You are so nice to James hopefully he will look back at these days and think he had a great teacher!
True any one is lucky to be Chris apprentice
He doesn’t get angry at him for doing stuff wrong just teaches him how to it right and encourages him
Starting off I had to graft like fuck and do everything perfectly and the guy in charge of me still didn’t pay me properly! Some apprentices don’t know how good they’ve got it
@@PJOffler Until they get it bad. Then they'll know...
James has more work ethic than I do. I've taken my birthday off as leave for longer than I can remember.
James’ enthusiasm is contagious 🤣
Hahaha.
The 3 refers to the energy limiting class, nothing to do with number of times it can be reset.
Yeah. It would a terribly designed breaker if it had to be used dumped after 3 trips 😂
hager says on their website that the MBN116 (widely used in Germany) has a lifespan of 20000 mechanical switching cycles and can handle 4000 electrical trippings. So the "3" sounded a bit low for me..
Thank you destroying the wet dream of all electricians:)
BTW: Such machinations are not uncommon in other areas. See the lighting industry, agreements on service life and predetermined breaking points.
An of course you are right:) From the B32 5932 data sheet:
RATED SHORT CIRCUIT CAPACITY ICN
6000A
SERVICE SHORT CIRCUIT CAPACITY ICS
6000A
When backed up by a BS 1361, 100A fuse, then
the breaking capacity of the MCB is increased to
16,000A.
Energy limiting class: 3
That would be a heck of a business for suppliers if the '3' described the number of trips allowed!
It's the energy limiting class for I2t which describes short circuit current which needs to be known to assess cable protection during design.
This is a bit like Artisan Electrics thinking that the little plastic bit at the top of pull cords is an isolator!
You should know this stuff!
Nice vids my friend.
Those switches are brilliant 👍👍
Brilliant work Chris and James and thanks for the content stay safe and take care
It’s good having an apprentice to keep you company 👍🏽
Great video this was excellent. Detailed and lots of tips for apprentices.
Always nice to see you thinking about the next sparky who has to do work in the future 👍
Hi both. I must admit I’m sold on these switches , and doing away with the PIR is a bonus. My friend is building a new house and has put switch wires in , but still intends to use this type of switch because there so controllable. Professional work from you as always , my best wishes to pair of you 😃😃👍
The 3 is the energy limiting class. Someone was pulling your leg 🦵 mate
Cracking video Chris and James. Enjoyed this one!!
Love watching and learning from your vids
I don’t think I have heard you laugh so much Chris, such a happy chap on the vid. Happy birthday James
Happy belated birthday James! Nice little gift for you :)
Thumbs up mate.
For this video and your socks.
This is becoming the highlight of my week, cjr posting, well there is naff all good on TV this good🤣 electrically speaking!
Top-notch video, keep it up.
Don’t start again on the iPhone calculator James. Just swipe to the right and it removes your last number 👍🏻
I'll remember that 'ryan' when I'm pushed for time.. (digital trap victim)
How about 2k thumbs up James gets some fun socks. Those wireless switches are very handy and quick.
Happy Birthday James
That van! It would drive me crazy. Tidy it man!
Mine looks the same at the moment TBH, too many trips to TLC for this and that. (usually the van floor is empty, i'm not the only guy so don't have to fill the van with power tools like most guys, most of my tools/normal supplies live on the racking or in stackable boxes). But having the relatively emptyish van, I get the weekly orders to pick up from various wholesalers on friday (or monday morning if i wet the bed). By about wed or thurs, looks like a tip. This week's already booked up for lots of stuff so there's about 400 pounds (in weight AND value) of stock in a pile... lol
The three is the energy limitation class according to EN 60898, or here in Germany the VDE 0641. This defines when the MCB switches off, class 3 means in the MCB switches off in one third of a half period of the sine wave. Class 2 switches off in a half of a half period of a sine wave. Class 1 is no longer available. Class 1 switched off when the sine wave reached its zero point. This is to spare the contacts, because then you won't have any arcing. But in case of a fault that will stress the cables much more.
Another cracking video, it must be nice to have someone to help you out.
Blaming deer lol, that’s what everyone’s van looks like on a Friday evening. Don’t need to make excuses 😂
More likely to have been doing doughnuts
Great work I'm new sub and training to be an electrician... I think your good boss and fun,patient guy
I would love to see tests like this on American systems! Nothing gets tested by our inspectors quick look, and they walk around with a outlet tester just to see if it’s wired right,,, if it’s Friday then you might just get signed off on!
