Hi, hoping someone can give me a little guidance on this.
At present I have a CU under the stairs with a two radial circuits off a single 16amp MCB both go to double sockets. I want to fit two external lights and was planning to do this by extending the radial circuit from one by adding two switched spurs and then running 1.5 T&E to the external lights. The runs will be about 5m and 10m.
From reading this forum this seems OK and also OK to do DIY (No part P) as it's an existing circuit, not in Kitchen or Bathroom and there's no external runs of cable as they'll be going directly into the light.
The one thing that's put doubt in my mind is a piece I read that said:
"There is no limit to the number of sockets used on a radial circuit providing the circuit is contained within an area not exceeding 50 square m, and, just like a ring main, spurs, or extra sockets, can be added. The number of spurs must not exceed the number of existing sockets."
I've tried searching this forum and can't find an answer and it doesn't seem logical to me. I'm thinking it meant don't spur off spurs or in this case are there effectively three "sockets" and two spurs.
Any help would be much appreciated.
