover. He did not attempt to stop the flow. The Thai worker got the job to fill the cavity from the roof space very hot and sweaty. The joys of Electrical work in Thailand. Love the vids. A fountain of Knowledge.
Dave Bruce , hi, when going through the cavity, can you drill slightly larger so you can put a length of plastic conduit all the way through to protect cables from insulation pellets?
Tsjonge jonge indeed. Always surprised to see where you find the consumer unit. Being Dutch, we always find it in the same place, right above the meter, within 3 meters from the front door.
The expression "Tjonge jonge jonge....." is an understatement for the loose connection block. Inside the board is a "tjonge jonge jonge" situation, it's more used if you wonder why some did something in a certain way. Greetings from the Netherlands.

Hey I'm a learning electrician who's finished studying. I'm now working on site with a qualified electrician doing my NVQ. I'm looking in to buying an electrical MFT. I seen a video of you unpacking the Fluke 1664 FC is that a good Tester to buy?
Whilst I never saw any plastersizer issues I did see issues with washing up liquid! In the 80s I was looking after multiple estates in south east London constructed from preformed concrete. In one particular estate we started to see ring mains going down regularly. We found when pulling the cables out the insulation on the single core was completely liquified. it was found that when the cables were installed they did not put conduit in the walls. They simply hale preformed "conduits" in the concrete. to get the cables pulled through they used to use washing up liquid! 20 or so years later this broke the cables down causing issues. Residents used to complain of goo oozing out of sockets or in some cases "fizzing" in the walls. The resolution was to rewire using preformed skirting trunking.
The dutch expression "sjongejonge" means pretty much "boy o boy". You said it exactly right, making it clear to anybody that's an expression of being surprised in a bad way by some dodgy stuff you just found. :)
Me coming from a 35 amp main fuse in the Netherlands. Funny to see the difference between countries. My greatest culture shock is the placing of the meter outside and the main fuse box just placed wherever there's space. How different with the "metercloset" in the Netherlands
It depends on the age of the property. Many new builds have a meter cupboard outside to house the meter and incoming fuse... older properties have it inside the house, usually in a cupboard under the stairs or the likes :)
3 ปีที่แล้ว
Our meters in the US have always been on the outside. Since we have changed over to smart meters all reading is done remotely from the main offices. Also, most homes have a 200 amp main breaker.
@ At least your panels are built to a conservative industrial standard and will probably be good for 50 years. Here it is a race to the bottom. Before the recent requirement for metal enclosures, some consumer units were little better than tupperware sandwich boxes. And equally flammable. And you can get MCBs for the budget ranges for around £2
Well, "sjonge jonge jonge" (translates to something like "oh dear oh dear") is surely appropriate here! Good thing for the customer Artisan is there now to do their trademark quality job!
the insulating beads jam a long nozzle with expanding foam in there early into the job quick squirt then wait a bit, once it dries drill through that should stop the beads coming down.
Polystyrene beads:- What about drilling a much larger diameter hole and feeding a large diameter insulated fibrous shroud and feed that through, then inside that, insert and feed through the power cables you wish to use?
I'm not an electrician but it happened few times to find some old device still in the box with the original polystyrene packaging and the cable was "melted" into the polystyrene. This is why is best to bag the item before putting it in contact with the packaging and coincidentally this is actually how you find most new devices
Ah polystyrene cavity insulation joy o joy. Normally sleeve it through the wall, beads have a habit of eventually coming back out if you don't sleeve and seal. Don't tend to like using tape as depending on the tape it can also cause issues over time with insulation. That said worst one I came across was 16mm tails on an 80 Amp incomer with bead insulation in the wall un-sleeved - after 5 years the DNO fuse had popped due to the installation being at almost constant maximum demand the heat combined with the polystyrene had caused the insulation on the tails to for want of a better word melt and then directly short out. Only seen it that bad once, never since but this is going back 15 years now see the odd one but no where near as bad, just dimpled and the balls stuck to it.
love your enthusiasm for your trade. I'm a 63yr old Plasterer that gets very disappointed with the standard and lack of pride in the youngsters in the trade now. Really enjoy your vids . thanks. ps watched your Electric van vid and would definitely NOT be getting an Electric powered van. lol
Fascinating. I served my time in the 60s 14th edition. It was during the changeover from the likes of 7029 to 2.5mm squared and ft lbs became Newtons per metre squared etc. While the craft side of the job is still broadly the same, the inspection and testing has moved on considerably, as have the regs. I left the trade in 1971, eventually becoming a rocking horse maker for 30 years.
