3 amp fusing for extractor fans

[chloebear]

:banghead: Hi All,
Just had my NicEic audit and have been picked up on not fusing extractor fans down to 3amp. Normally the installation of extractor fans would come off a lighting circuit via a 3 pole isolator to the fan, unless the fan has been installed utilising a cct other than lighting I would not use a fused spur for the fan. If all 4" fans have to be fused 3amp this will mean installing a fused spur and a fan isolator for each fan?
Also most fans have 2x lives - Permenant & Switched - so which one should be fused, or do we now have to fuse both??

Coments and ideas would be appriciated.

but a fart fan ain't on a dedicated circuit.

If it's on a an fcu, is it then on it's own circuit?. I'm missing something, aren't I?

Yet, how many times have you found 15a fuse wire in a 5a holder to solve a problem. I did last week. So fuse wire and a 3 amp fuse can be changed buy the customer in a fault. Changing a CB from 6a to 16a is a lot more difficult

Found some 2.5 cpc once...lol....

Would that be dangerous though? as It may appear dead if one fuse had gone, yet it would still be live.

Edit: and no i'v never seen one

Come on....ever heard of steinels mate....always prove and test for dead before starting owt mate.....

nope. a circuit starts at the CU. if you fit a FCU to a circuit, then whatever is fed by that FCU is part of the original circuit. it is not a new circuit.
