The master socket installed by former tenant’s not working, so I bought a new master socket and connected the wires exactly as they were connected before. (Blue to A and Orange to B) And it’s still not working.
Is the wiring wrong or is there some other fundamental issue?
( colours of the first wire: blue, orange, brown and green
colours of the second wire: blue, orange, green, white&blue, white&orange and white&green )
Why were you expecting the socket to work? Have you got a service at the address.
