Fusing Fans to manufacturers spec

[Amp David]

This may sound a silly question but how to you wire it if you're using a fan with an over run timer?

Perm feed through fuse, into isolator then out to fan. Neutral and switched into the out of isolator.

According to the manufacturers instructions i have read you only need to fuse down the permernant feed and not the switch feed , so ideal in my mind ill let you know the cost

Yep, perm live only on the ones I've seen. I've also noticed that the rule about fusing it only applies to the UK! Anyone know why we're blessed with that requirement here and no one else is?

It is a bit strange, as the whole circuit is protected at 6a. That isolator with integrated fuse on the perm live is a simple but great idea, as said saves the hassle of having to use two accessories. Why does the perm live need fusing down but not the switched live?

They're both fused because of the way it's suggested to be fed (via the perm live). If no other countries need to add protection, then why do we? I don't believe other countries lighting is 3A to start with. I wonder if it's a misunderstanding that has been propogated across the chinese manuf plants.

Not enough 3A fuses were being sold, its a conspiracy I tell ya!!!

If they insist on 3A protection why not just provide them with one installed? Or am I thinking too much?

That's the point mate, they don't ask any other country to add a fuse (so it must be OK without that protection?).

so why don't we all bombard manrose and the like with emails asking why?

If you installed a fuse in the fan then only one of the SL or L would be fused, if you installed two fuses one in each Line then one fuse could go and still leave a live circuit on the fan. You want the fuse before the isolator. As per post #1

but the whole point of the post is that the manufacturers instructions only call for the permanent L to be fused.......is that a mistake on their part?
