Bathroom Fan Fused at 3Amps

[ianphilip007]

Hello Guys

Just a quick question re Bathroom Fans and that some manufacturers state that they are to be supplied from a 3 Amp FCU

i have two Quries really that i just need clarification on if anybody can help.

1/ when the bathroom lighting is on a loop circuit ( and is supplying another room from the rose) Does the loop out from the bathroom rose have to be fitted to the supply side of the fcu and then onto the next light

2/or is it acceptable to leave it in the rose loop in even though the lights that it will supply will now be fused at 3A instead of 6A

Found on QVS direct.com, says 3 pole. Never used them so can't be sure.

I assume the fuse just protects the perm live in that? My biggest concern with that and the people who connect an FCU in a similar manner is that if the fuse blows the sw live can still remain live.
This could easily lead to diyers catching a shock because they think its all dead when its not.

I've seen a few of these isolators, but the only way I can see of complying with regs AND manufacturers instructions is to 3 amp protect the lighting circuit which the fan will be supplied from.

Exactly, we could then put a nice little row of switches and FCU's above the bathroom door, because that will look so nice!

And why is it the norm to put isolators above the door? isolators for everything else in the bathroom go at socket level so why shouldn't this?

Do people still fit the isolator above the door when they fit an inline fan in the loft? Personally I put the isolator in the loft with the fan itself.