15:23 That's funny, here in the USA we typically use 6AWG (16mm2) or 4AWG (25mm2) for the Tesla chargers depending on the distance. As small at the Tesla base is to work in is fun with rear entry and even 6AWG wire it become almost impossible with 4AWG and while being stranded, its very stiff still. I would love to be able to use 12AWG (4mm2) or 10AWG (6mm2) cable. However with 11.5KW (48A) we have to use much larger wire. Keep up the good work sir.
I’m never convinced that allowing a person outside your house to isolate your electrical supply is a good thing? I think I’d like a steel door and padlock on mine… but I’m from Manchester!
Go over to some parts of Australia - the whole consumer unit is often outside in an open porch secured by - nothing! Water valves similarly often in the open. Guess they are more honest over there - despite the convict past!
@@barrieshepherd7694 When there well located, sometimes it's around the far corner of the house accessible via a narrow garden between the house and a fence. And yet the reg's only require the meter and the main service fuse to be outside!
I retired 3 years ago and all my old boards were pretty smart, i fitted a flue for a hob exracter at 4 " and those bloody beads filled the garden, no hole saws in those days so hammer and chisel.
It looks like you have the live and the neutral both going through the red CT on the charging station at time 30:49. Shouldn't you have just one wire going through the CT ?
I can’t agree with you more Jordan. There is something really satisfying about working on the tools and seeing what you’ve actually done at the end of the day. Fault finding and fixing issues is without doubt the most satisfying, and you always have a happy customer as they can now use there upstairs lights, or take a hot shower etc. It’s instant feedback.
I was working in a loft once that had polystyrene ball insulation. The cable insulation had become sticking to touch. I told the homeowner and got the usual reply when I give bad news 'no one else has said that'.
Great job tidying that dogs dinner up in the cabinet Jordan! It's always difficult when you have to tidy things up temporary when you know you'll be back later to rip it all out again. But, regs are regs.
Excellent work Artisan team. I’m from the U.S. and I find it so bizarre that you don’t use conduit for exterior ran wires. I know the cables rated for outdoor but why isn’t conduit used? IMO it would look waaaay nicer especially when painted as opposed to a wire with clips.
The way you handled that drill bit I see the rumour is true, that your starting your own Fracking Company. 😀😁😂 Regarding the leaching, definitely sleeve across cavities. What to do with the beads afterwards. Collect them all up go into the loft and drop them into the cavity or drill another hole and put the Hoover on blow 😁 The effect looks a bit like black spot on a sycamore leaf. I wonder if JW has looked into it. 🤔
STOP cavity wall insulation falling out - You might like to try drilling 4 holes at 90 degrees to each other around the area where you likely to be working, say 100mm apart in a north/east/south/west configuration then inject Expanding Foam (Fire Rated) if you think it is beneficial to add a fire break then once it has had time to dry, that will keep the polystyrene beads in place. Unfortunately, losing the beads around the area where you’re working not only makes a mess, but you could end up creating a cold spot/possible cause a condensation problem in the future as well degrading the heat retention properties of the house.
Believe the plasticiser migrates from the polystyrene to the pvc, the polystyrene breaks down and leaves a sticky residue on the outside of the pvc insulation but it doesn’t degrade it.
In Germany we avoid the plasticizer migration by using a piece of this white rigid conduit so the cable is not in direct contact with the polysterene. They are also made of PVC, but since they're rigid, they contain no plasticizer and so cause no trouble. About that dutch expression, I would say roughly something like "oh Boy!"