The 3 in the box is the energy limiting class. Which in this case is class 3. Something to do with I2t rating.
It's in the MK MCB catalogue. but not being a sparky it means nothing to me. :)
good job James
Can only go one way.......No the other way🤣🤣
Ive found that most wire free switches play up after 9 months/ 12 months so it’s a last resort for us
Happy B-Day Stretch...
My understanding was that a cooker circuit is a final circuit not a distribution circuit, so would be a disconnection time of 0.4 seconds socket or not.
Thanks for the great content, keep it up 👍
Yep I think you are correct. I t did used to be the other way but was changed
The 3 in the box is the energy rating.
He's a good lad! James ain't too bad either 😅
0:46 You had a *David Brent from the Office* moment
Ohh this cracked me up 😜
Nice one Chris and james 👍👍 them quenetic switches are brilliant !
They've been a game changer for us mate... lots of 30's-40's houses round this area. Often they've been hacked about and patched into... often customers decorate, THEN find that the 1940s TRS (tough rubber) wiring is ... yknow, not to standard anymore. So long as we can get under floors... offering them quinetic receivers with standard looking switches (a grid module in a single or x-way grid frame) makes them relax. For what Chris did here, the standard paddles are awesome. We sometimes suggest them for entry/exit doors, because you can operate them with an elbow or shoulder when your hands are dirty or full.
Done several complete houses with banks of quinetic receivers somewhere accessible. Usually a cabinet under the stairs, easy access to under the floor upstairs, and a cabinet in the loft. The receivers are damned cheap anyway, but when you add on the time saving, the lack of making good, and the number of possible options.... a master switch that turns on/off all the lights, simple sir..., want to turn on your porch light before you get out of the car, there's a key fob remote for that... it becomes a no brainer!
@@TheChipmunk2008 so I take it as long as the receiver like you say is accessible say (in a loft) then jobs a good en. Bloody genius idea, and are the switches them selves battery then 🤔 cheers mate
Kinetic energy when pressed
@@Cjrelectrical Yes what chris said.. the name says it all, the pressing of the switch generates the power needed to activate the transmitter. The receiver of course has power all the time it's needed. To me that's the MAJOR selling point over other brands of wireless switching. No pesky battery replacements, even if they're only every 3 yrs and really easy lol
Installed to date, several hundred of them dating back to when they were new (5-6 yrs i think?) had Three callbacks. two were my fault. one was siting the grid transmitter in an earthed metal box with a metal faceplate (normal for an electrician but any Radio guy is screaming faraday cage. it only managed 30ft range. Which was amazing given it was in a grounded steel box!). The second was similar but distance was already marginal, and the receiver got sited behind a large stainless steel fridge. D'OH!.
The third was an actual failure, and was the receiver. TLC replaced it in 10 mins
I always double over my conductor, single or multicore unless its two or more conductors in a connector, extra smarties please :)
James. If you’re working over a sink or near one, in a shower or a bath on an electric shower you will love yourself if you put the plug in the plug hole. I guarantee it.
Very good tip.
Did that and mum yelled at me... Straight down the bath drain! Was changing the lightbulb and dropped the nut for the cover.
And always put the loo seat down
The house that Jack built 😂
Happy Birthday James!!! 🎂🎂🎂
I like that thumbnail haha!
3 is the magic number 😂😂😂
Where did you get those short link out leads from great vids by the way
Good job ya had the steel bulkhead in the van you could have been wearing a roll of T+E 😀
1.5mm... as a necklace... took casualty ages to figure it out lol. Honestly when he said he hadn't looked in the back I thought he might have taken a dead deer home! (spent too long living in the midwest USA!)
he comes to work on his birthday, now that's a miracle - I think, most people do...
re the cooker switch as there as there is only an oven is the 32amps rcd correct? I have a single switch as well and there is a socket outlet low behind where the oven is and it gets turned on with the single cooker switch so should you have pulled the oven out?.
I squared t is the '3'. Its 'let through energy'. Nothing to do with the amount of trip times. Only, I wish it was, it would be so much easier lol
I love myths. Did you know, when you apply for a loan with your bank, your signature creates the funds? a bank does not lend you 'money'............
Oh shite just noticed everyone beat me to it...
Wish my boss would have been as good as you.... He was absolutely minted, after 6 months I would be left on many a job alone and he was invoicing full payment as if I were fully qualified.
I failed one exam out of 4 twice and really tried, was let go and recession hit, never went back at it but done 4 years at it.
