18th Regulation 411.3.4

[NMJones]

Afternoon all,


Have a quotation regarding garage lighting which requires alteration. It’s a set of flats with a seperate large garage area which id class as commercial hence not needing an rcd as reg Regulation 411.3.4 states only in domestic.
The head of the flats is saying it’s classed as domestic area.
Board is mcbs but unsure I’ll squeeze a RCBO. C


Can you also just cover your own alterations with RCD or does it now have to be at the origin? I’d read on this forum it’s changed


Thanks in advance

Technically yes. I have received verbal advice from NAPIT that I can continue to use RCD spurs and sockets, but they wouldn't commit that in writing as, and I quote "that's just my (meaning the advisers) interpretation of the regulations".

I have used a few RCD spurs (which are manufactured to BS 7288 I believe) for providing additional protection since the introduction of the 18th but these have been listed as departures on the relevant certs.

I can see that this is a sensible and compliant use of a departure. It can be proved it offers the same level of protection.

Would like to know the reasons for the change in these regs though.

There is also this thread in which it's discussed.

I think we'd all like some clarity on it.
