26:10 the laptop has a magnetic sensor to detect when the lid is closed. you can change the settings to do nothing when the lid is closed or when your watch is near it
Hall sensor
Blanking the screen tends to be hard wired - setting it to 'do nothing' just means it won't shut down or go to sleep.
To be clear, the apple watch has a strong magnet that keeps it connected to the charging puck. It's not just because it's metallic.
Was just gonna say that
Beat me to it :)
Hi Tom, I don't know if you still read the comments. I used to work as an assistant manager for a wholesaler, and I loved the relationships I built with my customers in spite of enormous mistrust within the industry, I really did my best for them! Eventually one of my best customers approached me and asked me if id like to work for him. Consequently, at 32, i'm now an apprentice, attending college as well as enjoying diagnostics, testing and electrical installations at work.
I've been watching your channel for a couple of years, I love the pragmatic and real approach to work that you shamelessly share, and you were a significant component in me taking this massive leap of a career change.
Keep up the good work, and thank you very much.
im in the process of doing something different at 35. I'm starting my courses this year to get my NVQ lvl 2 and 3
ben howard Well some mate,all the best.
@@gmeadowcroft84 nice one mate, best of luck
@@jasonantigua6825 thankyou mate!!
ben howard you’re welcome
Dear Tom, this is one of your best videos so far - I love the chatty style and covering all those old chesnut subjects and the way you do it, the dry cynicism and enthusiasm mixed and jumbled up and sorry to hear about your dear old bike. This was a great video. I wish I had a toughbook but I use lenovo think pads on jobs always have, second hand too, not too much money to replace. That looks like it'll last you well. You are indubitably the master of the genre, this was a nice video, and a nice length too. Thanks very much.
Nothing like doing it yourself, single handedly, sometimes in the dark too.

Same thing with intuition: If it smells like shit, if it looks like shit, if it tastes like shit: spit it tf out.
It’s good to see an electrician with common sense these days instead of quoting regs and putting fellow electricians down.
Cjr electrical...
Lol Poor Chris
The Laptop is thinking the cover (screen) is closed.. magnetic switch. Love the Channel.. Sparky from the US. Thanks for sharing your craft
If you are a jobing spark and are not well practiced at working live, you could be in for a shock. When I trained in 1980 it was part of the course. Being able to use the correct procedures when working live is as important as understanding the isolation procedure.
John Davies Or just pull the main fuse out like any normal electrician does...
@@uplightuk8924 yea cause that happens much lol as if dno would be happy
I agree with the insulation resistance test at 250 volts then 500 I do the same just incase somethings plugged in that was missed and cause damage to any electronic appliances
Paul Tipton volts
@@jakegamble7743 yep I stand corrected👍
I remember watching this channel about 2 years ago. This video randomly came up on my feed after all this time and I'm delighted. I get to learn a bit and have a laugh at the same time.
Perfect timing just about to have a poo
Liam Morris literally laughed out loud because I’m watching this on the toilet 😂😂😂😂
Same 😂
tmi!
Hahaa same
@@richardwesson9651 at least half of us are in the same boat lol
Great stuff Tom....best luck getting the big job
Link line and neutral together and test to earth stops false readings from neons and lamps it's in guidance note 3
doesn't always work
Like your stuff.
Beer and peanuts nothing..
But still sitting here not working, watching you work, is good stuff.
The company I worked for was fitting those boards back in 1965. The theory of the twisting 7.29 was to stop the screw cutting the wire. We didn’t have posh torque screwdrivers back then.
I have literally no idea about pretty much anything you talk about... but it's fair to say I have become obsessed with watching your channel. Keep the videos coming mate. 👍
Saw you on Monday Tom when I was driving into London.
You are right about the level of danger involved in live working. There is danger, but it can be managed if you are careful. One of the more dangerous aspects of the work in the video was the refitting of the covers on the Henley blocks; one slip and your fingers might have been inside the block! A dab of superglue on the end of your VDE pliers would glue the cover to them for long enough to offer up the cover to the block and do up the screw.
Wear novax gloves
Hello young man re safe isolation keep on doing what you are doing, unfortunately common sense ain't so common I have been sparking for 40 odd years and I have alway worked like you do, using common sense to work and stay safe,
I think the the Panasonic Toughbook has a magnetic sensor in it for when you close the laptop that the screen would go off.
