I've got a Workshop that already has power to it installed by the previous owner (a builder). It's fed by a separate 63Amp fuse in its own distribution box off the main supply board in the House. The cable goes outside into the garage into another small distribution box where there's another 63amp fuse. This box has 2 fused circuits, a lighting circuit and a power circuit. Both are in a radial configuration. There's also a spare slot for another fused circuit. Main Fuse Box in House Workshop Fuse box The Power circuit already has a couple of plastic sockets installed that I'm going to replace with metal ones. Most of the wiring is in the roof area of the Workshop with runs vertically down to the sockets and either bare or covered in plastic trunking. I'm going to be using a few Power tools, (Table Saw, Thicknesser / Planer, Mitre Saw) but only ever one of these plus dust extraction at the same time! QUESTIONS 1) Based on the above, is there anything I need to change to make comply with regs or good practice? 2) The unprotected heavy duty cable to the Workshop exits the house through an airbrick and disappears underground to reappear out of the gravel into the Workshop. I'm guessing this should be an armoured cable buried to a given depth with warning tape? Happy sorting this out with proper cable but what's the recommended method of joining the cables where it exits the house / enters the workshop? A weather proof connection box of some sort? 3) What's the proper method of organising the power circuit/s in the Workshop? Just extend the existing radial? Add a second radial in the spare fuse slot? I think the ideal configuration is a ring circuit (?), if so, can this be done with the existing supply? Not wanting to be obsessive about this BUT I need to be sure it's done properly as no one wants a tickle from Mr Sparky! Thanks.
