Extractor fan wiring help

Can't find a reg that says you must do either. But if the MIs say you should then you should.
But as I say, on a standard domestic lighting circuit, electrically, its pointless.

PS, you can get a FUSED 3-POLE ISOLATOR

From memory those ones specify a fuse, as they don't have an internal thermal cut out. Personally I follow manufacturer's installation guide too .

Why what will happen if a 3amp fuse isnt fitted?

the earth will get invaded by an alien race lol

Lets hope that them buggers can understand this electrickety stuff better than what we can....

You got a link to the court case

Sorry no. Could be folklore I suppose.

There is this but it wasn't due to no fuse...

Anyone who ever thought it would is a fool. Proving then Part P take is nothing more than a tax on some electricians.

Those 3 pole isolators are doubtful for compliance as they can only fuse one of the lives, not both........

You fuse through incoming live so covers permanent and switch.
It is up to the installer to make that happen though!

[telectrix]

some fans MI call for a fuse only on the perm L though.

I've seen them installed where these switches are "downstream" of the light switch so they are only fusing on of the lives ..............

We all know that a 3A BS 1362 cartridge fuse is highly unlikely to blow before a BS 60898 MCB trips .

I find it better to supply fans which don't need fuses.
