Running power to shed

Grumps · 2020-07-06T07:28:27+00:00

HiI know this has been asked many times before, but just wondering...House did have a spur from ring to shed a while back. This was laid under path etc as standard 2.5mm in various conduits (mostly old hosepipe). This was surely the way to do it in the 60's.Anyway, that failed at various places and with some burn marks too. It has now been disconnected by an electrician when he was re-wiring the kitchen. The shed did have it's own set of fuses, but ALL of the electrics have now been removed due to cracking, age, etc.So, is it acceptable to run normal cable in a more suitable conduit as a fused spur off the main house ring along the top of a fence some 20m to the shed? The wire run would exit the house about a foot from the ground, go up the wall about 2m then across about 1m to the fence. Along the fence and enter the shed. Only to be used for lighting and normal power tools.Ta.

I am not aware of any legal minimum specified depth, however 522.8.10 in BS7671:2018 simply says "Buried cables, conduits and ducts, shall be at a sufficient depth to avoid being damaged by any reasonable forceable disturbance of the ground". So under a concrete path can be shallower than say under vegetable plot.

Whatever he does, I'd use armoured cable. I still have mine connected waiting for a new shed, but looking at it its completely unscathed and that would not be the case with anything else out there for that long even if it were in some conduit.