Does this actually affect the PVC? I've seen it happen a few times and as far as I could tell it was only melting the polystyrene, the PVC was fine. Plasticiser leeching out of PVC is a normal process but usually doesn't hurt cables much, they just become a bit harder to strip if you're doing any alterations later on. I've worked with PVC cables as old as the late 1950s and they were all perfectly fine, unlike the older VIR.
never seen plastersizer used as wall insulation before as it is very flammable. in old houses here we can find sawdust used as insulation, usually there is glasfiber wool and rockwool in later installations.
As a matter of interest, when you do an EV charger install, what paper work, test results etc, do you leave with the customer. I have just had a Wallbox installed by Octopus Energy via a their contractor and a sub contractor and got nothing which surprised me. Went for 10mm SWA as it was 30m of cable across a lawn. Probably overkill but future proofing. It is a pity that I am to far from Cambridge to have asked you about doing it.
Re problem of wall cavities. I like to slide some 20mm PVC conduit through to guide stubborn cables through the cavity as well as protecting them from polystyrene and rodents (maybe). Only problem is a 20mm drill only seems to make a 19mm hole. So I take off-cuts and pass them over my table saw at home, just to put a single 3mm slot in the pipe. This closes up and reduces diam.of pipe when you push it through the wall. Will take 6mm SWA.
I now understand why some people give J it tight . There is something annoying about his voice and way he interacts.. but hey everyone different and the guys done well so well done 👏
Drill an oversized hole and run rigid PVC conduit through polystyrene-insulated walls. It's just cleaner, easier to work with, and any future spark will thank you. Horrible stuff.
I have had problems with the insulation beads coming out of drilled holes. If I find the cavity is filled with these I inject foam just above the hole to hold the beads in place drill another hole inject there drill though this foam no problems.
That corrugated plastic pipe from the fan unit to the outside is going to be half full of condensed water soon. The fan and pipe should have been elevated to cause condensed water to drain towards the outside and the pipe up from the bathroom (and preferably to the outside) should have been double walled / insulated.
no problem in the Netherlands with the insulation. we do not use this type of insulation material for cavity walls. sjongejongejonge, I am always amazed at how much difference there is in electrical installations in different countries. in the netherlands it is out of the woods that individual conductors are installed without protection. keep up the good work guys.
Meggar leads are meant to be plugged the other way on the tester, so the right angle connection is pointing towards the front not the back. Something to do when they are pointing backwards you can put pressure on the bends forcing the internal connections apart causing false readings.# Or so I have been lead to believe
I’ve only fitted two EV Chargepoint’s. One was a Hypervolt, and I was assessed on it as part of my yearly NICEIC domestic installer assessment. My assessor said I should have attached a document from Hypervolt to the EIC for 722.411.4.1 compliance. As I didn’t do this, he recorded it as a non-conformance. I have asked Hypervolt for guidance but they haven’t come back to me on this as of yet. Just wondering if you guys know much about this? Thanks, Jim
Why not install the new board with 3 circuits initially, the ev charger and two feeders to the old panels, then take out those feeder circuits when you move everything out of the old panels.
My distribution board connecting over 50 years as an Industrial electrician was quality,if you want a sample of my work go to Norfolk and Norwich Hospital where I connected a few
There’s is such a massive problem in the trade at the moment. I’m charging clients £550 +VAT to replace there consumer units. Lately clients have been responding with I’ve been quoted £150.. it’s impossible. How an earth does that even add up. It’s getting worse and worse. I have had to lower my prices massively and even with the reduction people are still saying they are getting quoted half the price. I don’t know what is going on but what I do know is that it’s messing everything up. Have you been affected in this way at all?
He's an accredited domestic installer; many DNOs will officially allow such people to pull the main fuse. Even if you aren't, at the end of the day, safe isolation trumps all, and if the only way you can safely isolate the installation is to pull the main fuse, and you need to isolate the installation to do the job (e.g. board change), no DNO is going to ding you for that in practice, as long as you inform them so that they can come and inspect it after (to verify you haven't bypassed the meter) and seal it up again.
@@aaronmdjones well if that's the case why don't they just say that, but is it the case the dno don't like it being done and that's why they never tell you how they safely isolated the circuit
Henley blocks with exposed copper seems like a bit of an issue more than the usual run of exposed copper - that’s a cat IV, 60-100A fused electrocution hazard, not “just” a cat II or III one with RCD protection. Yikes.
