good morning
i am about to undertake rewiring my 1930's edwardian semi as i am on a very limited budget. i intend to contract an appropriately qualified electrician to make cu connections, testing and sign off.
it is some years since i did my last rewire and so i am looking for some guidance on cable specification, methods of chasing / protecting cables in walls, fixing through stud walls / floor joists etc.
i intend to have several circuits:
kitchen ring cooker ground floor sockets ring first floor sockets ring attic sockets ring freezer / alarm circuit ground floor lights first floor lights attic lights bathroom heat matt circuit (3 locations) electric shower outdoor garage / workshop ring
am i right in thinking normal sockets is 2.5mm twin and earth? lighting is 1.5mm twin and earth?
and what capping do i need to cover cables chased in the wall - i think it's metal and does it have to be 50mm deep?
any help will be gratefully received.
many thanks.
