What a DIY disaster
I've just drilled into a electircal cable.I've just had a utility room built which has loads of sockets for mashing machine etc. and are all switched on at worktop level to make it easier.However i did have a socket installed on its own just in case i needed it for something.I did use a detector but forgot about this socket and drilled into the wire.Now i think the wire is still intack but the bare wires ar showing.Now can i just chisel out a little bit of wall and wrap electrical take around the wires and inbed back into the wall (easiest) or can i connect the damaged wires together using a terminal block (what ampage terminal block do i use) and again inbed back into the wall or do i have to chisel the hole wire back out up to the ceiling and put a fresh bit of wire in and connect back into the circuit with a large junction box.