Ahem .... sorry if it appears I am being a pedant BUT the 0.18ohm you said was the Ze wasn't. The green croc was attached on the earth bar which had circuit CPCs on it and the earth tail in the board went to the MET which had the main bondings and other board earths in place, which would have brought down the resistivity due due parallel paths. It is more sort of a Zdb wouldn't you say Jordan? Other than that I enjoyed your vid as usual. I love my 1741+ and glad to see you like yours. Will they let you keep it?
I will never understand why the UK allows those horrid board placements. There is no other country in Europe where it's legal to supply power to an installation like that. It's "either get a proper mainboard or live in the dark". And yes, doing it the mainland way starts around £600 for the mainboard installation, but then it gets done right, it's properly accessible and safe, and you don't have to chase all over the place looking for different boxes because everything is (and has to be) contained in one place.
Why not have the charger for the car nearer the car, to the left of the company fuse, else too close to crosswise wall? Fire-resisting foam will sort out the insulation problem. You are so right I hate lounge-lizard tasks, doing it is better. However you cannot get the staff and to train them slows work. Those you can get want mpre than poorer folk can afford.
All on a 60 amp fuse... wow what a mess. I do like how metal CU, metal boxes, all metal but then install these in particle board / wooden cabinets that are plastic coated! So if there is some sort of event you wouldn't know right away because its enclosed. 💥🤦♂🤷♂ I assume they put a bunch of flammable stuff in the cabinet as well.
@@tobysherring1369 I completely agree with you. Its just funny that they were steel, wood, plastic and then back to steel. Here in the US, a good percentage are located in the wall cavities and are flush mount. That is the norm, unless mounted in a basement and then put surface mount on concrete basement wall for example. There are a few cities like Chicago that require all residential wiring be located in steel conduit throughout the entire house. Luckily here in Texas its just in the walls with NM-B (twin and earth basically).
I am wondering why you never use plastic pipes??Its better outside because off the straigtnes off the pipe.Those plastic bals cant get into contact with the cables etc.etc..Look at that white cable outside!Thats not right!Better with a pipe!Everything is better with a pipe!
This is known from old computers that were stored in polystyrene with cables. The enclosed cable often reacts with the polystyrene. As an non native English I am getting confused about stuff and staff. English is crazy.

You might want to sleeve the cable through the wall if you are having a chemical reaction with the insulation.

I would love to be able to use 12AWG (4mm2) or 10AWG (6mm2) cable. However with 11.5KW (48A) we have to use much larger wire. Keep up the good work sir.
I’m never convinced that allowing a person outside your house to isolate your electrical supply is a good thing? I think I’d like a steel door and padlock on mine… but I’m from Manchester!
Go over to some parts of Australia - the whole consumer unit is often outside in an open porch secured by - nothing! Water valves similarly often in the open. Guess they are more honest over there - despite the convict past!
@@barrieshepherd7694 When there well located, sometimes it's around the far corner of the house accessible via a narrow garden between the house and a fence. And yet the reg's only require the meter and the main service fuse to be outside!
I retired 3 years ago and all my old boards were pretty smart, i fitted a flue for a hob exracter at 4 " and those bloody beads filled the garden, no hole saws in those days so hammer and chisel.
It looks like you have the live and the neutral both going through the red CT on the charging station at time 30:49. Shouldn't you have just one wire going through the CT ?
I can’t agree with you more Jordan. There is something really satisfying about working on the tools and seeing what you’ve actually done at the end of the day. Fault finding and fixing issues is without doubt the most satisfying, and you always have a happy customer as they can now use there upstairs lights, or take a hot shower etc. It’s instant feedback.
I like fault finding but polishing turds gets boring fast.
Sjonge jonge jonge. Wat een zootje. Lekkere video Jordan!
I was working in a loft once that had polystyrene ball insulation. The cable insulation had become sticking to touch. I told the homeowner and got the usual reply when I give bad news 'no one else has said that'.