Get him in the funky socks, then you can start having my thumbs up :)
Need a gofundme for socks
Do you get payed for the remedials that you do I.e calking round that socket. Do you just bill them after ?
Brilliant socks mate.😁 Are you going to rack out your van, if so when?🤔
Previous electrician may have been used to a different brand of accessory and just gone into autopilot re: length of cpc outside the sleeving. No excuse for not picking it up on initial verification but i can see how it might have occurred.
Do you find you get a feel for 'yep the Zs is gonna be high on this socket' during EICR's, just due to the feel? Mostly old tenby ones in our area
You can swap birthday boy with James Acaster and don't notice for a while.
The 3 to my understanding is actually th Ics value with the 6000 being the Icn value.
You are wrong. It means "Energy limiting class" = 3. From the B32 5932 data sheet:
RATED SHORT CIRCUIT CAPACITY ICN
6000A
SERVICE SHORT CIRCUIT CAPACITY ICS
6000A
When backed up by a BS 1361, 100A fuse, then
the breaking capacity of the MCB is increased to
16,000A.
Energy limiting class: 3
I think you need to call Nick to come organize your van😆
Did I spot all the lightitng circuits on the left RCD only?
You love an advert now!!
You should get a headband strap for whatever you use as a camera so it's always pointed at whatever you're looking at while leaving both hands free for the Job...
Why does the smoke alarm need to be optical? Genuine question
Sure im late to the party here but i think the 3 is the ka rating that it can take and be able to be used safely again. The 6000 is the rating that it can safely break but it may not be able to be reset.
Crikey! Has your van been burgled or did you roll it in the snow? Add a sock rack when you get round to sorting it out!
he swerved to avoid the deer, but +1 for a sock rack. A DIN rail mounted sock clip would be ideal! LOL
22:33 There could be a good "How many sparks to put on light cover?" joke in here somewhere, but I won't do that. 😜🍺
How do you print your labels
I believe 3ka is what it can withstand with out needing go be replaced but up can withstand upto 6ka without blowing itself too bits but then should be replaced!
@Dark Dreamz it depends on the supply certainly possible but it would depend on the supply could be higher, you would certainly know about it, probably not as bad a lightning strike but I’m not the best at explaining these things technically........🤔
Does the quinetic receiver also switch the neutral, (would it affect an emergency light on a circuit)
Neutral is just a solid link
Yaaas, this has just saved a nightmare rewire 😁👍
3 isn't anything to do with how many trips it can have... It's the energy limiting class rating. Good try whoever pulled your leg on that one :)
When you hit a incorrect number on the iPhone calculator you can swipe left on the display and it will remove it :)
poor accessories, poor zs, poor everything. Never have this with quality , like Hager..:-)
great vid though, keep going with the vids
Can I just ask is the Rcd on the RHS of the DB not undersized? fused at 100A (EB supply) and has the potential for 96A to be pulled! I think its only a 63A 30mA. It's not a criticism but is that not a C2?
Maybe the guy that fitted the rcd actually pulled the main fuse and found it was only a 60 or 80 amp supply and then got the dno to reseal it......just because it says 100 amp doesn't mean so.....seecit all the time
Nope. Maximum demand has to take in to account diversity. And that is only at the time the installation is inspected if its occupied to see how the energy might be used. If one occupier uses gas for heating, then subject to an electric car the demand will be generally low. If the occupier has a gas phobia and went for electric heating it may be a higher demand.
Only minor criticism is that I would have put a 240V warning sticker on that box - given the lack of double insulation. As for the "3", it's class 3 energy limiting - not 3x trip & replace.
I’m sure he was taking the piss about the 3 x trip and replace
Hello, whats the software cert package you use on your ipad?
I certfi
The tails coming from meter are in theory buried within a wall at a depth less than 50mm. And not necessarily in prescribed zone. Should they have been bought surface, not by you but originally??
Being from the United Stated this is very strange to me. The main panel looks pretty small. My last install was a 200 Amp 40 circuit breaker box. Our wire color codes seem more simplistic. I prefer our smaller 120v outlets and switches over the huge ones used there. Interesting though.
Uk is well behind the times mate. Europe laughs at our electrics, it's much more simple in the EU and the fittings are much nicer and a wider variety too.
Hope he got his coffee
what software you using bud ?
those damn light have 2 pins in them that always snap ... the NHS is littered with them ...
That loose plastic box next to the meter with a sensor on the L tail, is the pickup for an old British Gas energy monitor.
Where did you get your link for r1 + r2 from?
Testermans
Can you just these Quinetic switches in a bathroom or are they still not allowed?
