Power to a shed

[bhamoggy]

Instead of a direct run straight to the C/U can I go into a socket on a ring main inside the house, run cable from that outside and into the shed into a double socket then to a 3A spur for a light? I'd like to run in conduit with 4mm singles. So from inside house on 32a ring to a 13A double socket and onto a 3A fused spur

Would be ok. As long as volt drop etc has been worked out. Why not use swa though? I personally wouldn't use singles and conduit

What size cable u looking to use?

Thanks guys, shed only 5mtrs from house and socket so I'll use 4mm swa then that'll take care of volt drop. Just out of interest, why would you not want to use conduit?

Immediate answer to the conduit is that if there is any mechanical damage to the swa then it will trip rcd. Whereas it won't with the conduit. But I'm sure I could think of other reasons lol.

Remember it needs to be on an rcd

Why??? The installation within the shed or the sub main feeding the shed.

If it's all spurred off a ring and that ring is protected by an rcd at the board, that's enough, don't need to add another one in the shed for discrimination surely ?

Correct.

Was just saying about the rcd, in case the ring wasn't already on one... Should never presume these things. 