Great job tidying that dogs dinner up in the cabinet Jordan! It's always difficult when you have to tidy things up temporary when you know you'll be back later to rip it all out again. But, regs are regs.
I guess 4 mill. cable will be too thin for 32 amps when placed inside the polystyrene. This could cause overheating issues.
Excellent work Artisan team. I’m from the U.S. and I find it so bizarre that you don’t use conduit for exterior ran wires. I know the cables rated for outdoor but why isn’t conduit used? IMO it would look waaaay nicer especially when painted as opposed to a wire with clips.
Great to see your attention to the details, not only looks good it give the customer confidence. 🤓👍
The way you handled that drill bit I see the rumour is true, that your starting your own Fracking Company. 😀😁😂 Regarding the leaching, definitely sleeve across cavities. What to do with the beads afterwards. Collect them all up go into the loft and drop them into the cavity or drill another hole and put the Hoover on blow 😁 The effect looks a bit like black spot on a sycamore leaf. I wonder if JW has looked into it. 🤔
STOP cavity wall insulation falling out - You might like to try drilling 4 holes at 90 degrees to each other around the area where you likely to be working, say 100mm apart in a north/east/south/west configuration then inject Expanding Foam (Fire Rated) if you think it is beneficial to add a fire break then once it has had time to dry, that will keep the polystyrene beads in place. Unfortunately, losing the beads around the area where you’re working not only makes a mess, but you could end up creating a cold spot/possible cause a condensation problem in the future as well degrading the heat retention properties of the house.
13:26 What a heart warming moment.
Cant beat getting out on the tools. Nice to see you and Lee working hard at the coal face. Powerful
Believe the plasticiser migrates from the polystyrene to the pvc, the polystyrene breaks down and leaves a sticky residue on the outside of the pvc insulation but it doesn’t degrade it.
In Germany we avoid the plasticizer migration by using a piece of this white rigid conduit so the cable is not in direct contact with the polysterene. They are also made of PVC, but since they're rigid, they contain no plasticizer and so cause no trouble.
About that dutch expression, I would say roughly something like "oh Boy!"
Does this actually affect the PVC? I've seen it happen a few times and as far as I could tell it was only melting the polystyrene, the PVC was fine. Plasticiser leeching out of PVC is a normal process but usually doesn't hurt cables much, they just become a bit harder to strip if you're doing any alterations later on. I've worked with PVC cables as old as the late 1950s and they were all perfectly fine, unlike the older VIR.
never seen plastersizer used as wall insulation before as it is very flammable. in old houses here we can find sawdust used as insulation, usually there is glasfiber wool and rockwool in later installations.
As a matter of interest, when you do an EV charger install, what paper work, test results etc, do you leave with the customer.
I have just had a Wallbox installed by Octopus Energy via a their contractor and a sub contractor and got nothing which surprised me.
Went for 10mm SWA as it was 30m of cable across a lawn. Probably overkill but future proofing.
It is a pity that I am to far from Cambridge to have asked you about doing it.
Re problem of wall cavities. I like to slide some 20mm PVC conduit through to guide stubborn cables through the cavity as well as protecting them from polystyrene and rodents (maybe). Only problem is a 20mm drill only seems to make a 19mm hole. So I take off-cuts and pass them over my table saw at home, just to put a single 3mm slot in the pipe. This closes up and reduces diam.of pipe when you push it through the wall. Will take 6mm SWA.
I now understand why some people give J it tight . There is something annoying about his voice and way he interacts.. but hey everyone different and the guys done well so well done 👏
Thanks
Drill an oversized hole and run rigid PVC conduit through polystyrene-insulated walls. It's just cleaner, easier to work with, and any future spark will thank you. Horrible stuff.
I have had problems with the insulation beads coming out of drilled holes. If I find the cavity is filled with these I inject foam just above the hole to hold the beads in place drill another hole inject there drill though this foam no problems.
