How to wire an rcd according to regulations?

Tricky one really.

The only other method would be 2" galv trunking but that would be a royal pain.

The only floor boxes i have been involved with were in a 2ft x 2ft square modular suspended floor with the boxes cut into the square where needed.

All cables run in kopex.

To be honest, if its a new install, then there isnt really any other way than using the trak.

I have seen it so many times where twin and earth is used and tie wrapped to the posts, also seen it in twin and earth on tray, cant think that is a lot better as you have more chance of walking on it on tray...think i will start a new thread

Good man.

Ah yes you could be right there, as most RCBO's are only single pole and so therefore, without the flylead, the neutral could go to earth with the RCBO detecting it.



Most RCD's are double pole, so there is your safe isolation.

However, the use of an RCD as a main switch is not a good idea with regards to nuisance tripping.

Hence the dual RCD boards.

Sorry Jason, I missed out if the rcd itself then required replacing due to becoming faulty at a later date.

I'm sure I've seen really old Square D rcbo's without earth fly lead. I'm talking about black and yellow BS4293 ones.
