Cooker hood wiring

[600rob]

I want to install a cooker hood to replace my old one thats stopped working.

Im after one that you can just stick a 3 pin plug on and run off a mains socket.

was looking at this but apparently it should not be used with a socket.

question:
why cant they all lust be wired up to a plug and what governs whether the hood should be wired directly or if it has to use a socket?

Why do you think that?

There's no reason why you can't put a plug on it - or anything < 13A within reason.

I should have mentioned there's a question in the product Q and A to which screwfix answered it should not be wired to a plug

"This product states that "the appliance must be connected directly to the mains using an omnipolar circuit breaker with a minimum opening of 3mm between the contacts." so you should not use a plug on it.

Thank you for using Q&A (CW)"

I couldn't work out why this might be since some units say its fine and others dont.

Thought id check withe the knowledgeable folk on here

Ignore them.

Whoever wrote that ought not to have been given the job of answering questions.

I also have noticed that they don't seem very good at their job.

Manufacturers instructions are guidance only and don't have to be followed especially if they are wrong. Cooke and Lewis have got it wrong before.

The instructions really just mean that you need some kind of double pole isolator, which would be the main switch in most installations. Somehow that's turned into omnipolar circuit breaker which is clearly a bad translation, and that has been further translated into plugs are not allowed.
The regs regarding isolation say that a plug and socket are a perfectly acceptable mechanism for isolation, if that's necessary.

Thanks everyone for you input and clarification

So i just picked up the hood in question and the leaf only has a live and a neutral. No earth.

Its this still okay for use with a 3 pin standard plug?

Does it have a square inside a square icon on the ratings label?

What does that symbol indicate?

 

[EFLImpudence]

It means it is double insulated (or has reinforced insulation) and does not require earthing.

This is considered 'safer' than earthing.

 

[DetlefSchmitz]

It is claimed to be double insulated and so suitable for not having an earth. Just connect the two wire that are present into the plug.