That corrugated plastic pipe from the fan unit to the outside is going to be half full of condensed water soon. The fan and pipe should have been elevated to cause condensed water to drain towards the outside and the pipe up from the bathroom (and preferably to the outside) should have been double walled / insulated.
no problem in the Netherlands with the insulation. we do not use this type of insulation material for cavity walls.
sjongejongejonge, I am always amazed at how much difference there is in electrical installations in different countries. in the netherlands it is out of the woods that individual conductors are installed without protection. keep up the good work guys.
Why is Jordan, sporting a Thomas Nagy Beard ??
😂😂😂
nice to see you back on the tools jordan
Not keen on mounting a cu and henley block on the kitchen cabinet, just causes issues if changing the kitchen
great work on the tools , with Jordan and Lee and no verbal direr
Always use adaptorflex through the cavity
Meggar leads are meant to be plugged the other way on the tester, so the right angle connection is pointing towards the front not the back. Something to do when they are pointing backwards you can put pressure on the bends forcing the internal connections apart causing false readings.#
Or so I have been lead to believe
Interesting thanks
I’ve only fitted two EV Chargepoint’s. One was a Hypervolt, and I was assessed on it as part of my yearly NICEIC domestic installer assessment.
My assessor said I should have attached a document from Hypervolt to the EIC for 722.411.4.1 compliance. As I didn’t do this, he recorded it as a non-conformance. I have asked Hypervolt for guidance but they haven’t come back to me on this as of yet.
Just wondering if you guys know much about this?
Thanks, Jim
Very strange, we have never done that. I hate how every NICEIC assessor seems to have a different set of rules
Why not install the new board with 3 circuits initially, the ev charger and two feeders to the old panels, then take out those feeder circuits when you move everything out of the old panels.
Cable tongue is an absolute god send. I love mine 👍
I love those dummy dimmers, i had one in my old house and it used to confuse the hell out of people.
When Jordan was looking through the window it reminded me of Harry from home alone when he is peering in looking at Kevin Mcallister 😂
My distribution board connecting over 50 years as an Industrial electrician was quality,if you want a sample of my work go to Norfolk and Norwich Hospital where I connected a few
There’s is such a massive problem in the trade at the moment.
I’m charging clients £550 +VAT to replace there consumer units. Lately clients have been responding with I’ve been quoted £150..
it’s impossible. How an earth does that even add up. It’s getting worse and worse. I have had to lower my prices massively and even with the reduction people are still saying they are getting quoted half the price.
I don’t know what is going on but what I do know is that it’s messing everything up.
Have you been affected in this way at all?
Hello, why didn't you use a bit of 32mm conduit through the wall skins to prevent the contact with the cables? Regards David Rayner
Thanks for the Unilite code Jordan, bought a few lights the other day and the 25% comes in handy. Especially for a some company like myself
Happy to help!
Jordan’s Dutch Saying is … I need some Pringles ! 😂😃🎄👍🏻
Haha
I would have used a shorter drill first and then the great long one, less chance of it buckling.
Never understand why they do it like that.
How did you isolate the circuits to change the Henley block?, don't expect you will answer this question.
He's an accredited domestic installer; many DNOs will officially allow such people to pull the main fuse. Even if you aren't, at the end of the day, safe isolation trumps all, and if the only way you can safely isolate the installation is to pull the main fuse, and you need to isolate the installation to do the job (e.g. board change), no DNO is going to ding you for that in practice, as long as you inform them so that they can come and inspect it after (to verify you haven't bypassed the meter) and seal it up again.
@@aaronmdjones well if that's the case why don't they just say that, but is it the case the dno don't like it being done and that's why they never tell you how they safely isolated the circuit
I never recommend plastic vent pipe or anything that isn’t sooth wall metal pipe. Huge reduction in flow from corrugated pipe
Henley blocks with exposed copper seems like a bit of an issue more than the usual run of exposed copper - that’s a cat IV, 60-100A fused electrocution hazard, not “just” a cat II or III one with RCD protection. Yikes.
Put a piece of pvc pipe through the wall and then put the cabels through the wall so the cabel don't touching the wall cavity insulation
Should a conduit be installed through the cavity wall to keep insulation away from the cables?
