consumer units

[Peter Woodford]

Could you tell me when installing a fuse board to meet the 17th edition regs does your consumer unit have to be spilt load i.e 2no rcd breakers. Was going to install split board one side with main isolator other with 1No rcd so that not everything trips on one side.Hope you understand this


cheers

Peter,

Basically yes, all circuits SHOULD be RCD protected, so you could install a standard split load board, but the unprotected circuits would need to have an RCBO in place of a standard MCB.

This can work out fairly expensive so a 17th Dual RCD board is the best way to go.

hi
i think u can as long as u get departures from client, but dont think spilt board complies,,, sure someone will tell u if i am wrong

hi
again, knew i was wrong

Is it not possible to have a named circuit before the 2 splits that is not rcd protected ( as long as it does not contravene other regs like buried less than 50 mm )eg a freezer radial, so that it does not suffer nuisance tripping?

Yes you can but as you have said, as long as it does not go against other regs and is clearly labeled it can be left off RCD protection.

cheers - thought i had read that somewhere
