Have yet to come across oneOut of curiosity, does anyone know if this 3A fuse requierment is also seen on fans sold in the EU where small fuses are pretty much unheard of for mains supply use?
Would it be a comepletely insane idea to request fan manufacturers to market a fan not requiring a 3 amp fuse?. Which to my knowledge works pretty well in most countries.Out of curiosity, does anyone know if this 3A fuse requierment is also seen on fans sold in the EU where small fuses are pretty much unheard of for mains supply use?

Secondly would it be sensible to treat a fan with a permanent live in the same manner as we treat a ceiling rose with a permanent live? Or should we start installing 3 pole isolators for them too?
Came here to post the same, looks like it needs a two gang backbox though together the switch, isolator and fuse.Light switch, Fan isolator, Fuse.
Did I misunderstand you? The triple pole isolator is not directly related to the motor.It could happen if manufacturers start fitting motors to ceiling roses.
Which is precisely the situation you would have replacing a ceiling rose in the bedroom next door to the bathroom. Need a head torch?Which presumably means any future works on the fan are done in the dark.....
Unusual for a bedroom not to have a window though.Which is precisely the situation you would have replacing a ceiling rose in the bedroom next door to the bathroom. Need a head torch?

Correct. But my point related not to the purpose of the permanent live (be it ceiling rose or fan) but to the fact that an electrician deals effortlessly with the replacement of a ceiling rose without the need for a local isolator so why can we not do similarly with a fan?I couldn't see how fans could be compared to ceiling roses. The former has its permanent live connected for overrun of a motor, whereas permanent live at a ceiling rose is simply a junction.

I’d argue it’s equally for the convenience of the occupier. A fan motor is more likely to fail at some point than a ceiling rose with no moving parts and without a DP or TP isolator that failed component may well result in a home being plunged into darkness until the fan can be replaced.Correct.

OK. But your point is.......But an extractor is a more complicated mechanical assembly with various moving parts. Also may need cleaning out periodically.
It's an argument. Not sure I, m won over by it. I, m all for local isolation of course. But I, m all for consistancy in its application too.I’d argue it’s equally for the convenience of the occupier.
Consistency? Have you read BS7671?It's an argument. Not sure I, m won over by it. I, m all for local isolation of course. But I, m all for consistancy in its application too.
That’s what I do.....This thread is comedy gold, sorry. Strikes me that if it's really such a big deal, then given that in a new build it's all LED lighting anyway, just stick a 3A CPD at the start of the whole lighting circuit, job done.

They are all reasonable points. But the triple pole isolator was introduced originally, not for the reasons you mention above (though valid) but because of the perceived dangers of the permanent live at the fan itself, should someone attempt to change or service the fan. Of course the exact same dangers are present at a ceiling rose. An amateur would be at risk in both scenario, s.You said we manage without an isolator for a rose, but not a fan. And I'm saying that a motorised appliance needs an isolator for maintenance.
Or in case of a fault of course, as mentioned by others.
