Hi Guys. Great site.
I need power in the garden shed. The load will only be lighting and a couple of sockets for hedge trimmer, saw etc. Length of run is 45 metres. The plan is to use 2.5mm SWA buried in a trench. Questions.
1. Consumer unit is at the far side of the house, awkward to reach, so I'd like to take it off the downstairs ring main from the back of a socket on the garden side. Is this OK?
2. How deep should the trench be? (We're having a digger to level the garden, so this can be done at the same time)
3. I guess we'll need it RCD protected. Should this go at the house end or in the shed, with an FCU in the house? Or what?
4. Will the shed need its own MCB unit or can the wiring just be hard-wired into the supply?
5. Should I drop an earthing rod at the shed end, or use the household earth?
6. Should I earth the SWA shield?
7. What's the best way of bringing the SWA through the house brickwork? You can't just shove it through a hole as SWA doesn't bend enough. Can't see a junction box for that purpose in Screwfix.
I'm heavily into electronics and a keen DIYer but not up to speed with modern wiring practice. Looked here for an answer, can't find this exact situation as I don't keep koi carp! Can anyone advise?
Thanks
Pete
