I could utterly wring the neck of our builders that put in 10mm for a shower (that goes unused by everyone who simply changes the mixer tap in the tub) but for some reason put 4mm out to my garage. You know, where everyone wants to put a car charger.
What I find bizarre is why the tables don't clearly state "burried in solid wall" or "burried in solid wall with protective conduit" etc... there are so many instances like that and yet they want to be ambiguous in the....REGULATIONS. Makes sense; NOT.
Wow, this is worrying electricians needing to do CPD to work this out - is this not basic stuff covered during formal training? How many are out there that are sticking fingers in the air 😮
We've got people watching from every stage of the electrician's journey, some apprentices who'll benefit from this at college, right up to the spark who's been doing it for years and not fully understanding it. 😂
Most industrial/commercial jobs we do have the cable size specified by the consultant so no calcs required onsite. I personally verify whats specified, for peace of mind and so i don't loose the skill. Most of my colleges, approved electricians, would struggle understanding this video!!
@@tonywatson1412 I used to be a factory spark back in the late 80's early 90's I'm fascinated by all these gadgets that have appeared over the years to make people's lives easier and their day more productive But the actual hard work and maths that you need to do in order to do a good job is not shown and everything thinks we spend all day in perfect conditions playing with expensive toys and billing huge figures for running a few wires The other day I spent 3 hours running a lighting circuit for 3 time and a hallway in a loft, a job that would have taken me 20/30 minutes as a first fix but took 3 hours as my mate, whos house it was, wanted me to explain every single connection and how it linked to the next light/switch/room Anyway, it was hot and itchy and I didn't need to get that way
It's more for apprentices, someone needs to teach them how to do it and it's nice to always have a video to reference later down the line compared to trying to scribble down notes in class and hoping you got all the correct information

Nooo please don’t do these kinds of videos. Your videos go all over the world and every place has different codes and regulations and rules that govern different awg wire sizes I don’t wanna go to a house because some kid blew himself up because he didn’t size the cable properly. Orr make my job even more of a headache because I couldn’t find some other dumb thing he did in the house. I studied this and worked a lot of years in this trade. This was irresponsible to post I’m gonna have to unsubscribe because of this. 😢
Trust me if they follow the British standard for cable sizing nothing will blow up / burnd down because the standard is extremely cautious, at the full load rating the correctly sized cable would not even get warm. That being said people should still only undertake work to the local codes/regulations, and be qualified/competent to do so .
Thanks for the vid. This stuff was covered in a basic electrical course I attended but nice to get a refresher.
Future proof it 10mm for everything especially led lights

😂 Definitely not over-engineered...
Do they do Wagos that size yet?
LED's don't use high current at 230 volts...
10mm? You cowboy! 16 all the way for me... 😀
a 9kW electric boiler, a mere £2.70 an hour to run.
Well, every silver lining has its cloud! 🤷
Is the answer; whatever is lying around and can get through the hole?
Extra points for running mains over CAT5/6/wet string...

Always use 1mm singles, cheaper that way.
1.5mm2 is the smallest you can use, according to regs.
@@klarnorbert its 1mm² minimum for copper, 0.75mm² for flex, 0.5mm² or even 0.1mm² for some signalling cables, Table 52.3

@@johnaphone and this is what's worrying! I guess then having repeat training on basics is what's needed - I wouldn't consider it CPD however!
Ugh boring maths 😕
No fancy things that make things exciting but only comprise 2% of being a spark
eh. ?

But the actual hard work and maths that you need to do in order to do a good job is not shown and everything thinks we spend all day in perfect conditions playing with expensive toys and billing huge figures for running a few wires
The other day I spent 3 hours running a lighting circuit for 3 time and a hallway in a loft, a job that would have taken me 20/30 minutes as a first fix but took 3 hours as my mate, whos house it was, wanted me to explain every single connection and how it linked to the next light/switch/room
Anyway, it was hot and itchy and I didn't need to get that way
😂 We're trying to please all the people! 👍
It's boring because you can't do it.
Didn't pass GCSE or O level Maths in school?
@@deang5622 I stopped being an industrial spark in 1991...
Who is the real Joe Robinson. Is he bearded or unbearded ? 😕
He's Schroedinger's Joe. He's both bearded and unbearded until you press play...
Are you catering for diy now , if a spark doesn’t know how to select the right size cable they should get another job 🤷♂️

I don’t know if you’re being ironic or just daft? These are training guides for people learning the trade.