Ahem .... sorry if it appears I am being a pedant BUT the 0.18ohm you said was the Ze wasn't. The green croc was attached on the earth bar which had circuit CPCs on it and the earth tail in the board went to the MET which had the main bondings and other board earths in place, which would have brought down the resistivity due due parallel paths. It is more sort of a Zdb wouldn't you say Jordan? Other than that I enjoyed your vid as usual. I love my 1741+ and glad to see you like yours. Will they let you keep it?
Yes observer's the migration ,the insulation on the ring cables was bubbly and the polystyrene balls embedded into it as well.
11:44 yep, drain all the customer's insulation :D
I will never understand why the UK allows those horrid board placements. There is no other country in Europe where it's legal to supply power to an installation like that. It's "either get a proper mainboard or live in the dark". And yes, doing it the mainland way starts around £600 for the mainboard installation, but then it gets done right, it's properly accessible and safe, and you don't have to chase all over the place looking for different boxes because everything is (and has to be) contained in one place.
Why not have the charger for the car nearer the car, to the left of the company fuse, else too close to crosswise wall? Fire-resisting foam will sort out the insulation problem. You are so right I hate lounge-lizard tasks, doing it is better. However you cannot get the staff and to train them slows work. Those you can get want mpre than poorer folk can afford.
Was that Henley block fitted by the old school electricians who cared about their work or the "kitchen fitters"
All on a 60 amp fuse... wow what a mess. I do like how metal CU, metal boxes, all metal but then install these in particle board / wooden cabinets that are plastic coated! So if there is some sort of event you wouldn't know right away because its enclosed. 💥🤦♂🤷♂ I assume they put a bunch of flammable stuff in the cabinet as well.
Where do you stop though with non-flammable materials? The CU's not meant to be fireproof but to contain any fire for longer than plastic.
@@tobysherring1369 I completely agree with you. Its just funny that they were steel, wood, plastic and then back to steel. Here in the US, a good percentage are located in the wall cavities and are flush mount. That is the norm, unless mounted in a basement and then put surface mount on concrete basement wall for example. There are a few cities like Chicago that require all residential wiring be located in steel conduit throughout the entire house. Luckily here in Texas its just in the walls with NM-B (twin and earth basically).
I am wondering why you never use plastic pipes??Its better outside because off the straigtnes off the pipe.Those plastic bals cant get into contact with the cables etc.etc..Look at that white cable outside!Thats not right!Better with a pipe!Everything is better with a pipe!
Hi Jordan, who makes your winter jackets and fleeces??.
This is known from old computers that were stored in polystyrene with cables. The enclosed cable often reacts with the polystyrene.
As an non native English I am getting confused about stuff and staff. English is crazy.
Hi Jordan! I'm Dutch and your 'Sjongejongejonge' is absolutely brilliant... as if a Dutch person is speaking, perfect accent. So funny. Love your videos, even though I'm not a sparky, they are so fun to watch. Keep up the good work and cheers to your team!
Haha awesome thanks

Hi guys, I really enjoyed this video. I’d like to say that I’m enjoying watching lee’s videos I really think you have a great team. Keep up the great entertainment and merry Christmas. Kind regards Robert in Australia
Merry Christmas Jordan & Staff
Please wish all the staff a Merry Christmas for me. Love your vlogs.
I really liked the Megger MFT1741 plus, in the process on starting out on my own and need a multifunction tester can you suggest one to go with - I have seen you use several different ones recently - can you do a comparison video of options?
Am i glad i live in the Netherlands!Were we have one cupboard for everything.Gasmeter,watermeter and electrics,etc..😁😁 But we are special because we also switch the blue wires..Not just the brown.
I’ve just had Insulate Britain on the phone Jordan and they are not happy 😂
Nice to see Jordan back on the working videos rather than in the office :)
What size drillbit was used to bring those 25mmx2 and 16mm earth through?
Don’t you use any conduit or sleeve going through the wall ?
I am quite impressed! I do see what appears to be service entrance equipment (U.S. term) coming into
a cupboard at times with no metal enclosure.
I have to ask, honestly… how many times a month do you get a shock? Personally I try to keep it below 3.
Just another thought, curious to know why you haven’t invested in walkie-talkies when more than 1 on-site?
