Hi all
I've got a training assignment to do which is to design a circuit for a job I will be doing with my boss. He wants to see what I come up with having viewed the job and spoken to the client.
Basically the job is supplying lighting and sockets to a new extension comprising of three double socket outlet, two wall mounted up lighters controlled by one side of a two gang switch and one downlight controlled by the other side.
As far as I can see there is no easy way to extend any current lighting or ring final circuits without making a lot of holes and a lot of work which the client doesn't want, but there are two spare ways on the consumer unit which is right next to the new extension. So my suggestion would simply be run two new circuits from the consumer unit.
Only problem is that the client thinks he knows a bit about electrics "maybe he does?" and has started going on about only using one way from the consumer unit, he wants a radial supplying the sockets and a fused spur feeding the 3 lights.
seeing as the max current demand for the lights is about 1.3amps and I can't find anything in the regs which says I couldn't run the lights of a 5amp connection unit spurred off the socket circuit or spurred off an exsisting lighting circuit at the consumer unit. Am I missing something in the regs? And should I design my circuit as the client wants, or is there any reason I should suggest that the two circuits be run from their own circuit breakers at the consumer unit, eg, future proofing if he wants to extend the circuits, or a deveation from the regs if I've missed one
I noticed that the RCD takes up 3 ways in the CU, so I could suggest putting in a newer smaller RCD that would leave room for another way off the CU for future extensions.
Just wanted to hear your thoughts before I hand my design over to my boss.
