Extractor Hood. Same circuit as Cooker.

[mcquiff]

I will have the cooker on 45amp circuit, with 6mm2 twin earth cable. The oven will be on another circuit.

I'm just trying to reduce the amount of cabling that I have to use in the walls.

Can I run the extractor hood from the cooker supply.
It will still have a fused switch to turn it off.

I know it can be done but would it be inline with the rules?

Many thanks

Matt

Strictly speaking no as cooker should be on dedicated radial circuit.

In practice providing you can connect from the cooker switch with as short a length as possible of cable to the FCU, and the switch will accommodate a 6mm+2.5mm cable, it's okay.

Dedicated does not mean independant.

Or from the cooker outlet plate.

I agree with the principal and consider it a good thing to have the hood on the cooker circuit so that all the cooking appliances can be switched off in an emergency.

It prevents a chip pan fire being drawn through the hood.

1mm² would be sufficient for the hood.
I do not consider this a 'power circuit' where 1.5mm² is the minimum allowed.

In rented properties an unswitched FCU for the hood, wired to the load side of the cooker switch, forces the tenants to use the hood when cooking.

oops, of course I meant the principal principle, probably.

Thanks for the help, I'm going to keep it on the radial circuit. and oven on its own, saves arguments.

Yes, no argument.

Cable installation method?
CCC?
