Thanks John, :) It seems that the 17th edition regs has not only introduced new requirements, it's made the design of electrical installation a bit of a grey area. I might forget electric and make it all steam powered! The link provided above in this thread to the legal requirements...

The Earthing system is TNS (cable sheath). Extraneous conductive parts. ...are you testing my aged knowledge by any chance? :D There will be galvanised steel racking which I can cross bond back to the C/U in the shed and also have quite a few hand tools, but I'm not going to attach an...

Hi PrenticeBoy, It's about a 10m run. The cable will be T&E in the house then switch to singles in overhead conduit as long as Part P allows it. I'm replacing more or less what's already there, although it's only a 2.5 T&E at the moment spurred from a ring circuit inside the house. Looks...
