Extract fans, spur?

[Cj24]

Hi, do extract fans need to now be on a fused spur aswell as a fan isolator, Iv always just wired straight from lights to isolator but am now being told you wire to a spur with 3 amp fuse then isolator then obv fan

If the manufacturer's instructions say it should be fused at 3A then you're meant to do it -- 510.2​ (page 89 BRB)

If it's a timer over-run type this usually means fusing the light that the fan is running off as you'll have perm. live and sw. live running to the fan.

I've just fitted a 'standard' fan in a kitchen - didn't mention a fuse in the instructions - so straight off the lighting circuit.
It didn't require an isolator, either, by the way....just straight off a switch.

The manufacturers instructions are the key, if they say fit a 3A fuse and you don't, you know EXACTLY where the sticky stuff will land if something goes wrong!

Yer. Not all of them do. I've come across the odd 1 where manufacturer's instructions say they should be fused at 3A.

I really can't see the point when it's on a light circuit. :yawn:

I'm not talkin about a kitchen fan I'm talkin About in toilets and bathrooms, so a fused spur is only required if instructions state 3 amp fuse

Toilets and bathrooms require a timed fan now for regs. You can still fuse it if you want by running the feed through the fcu before the switch.

Which Regs?

Don't think a fan is needed if there's a window that can be opened?

As far as i know its a building regs thing wayne But was told this from someone who renovates and buys/sells properties so maybe i should have checked it out first for myself before posting........but if its wrong its wrong....

Yeh, I wasn't saying you were wrong - it was a genuine question.

I've had cause to read up on it recently and I couldn't find anything specific in the 'Electricians guide to the building regs', so I just wondered if you new more.
