Evening fellas,
I'm doing an outside light for my neighbour as a minor for my NICEIC assessment.
The house is on a fairly ancient consumer unit with what look like square-d breakers. Haven't had the cover off yet, just a brief glance so not sure if bonding is present let alone effective. Obviously not an RCD in sight.
Only 4 circuits, sockets, lights, immersion, kitchen socket. The last chap had even left info+diagrams in the CU!
If I stick a switched fused spur on the sockets upstairs will it need to have an rcd to protect any subsequent wiring for the light? I'm planning on chopping in next to an existing socket (still mounted in skirting board) and going straight out the backbox with some carbon black 1.5mm flex, out the wall and straight into the light with probably 50mm flex exposed before it terminates.
My understanding is that as it's not a socket outlet it won't need an RCD to comply. The additional wiring (just to extend the ring through the spur) won't be at a depth greater than 50mm but I've just read some blurb from Elecsa which seemed to suggest that the cable up to the spur would not need to be RCD protected, and if that doesn't need and RCD then I can't see how the cable for the PIR security light would need one.
I realise we're only talking about the cost of an RCD FCU as opposed to a regular FCU but I would like to have it clear in my own mind.
Sorry for the essay,
Any thoughts chaps?
many thanks
Ben
