Bathroom fan isolation

[smiffy911]

Without digging out my O.S.G am I right in thinking no triple pole isolation switch is required if there is a window in the bathroom thus lighting circuit can be isolated for fan maintainance.

How is a three amp fuse going to stop a fan 'overheating'?

 

[lurch]

it wont stop it from overheating, but it has a characteristic of going pop if fan is drawing too much design current! its called overload protection

I think you are referring to if the fan stalls then there is a chance of overheating no through normal operation, this subject has been discussed to death before but vent axia range are now internally fused so no need for fused spur just triple pole isolator

i fitted a fan a couple of weeks ago that asked for 6a. It was a retrospective fot so the extra cost outweighed the hassle of fitting spur. . .

You can know buy a 3 pole isloator with intrgral fuse holder(comes as grid type setup)about £6 seen them at the local wholesalers.

OOOOH my favourite topic!

But I can't be bothered. Too bored of this debate now

The 6a MCB would probably trip before the 3a fuse blew anyway.

I thought mcb's have to run on overload for a while before tripping too?

You got this picture yet ????

So a fused triple pole isolator, which is fused live, switched live or both.? I asked at edmundsons and they did some digging and couldn't find one, let me know if you find one .