This is why.
Th enough book I had, had a reed switch near the same location to detect if it gets dropped.
I think its there to park the hard drive to step a physical knock wrecking the hard drive.
Little point with sad hard drives
@@BillyNoMates1974 Yeah. Sad hard-drives are the worst. They just keep going to sleep and don't really do much :(
stuck in a cupboard being tortured eating infected grapes... yes I quite like this suffering Nagy haha
Great effort filming in that sock drawer!
Very enjoyable vlog tom👍🏻could u do more of you doing testing
Safe isolation is all about a combination of competency and being in control of the situation.
Wow, you actually had me pegged... "sitting there with your crisps, beer, peanuts..."
You can tell what your up against when you see the first light switch in the hall way what the banter is about to be!!
Neat coiled Earth connection to the surge protector but this is effectively a choke and may increase earth impedance preventing the surge protector performing effectively. I would think a short straight wire would be preferable. People may argue that at 50 Hz it is not an issue but the intention is to quench the rapid rise time of the surge ASAP so low impedance it desirable.
Bought the exact same laptop a couple years ago, love the battery life on it.
Hall effect sensor in the lid to switch the screen off when the lid closes can be switched off in the settings. Another great video 👌🏻
I have to say I find you very Entertaining to listen to and watch. As a fellow spark I can tell you know what your doing. I’m trying to get pointers about house work to be more efficient because I’ve mainly done Commercial and Industrial.
Watching this in the US hearing you talk about ring circuits makes my brain hurt! I love our split phase 120v systems here, so simple and straight forward!
Until you get to high leg delta supplies. That'll make your head explode!
There's a reason why only countries following British wiring practices (and that's very few in the grand scheme of things) use ring final circuits.
Ring final circuits were installed because there was a copper shortage at the time and have been used over since but now we are starting to go the route of radial circuits also that is why all British standard plugs have the fuse in them as the ring final circuit is protected via a 32amp breaker splitting the load between 2x 2.5mm conductors and the largest fuse item that can be plugged in is 13amp.
I know of one house in SE London that has a 600 Amp 3 phase 400 Volt supply fed direct from the substation, but the they do have two 150Kw Tesla chargers installed in their garage!
CrazySparkie63 fuck me!!!! 200amp per phase?!!
It’s the magnet from your watch strap. It happens with most laptops but the sensors are usually closer to the display for example the top left of the keyboard on the MacBook Air. It is also how the display knows when to switch off.
The reason your display will turn off when a magnetic object comes in contact with that area is due to there being a reed switch in there for when you close the lid. It’s a sensor to indicate when the screen has been closed to put the pc into sleep mode.
the screen turns of by a magnetic sensor and its probably magnetic to keep it more rugged and not having to have some sloppy mechanism that needs to be waterproof
Nagy is in tune with electrical field of the house ! self-calibrating ;-)
When I went to high school I went to a technical one that had Tafe too, one of the reasons was the electrical trade teacher, he was a good friend of the family.
But now getting to the good part (and no it's not blowing up caps which shut a classroom for awhile, which was the first thing we did there)
I walked pass the classroom and was asked to come in and show the Tafe students how to wire up a hole house (small cubicle that had 5 circuits that was ment to be like a house)
My father did house and industrial and so I was trained early (lucky too)
The teacher made the feed in live and so I had to wire the lot live (this was fuse wire boards and almost 40 years ago)
The students laughed as I was 12 and they was over 20 but I put them in there place so quickly, the best was when I did a test as I just plugged a light in and it worked, they realised I did it all live and didn't get shocked once.
As you said use insulated tools and your head and as I was told, always assume the line is live no matter what, I have never had a at fault shock.
I also pitty you for the small spot you had to work in and even try to film in but you did great thanks for the video.
Hi mate I'm not electrician but I love watching your videos keep them going mate 👍
24:12 BOSCH speed bits all day long, munch through timber like a hot knife on butter 😍🤤
Good video don't think what others say work safe and in your limits and the job a gooden
Mind the spiders, Tom.
Tom knows no fear: "OK chaps, we're going in".
