Ok, not dear old Delroy....
I like Nick, and he's just kitting out this new space, but there's a slight distraction that I might have dealt with before making the video....!

I have seen a few where he's made some cock up's and had to go back to sort it out, The last one was where he didn't know that he needed to use a rcd for TT sub main.Bundy seems nice, in terms of his online content (which is all I can comment on), it's pretty boring. He seems to be doing well for himself though
Bit of a chancer in reality imoI have seen a few where he's made some cock up's and had to go back to sort it out, The last one was where he didn't know that he needed to use a rcd for TT sub main.
His work is not bad, but like Cjr he's not yet well versed with the regs.
There is no absolute requirement in BS7671 to use an rcd on a TT system."Did not know he needed an RCD for a TT sub-main" that is horrendous.
You have to meet disconnection times... we all know on a TT most often the way to achieve this will be with a RCD. I guess the point @westward10 was making (playing devil's advocate I think) was that the regs don't explicitly say "you must use an RCD" ...Not even on a sub-main where you have not exported the main board earth?
It gives options with rcds being the 'preferred method'.You have to meet disconnection times... we all know on a TT most often the way to achieve this will be with a RCD.

I should have said "He didn't know he should have used one as, he had little choice as it wouldn't have met the requirements, instead he went home happy with his finished install then had to go back after he was told and install one.There is no absolute requirement in BS7671 to use an rcd on a TT system.
Preferred method or most practical method?It gives options with rcds being the 'preferred method'.
Usually a 100ma s typeIn most of Europe its an S type 500 Mah up front, is that the same in the UK?
How would a RCD achieve this?The main function of the 500ma RCD is to turn off the electricity if the consumer tries to pull more than their paid for tariff,
Domestics Rock !!I've met Nick in person he's a nice guy very down to earth, watching his videos I think he does a good job but he's very much a domestic domestic electrician, kitchens, rewires and that's about it
Is that on the 3 phase incomer acting as a main isolator as well ?This is the CU I inherited when we purchased the RCD is under the CU:

In that case, you have a RCBO, not RCD. A RCD only reacts to differences between current out and current in .
