Hi,

Can I take the supply (via a 3 amp FCU) for a cooker hood from a domestic lighting circuit?

Regards,

Yes, if it's an ordinary fan and lights of low wattage.

Some people will say you don't need an extra fuse, but the FCU will give you isolation (if switched) so is a handy way to do it; and in the event of a fault might save all the lights going out (but you can't rely on it as the 6A MCB will probably trip at the same time)

It's extraction rate is 500m cubed/hr and has 2 x 40w lights.

Is this still OK?

I was thinking more of the wattage.

So it is not necessary to install a separate FSU for the hood?

Is a viable / allowable solution to put a switched socket (on the ring main) located in the hood out of sight, then fix a normal plug to the hood flex and fuse to 6A?

You ought to start a new topic.

The previous poster wanted to add his cooker hood to the DOMESTIC LIGHTING CIRCUIT which is itself fused to only 6Amps. If you were coming off a ring or radial you would have to fuse it down, normally through an FCU. 3A would be ample if it was the only load.

A switched socket is a strange way to connect a fixed appliance like a cooker hood. And it should not be fitted out of sight where a person would not be able to see and isolate it in an emergency, like the hood sparking or catching fire.
