Opinions please.

I have an extension to wire this week which is a garage conversion comprising a study, shower room and small store area. The supply is TT and I'm intending on running a 16mm sub main from the existing mains position under the suspended floor through the hall in the house and installing a new small CU with RCBOs in the new store area. Due to the earthing arrangements I'll fit an S type 100ma RCD and 60a Switch-fuse [possibly 63a MCB] at the supply end, either seperate units linked by tails or integrated in one unit if I can source something suitable. Do you think these items should be Amendment 3 compliant as I don't think I've seen such a beast yet ? Any pointers to similar recently used kit would be welcome. :smilewinkgrin:

Where did you get the 'containing opds' bit from? It doesn't say that in the regs.

A standalone RCD in a 2way enclosure is very similar switchgear to a CU.

Why would the DNO give a monkeys? After their terminals they really don't worry too much unless your tails are too long or you damage their network somehow

The RCD will be going in the same Amd 3 Compliant enclosure as the cartridge fuse, the RCD will take the place of the usual DP switch [100a rated 100ma time delayed] so I'm covered and it'll be a nice tidy solution.
