As the switch is off to the light, that rules that fitting out (Unless it
has be wired to switch the neutral, rather then the live!)

If this is the only thing on the circuit, then there must be a cable
fault, or the MCB is faulty.

Does it trip immediately, or is there a delay?

Have you knocked any nails into the wall recently!?

Any other DIY work done recently?


It trips immediately. Was working fine until this evening and I've not done
any DIY work that would affect it.

I guess that means it is probably a faulty MCB. Think I will leave it until
tomorrow before I try another one
