spur off a ring

[Selfmade]

Sounds like that guy doesn't know much about electricity or wiring! It's max one double socket off a spur from a RFC, (taking account of cable derating factors such as thermal insulation of course). Any more than that and it has to be a fused spur, as then you could draw more than 26A.

HI
you can spur off a ring main as many times as you like provided its fused down... but your limited to 13 amps from the fuse!!

You should have also added, that whilst he can extend as you say, he must also consider the volt drop limitations, which he can calculate, and also ensure that the disconnection times can still be met, and then there is the correction factors for the installation reference method. i suggest he goes back to the painter in question, and tell him that he didn't give him the full info.

Right i am off to change my gas boiler. The window fitter said it was easy, just join the pipes back up, put wet ones to wet ones, dry ones to dry ones and see what happens, apparently if i have got it right it will just work, and if not there will be some sort of bang, but i haven't to be worried about it.
