The alternative would be to have a non-RCD MCB in the house supplying this SWA, and then RCBOs in your new CU.

Run it tight next to the guttering?
Not in it![]()

Fit a socket on supply cable ?That external box might usefully be a socket.
It would need rcd protection doing it that way.You could gland off into an external box at low level, strip the swa really long and run up to the Dist Board in flexi conduit, maybe with a seperate extra earth wire to allow bonding the armour, within the partition wall, that would leave the gland accessible and no unnecessary joints
yes it does, i believe the op said there was already an rcd at the sourceIt would need rcd protection doing it that way.
Yes that’s correct.yes it does, i believe the op said there was already an rcd at the source
I had another idea after reading yours, do what you said but install the swa inner inside a galvanised trunking inside the wall? No rcd protection needed then.yes it does, i believe the op said there was already an rcd at the source

That would mean that shed board doesn't isolate socket.

It would need rcd protection doing it that way.

Which could potentially be useful, and the device at the house will.