Got sustenance, can stay in here for hours.
Tom worked and worked, and scoffed and scoffed.
Trouble is, his "food baby" got so big, he couldn't get out.
We think he's still in there now.
It's the magnet on your watch strap the though pad ,has a sensor to shutdown the screen when closed to save power
Become an Electrician they said...fun it will be they said.
Cleanest trade out there they said.
Rewarding yes, easy no
@John Smith and plenty of holes in you're knees from nails and screws 🤬😢 oh how I don't miss roof spaces 😋
Dad.......there's voices coming from the cupboard!
I also quite often disconnect from the Henley blocks, but you will often find the screwheads to be 3mm hex. My preferred brand is Knipex 3mm VDE as it doesn't tend to chew the heads up on over torqued screws as a lot of other makes do!
magnetic megger... now there's an idea!!
I’ve got the Metrel multifunction tester that is magnetic, had it quite a few years now, comes in handy at times but is also a pain for stuff sticking to it.
I've got a sore neck just watching you in that small cupboard.
you Sir are working hard.
And that’s why we have “Insulated” tools!
It was quite a coincidence that every installation that needed to be isolated over my entire career, the cutout fuse seal was always already broken, and sometimes, but usually only when I needed to replace tails, the meter seals were also missing. Very strange, but entirely true.... Of course I did my duty and always phoned the REC to let them know it wasn't me that removed them.
Hi Tom, love the channel. its interesting and entertaining. I'm not a spark, i'm a kitchen fitter so obviously a lot of the tech stuff you talk about goes over my head, however did you know that a half used bottle of orange juice in certain conditions, can be explosive?! I found this out....severe brown trouser moment that was!
Keep up the good work.
Very tight squeeze Thomas
My Festool case doesn't make that noise....... Ya tubby bar steward. :) Thanks for the upload us usual. :)
Fully agree with your sentiments Tom,... there's the theory world and there's the real world..
Good video bro 😄
Flat bits - Bosch self-cut speed, can’t beat them Tom
I wasn't claustrophobic until I watched this!! 😁
That was always my least favorite part of running data cables and installing network hardware - working in tight quarters. Gets old quickly as you said. Finally decided to change jobs after falling off a ladder.
I like what you did with the van
Seems positively huge compared to some of the cupboards I’ve had too squeeze into.
Massive cupboard the prefabs up my way have the smallest cupboards ever then you have the gas meter to contend with also
The thing I love most about your Videos Tom is all that English slang lingo I pick up..
I mean sure, seeing an electrician doing what you did like 15 years ago in a different country is a plus (fckin interesting as well), but nothing beats learning new ways to use words =D
Well if Harry Potter needs some work doing then your the man..😁
Like the comment
I thought of Harry Potter as soon as he got in the cupboard haha!
You haven't got a choice but to work on the board while it's live in certain situations. You're an experienced sparky Tom so yo know what you're doing, ignore all the negative comments & keep doing your thing 👍
It's the hall sensor under the top of the casing when it detects that there's a magnetic object in the vicinity, like the magnet that's used in the charger, it's causing that hall sensor to go off and sending the command to windows to turn the panel off.
tomas your are a topman and very down to earth I like your stile and humourus
Arh Tom cheering me up. 😃
The only thing I think I'd do different is a bit of dielectric grease to keep the connections from corroding. It's a good mitigation for harsh environments like by the beach. I used to be a general contractor and encountered this problem where the wires would rot out of the breakers. The grease stopped it happening flat and didn't hurt conductivity at all. So if you find yourself near the coast or any other harsh environment a little dielectric grease will save you a lot of headaches later.
magnetic sensor. there will be a magnet in the lid and this is used to shut down the screen when you close the lid.
In Canada, most main residential panel have the mains under a separate cover so if you turn off the main your bussbars aren’t live
Great job again like always
working on live fuseboards: do a risk assessment, (even in your own head is fine, there's no requirement for it to be written down). If the board looks like a disaster, i pull the main fuse. (puts worm can opener down). If it's just a quick look... leave it live.
Here in Aus we have system where our service fuse has a protective sealing cover that goes over the terminals the supply authority seals that and we can freely remove the service fuse and de energise as we need. Also for pricing larger jobs I use a price per point method.
