    Some use the lighting circuit and 3 pole Isolator switch and others may use their own dedicated supply due to having humidity sensors.

    What extractor fan are you trying to fit?

    generally you would wire a fan say, in a bathroom, off the lighting circuit. usually, you feed a permanent live, switched live, and neutral, so as the fan would run on after the light is switched off. for maintenance purposes a 3 pole isolator is often fitted to isolate the fan without having to turn the lights off. manufacturers instructions may also call for the fan to be fused at 3A.

    Domestically you can take them off of a lighting circuit, but need to go to an isolator first. Depending on type of extract fan take a 3core and earth if it needs a permanent feed and a switch wire, from the light fitting to an isolator and then from the isolator to the fan. if the extract has a manual pull cord then only a t&e from the fitting to the isolator and then on to the fan is needed.

    When you have served your time and out on your first PIR, you will be cursing the fool that didn't put a fan on an isolator switch, and you will be wondering for a while why the insulation resistance is low.

    It wasn't taken straight from the shower pull cord without using a 3A fcu about 16 years ago was it? Sorry that was me while I was learning. I learned how loud my boss could shout at me in a bathroom and I've never done it since .

    Or wonder why that fan (with timer) refused to come on after you did an IR, applying 500 Volts across.
