extractor fan on lighting circuit?

[ubertossa]

hello all .. is it ok to wire a 4\\\" extractor fan into the lighting circuit via a fcu take from the lighting circuit? .. it is a timed fan so i need to take a wire to the switched side of rose anyway ,and also what size wire should i use 1.5mm or 2.5 ? soz if this is a noob question but i am a noob

For the timer function to work, you need a live, switched live, neutral and earth - 3 core and earth cable is required, in 1.5mm². This will usually be run from the ceiling rose in the room you are having the fan. an FCU isn't required, but a 3 pole isolator (with fan written on it) is.

I didn't think a WC came under the special locations imposed on a bathroom (a room containing a bathtub or shower basin), hence I can't see any reason why you can't install the isolation switch inside the room, just not too close to the handwash basin (splashing risk).

oh i see ..

There are no restrictions specifically around a wash hand basin, unless that basin is within a restricted zone to start with. However, some lighting association in this country has devised a system of zones based on the zones in the regs to cover areas around wash hand basins where lighting is installed close by.
