Hi.
I am trying to figure out how to put power into my shed but really need some advice. The shed is about 15 metres from the house and will only need a lighting circuit to run a flourescent strip light,about 4 mains sockets to run an undercounter freezer and the usual shed power tools - drill, grinder etc etc.
Currently in the house we have a 1980's consumer unit with MCB's but no RCD - this is completely full. The electricity to the house is economy 7, if that makes any difference.
The plan was to extend the existing downstairs ring main via buried cable to the shed and in the shed, put one of those =A330 garage consumer units with a rcd and a 6 and 16 amp mcb. My questions are.....
How do I physically extend the cable outside, do I simply drill a hole through the wall next to the socket and feed the cable into the metal box through the side and connect the armoured cable to the terminals of the socket or do i need some kind adapter that goes from armoured cable to normal "indoors" ring main?
Once the cable is through the wall do I use that black plastic conduit as it would be about a foot off the ground, is that the idea of the round plastic boxes that they cover where the cable comes through the wall?
Additionally, it would seem that the shed end of the circuit would be the only section protected by an RCD, does this matter?
Thanks in advance for any help
