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:
ground floor sockets ring
first floor sockets ring
attic sockets ring
freezer / alarm circuit
ground floor lights
first floor lights
bathroom heat matt circuit (3 locations)
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.
You need to find a suitable electrician before you start and agree on
the standards they expect from you. Otherwise, you risk getting to the
end and finding no one will connect up and sign off your work.
Yes, although environment factors and length of cable can change these
requirements. Domestic lighting circuits can usually be done in 1mm.
You don't need any capping (although I do usually use it, or oval
trunking) and it is not normally 50mm deep as that would seriously
weaken many walls, but you will need RCD protection on all circuits
buried in walls.
You should buy a wiring book based on the current wiring regs, and
also the IET On-site guide (again, make sure it's to current regs).
Latest changes require the use of a metal cased consumer unit which
can contain a fire breaking out inside it.