Yep you can
@@Cjrelectrical Do they do a momentary one to turn on say.. a timer fan?
You can have one on your shower door if you want
@@Zephieish If you get the one that's also wifi controlled, it looks like you can set a "countdown" from the app, but it's difficult to tell if that's a thing you have to set each time or not. Looks like they're using the Tuya Smartlife system so I'd be surprised if someone hadn't figured out how to properly link them to a home automation system.
how come you don't have any racks in the van?
I don’t drink at work.
New jumper it is then...
with the spotlights has anyone noticed that saxby have made it near impossible to have more than one entry into there lights to the stage were you have to remove the junction box and replace it with something that can like a robus ones, boils my piss especially if the client buys the light your hands are tied so i always reserve judgement until i look at the nick of the Junction box,
Your "proper electrician did this" comment on the downlights made me laugh. I've seen a few diy jobs better than pro jobs
Yes, saw one today on an EICR, almost exactly the same actually, older JCC lights, same style of connector. All done by the tenant (with landlord's ok, tenant is an IT guy). Beautifully terminated, even inside the cover, wires bent exactly to shape and well terminated. Tenant said being used to dealing with Cat6 which is fussy... makes him neat LOL
What camera work, I feel almost seasick
17th edition. (But not amendment 3)
🤣
The MCB the number 3 means it can take a maximum fault load of 6ka 3 times before replace required.
No it doesn’t, Energy-Limiting Classes
Circuit-breakers to BS EN 60898 of B-type and C-type, having rated current up to and including 63 A and a rated short-circuit capacity of 3 000 A, 4 500 A, 6 000 A and 10 000 A, are classified according to the limits within which their I2t characteristics lie. I2t is a measure of the energy let-through by the circuit-breaker under short-circuit conditions.
This is denoted by the limiting class , (3) being shown in a box on the ocpd, it helps designers in selecting devices for the required short circuit protection.
A requirement when you need to know that the K2S2 withstand of the cable can handle the energy let though of the protective device for disconnection times under the stated 0.1 seconds shown in appendix 3 of bs7671, which is more often than not, required to be verified.
As mentioned it relates to the class of energy let through
There are probably 0 tin knockers over there?
You need a megger to get continuity readings while filming at the same time 😂 no need for pressing test every time
Kewtech has hands free I just like pressing the button
@@Cjrelectrical oh really ! I’ve never used one only ever seen you a J beck pressing the button 😃
The kitchen socket with the screws that are too long, would have been better to cut them instead of adding gunk to close the gap.
You obviously don't understand.....the screws are very long because the back box is set too far back in the wall after it had been tiled.....cutting the screws wont help because they will still wobble......
If you get 100k likes you gonna buy James a van
Nice to see you fix up that sloppy work from a predecessor.
I don't understand how a cooker isolation switch counts as a 'point'. Does that mean every light switch, shower isolator, immersion heater switch, etc is a point, not just the actual outlet (eg lampholder, socket, CCU)?
All the messing about with nulling leads and giving them a squeeze - Lord Kelvin must be spinning in his grave. Surely one of these manufacturers can puzzle their way through a problem solved 160 years ago..
Could have got James a new jumper
Blaming old deers for your untidy van pmsl...
Smoke alarms on a vaulted ceilings need to be away from the peak (think about 600mm from memory) so that smoke wasn’t that poorly sited.
Yeah 600 from the apex this was more like 2m
Ok mate, could not tell precisely the distance with the camera bouncing around 😉
I never understand why wiggling test plugs in sockets to get the correct reading validates a "good reading" the terminals in the socket outlets are obviously tarnished and high in resistance reducing ADS times, why not just change all the poor socket outlets, they cost next to nothing, and provide a better Zs and look nicer lol...crazy.
If the zs is still within maximum it’s up to the client if they want to replace them.
@@Cjrelectrical Yeah i get that Chris, but obviously damp and corrosion caused the higher readings, so why not just replace them? they will only get worse over time, and it kind of makes a mockery of your test results at the end of the day?...just an observation ;-)
@@muzikman2008 if it’s within limits I’d refer back to client first before starting replacing items.... might be cheapish item but add them all up and it’s a lot of time and cost for the client to pay for unknowingly. Quick call and give the option of replace or shorten retest period. 👍
So you want to replace cheap sockets with sockets that cost next to nothing.....Duh
5/10 for camera work 😂
Really that high
@@Cjrelectrical My head is still spinning, feel like I've just been on the waltzers! ;-)
