New Lighting Circuit

[carl9254]

Hello, is it ok to power a new lighting circuit, eg new conservatory, from a fused spur which is spared from a socket ring circuit back in house??

That is what I did in my conservatory,

(note to self must test that circuit sometime)

So is that legally allowed aslong as its a fused spur??

 

[supasparxs]

yes it is allowed,

if you look in appendix 15 page 362

the diagram shows fused spur with 1.5 cable linking to double sockets, (as you have reduced the cable size you need to add the spur.

If you decide to wire the lights in 2.5 cable you could omit the spur (I wouldn't and I haven't omitted it in my conservatory

cant you run a new feed in from the cu? my boss frowns on this, so we would run in a new circuit or take it from existing lighting feed.

The cu is at other side of house and its a big house. I thought a new lighting circuit had to be fed from an existing lighting one, didnt think you could get supply rom socket ring, but if its fused i guess its ok.

Better to try and pick up off the lighting circuit but you can spur off the ring just drop the fuse size to suit, i done this with my outside light

Just fuse it down to 5amp, feed the spur with 2.5 though, then you can reduce to 1.5 for your lights
