evening all, my sparky is booked for two weeks time but he's currently on holiday so I can't get him to advise on this. Myself and the builder need to get on with boarding and skimming a stud wall tomorrow but I know we're going to need some wiring for an extractor fan in there. It's a utility room, the only window is a velux in the roof (likely to be opened only rarely I would think). My plans indicate an extractor fan, but it's the detail I'm stuck on;
1. Is it OK to have an extractor with a simple on/off pullcord rather on a timer?
2. If I have an extractor with no timer, is it OK to just have the on/off pullcord and no isolator switch? Fan will be on a 6A lighting circuit
3. I think I read somewhere that you can do this, but you need a pullcord switch with some minimum gap between the switch contacts. Is this correct? (I can't remember where I read this)
Hope someone can help! TIA
Nick