Thomas im a chippy and by far the best spade bits are the dewalt extreme ones. Chippies give drill bits hell and iv found they are the best. I used them on price for drilling mortice locks out the last ages and they a the easiest to resharpen 👍👍👍👍
I have a CF-19 and I worked out the mechanics behind the way the screen turns off/laptop thinks you closed the lid. In the lid at the top right (I think it was the metal locating pin) there's a weak magnet or piece of ferrous metal (I honestly can't remember which right now but my gut tells me magnet) and a hall effect sensor in the bottom right of the body of the laptop. When the hall effect sensor detects a change in state it tells the motherboard if the lid has been opened or closed. The hall sensor will go either high or low on it's signal pin telling the motherboard open or closed. Your watch either has a magnet in it or has ferrous metal fooling the laptop into thinking the lid was closed, under power options in control panel you probably have the setting 'when lid is closed' set to 'do nothing' this is how I have all my laptops set as I don't want it going to sleep every time I close the lid, which is often.
Hope you understand that but I'm sure you will :)
Another great vid thanks for us that are still learning 👍 if you find two circuits in a 32amp and discover it's not a ring (rfc). what do you do split and put each leg on it's own 16amp or keep both legs in mcb but reduce to a 20amp?? Cheers
I have to say I don't really understand the spark jargon, I think I tune in for 'the world according to Tom' and it's good!
'The world according to Tom' - i think this could be a spin off series...
When working live it’s brown to brown and blue to bits
In those Lucy blocks, were you removed the cables there should be a plastic insert to take the smaller cable with no exposure, if you slide it out and flip it round it’s then a blank.
Another great video. 👍
Tom, get yourself a GoPro and record in POV! Completely hands free and space saving!
Hahahaha loved the laptop bit mate 😂😂😂 you clever bastard .
Dad........there's a man in the cupboard making a movie!
Popcorn is the only thing to eat during your excellent videos.
tht actually one of the more accessible panel disconnect ive seen in a while from you UK sparks you dont need a ladder or have to crawl on your belly to get to it
Isn't the most important thing the radio Tom?
Always pop the radio on before starting 👍
No crisps.
No Beer.
No Peanuts.
Immense enjoyment.
Another good 1 Tom
Yes a new video !!! How’s your Thursdays going ???
There will be a hall-effect sensor I imagine and a magnet in the screen so that it turns off the display when you close the lid. Perhaps there is a magnet in your watch?
I would love to see the test sheets of all the people saying you carnt work live
9:26, a non-sparky here just because I love learning about juice!
8:17 nom nom nom
love it lmao
Do LN to earth as a good guide on insulation resistance and note it as a limitation ,great content as usual
This guy never has a lunch break
Intuition isn't some built in, magical thing. It's a function of time and experience. I've never played a day on a piano, but if I had some intuition about it I could be the next Bach. New sparkie's don't have that intuition yet, so the regs are needed. Until we can just upload experience and knowledge into our minds then there will always be a place for regulation and requirements.
my dads fuse box is old and has one part protected with a RCD and the other part just protected by MCBS.
I take it you installed new cables too : )
IrishHitman79 Where did he join them. Wago in trunking ?
@@AndyK.1 I shouldn't have said anything....
Depending on size I use electrical estimator, but if he will supply parts what you said makes sense. London ~£300 day (with the mates your day rate builds up a bit) X 6 weeks (5days) X 3 guys £27k + bit of fat...
You're always Mr Grumpy at the start of your videos but become smiling Tom at the end. Liked the way in which you did the safe isolation; seems highly logical and safe.
i think there may be one or possibly two people who disagree
@@thomasnagy with what, Tom? The grumpiness or the safe isolation?!
That's a hundred hall sensor comments read 😀
Hi thanks for your cool video's my Q is when you put the security MCB before the RCD where do you connect the live and to which bar do you connect the neutral of the usually they will trip out
Another quality entertaining video.....😁📽️👍👊✌️🍻🏍️
Sounds like you need to go higher than 30k for that club job! More like 40. 10kA RCBO's and all that containment. 3 blokes. Parking/Congestion. Emergency lighting, fire alarms etc. soon adds up
