TT install with metalclad CU

[Engineer54]

Here in France, where almost every installation in a TT system, EDF provide a 500mA main S type RCD and anything after that is the clients resposibility. Metal CU's are acceptable but as has been said previously, glands and gromets should be used, but this is not always the case, depending on the electrician (some just don't give a T$%^ )

We have more than our fair share of them, in the UK too ...lol!!

Thanks for the responses guys. Surely it would still be easier to just fit an insulated DB? Why fit a metal clad one only to then have to consider additional insulating measures? Hmm. Still thinking about this one!

It depends if you need to be making off glands or tube work onto it , it can become a bit of a pain finding a plastic board which will allow this .
I know there is always the option of putting a piece of trunking in place and come into that first , but sometimes space or aesthetics may be a limiting factor .

Are there any rcbos on the market that break both neutral and live?

Most of the single pole break live and neutral

Just checked, the Schneider C60H does not break the neutral, checked with a c6,c20 & c32

They are single module rcbos

There are single module double pole but mainly cheap and nasty

I think the IET permit the tails for a TT to be fitted to a metal clad, there is guidance
Something like they must be secured and the entry must be enhanced.use of a plastic or rubber gland or something else

Just make sure the tails go through the same entry hole, or make a slot between them - Eddy Currents!

There's not really much to think about - it all depends on what fell off the back of the lorry.
