Cooker hood wired off consumer unit

[diydoh]

Hi there new to the forum and im begging for help already lol,

Just finished installing a kitchen. The cooker hood is a recirculating type and the other side of the wall its mounted on is our electrics cupboard where the consumer unit is. I have taken the flex through the wall and what i want to do is take the feed from the consumer unit as its the closest source.

What size rcd should i use?
Is 1.5mm twin and earth suitable?
Do i still need to use a FCU if its supplied by its own RCD?
Can i use a junction box for the connection of the 1.5mm TE to the flex or should i use a flex outlet plate?

Thanks in advance
James

I presume you mean MCB (miniature circuit breaker) so 6 amp.

Is 1.5mm twin and earth suitable?

Yes, 1mm² would be alright.

Do i still need to use a FCU if its supplied by its own RCD?

You do not. However, if the manufacturer's instructions so state then you will have to.

Can i use a junction box for the connection of the 1.5mm TE to the flex or should i use a flex outlet plate?

You could but dependent on previous answer.
This is notifiable work - but more important is that the work should be tested properly. It may work now but not as it should if something were to go wrong.

This is a small job but I deduce that you have done other work. It should be tested. Do you have the necessary equipment?

I have done other work on the electrics but mainly moving items. For example relocating cooker point and sockets. I will get it tested to be sure everything is ok. Many thanks for the above answers.

As it is a recirculating hood, not an extractor, it will serve only as an ornament. So no need to wire it in or switch it on.

If one day you run some ducting to the outside, so that it starts to serve some purpose, you can connect it to the kitchen lighting circuit.
