Kitchen Extractor Fan from plug socket

    Hi All,

    At the weekend I attempted a like-for-like swap-out of an old non-functioning kitchen extractor fan for a new Vent-Axia fan. However, the new fan does not work either, meaning that I've either done something wrong or the existing cable is long dead.

    The new fan says it requires a 220-240V 50hz supply, so is there anything stopping me running a cable from a near-by plug socket to the new fan, instead of the existing cable coming out of the ceiling? Does it matter that the existing cable is presumably off a lighting circuit whether as the plug socket wouldn't be?

    Also, the new fan says it's a Class II double insulated product and must not be earthed, so would I just leave the earth cable un-connected to anything?

    All of this is just a stop-gap incidentally, at some point we'll get the kitchen redone and all this will be done properly. So running this fan off a plug would just be a short term thing.

    Any help welcome.

    Running it off a plug is fine. Use a 3A fuse.

    If you had been trying to connect to existing wiring, your may find that it is fed from a fused spur somewhere that is switched off or has a broken or removed fuse.
    Have a look around the kitchen, they are sometimes hidden in cupboards!

    If you not sure, it looks like this:

    Thanks for your swift reply. I'll have a hunt round for a fuse like the above. It's an old house we've been in for a year or so, so I suspect the wiring is really below regs with some oddities, hence why this will be temporary until we can get it done properly.

    What about the earth wire from the plug? Do i just leave it clipped off, and un-connected with some insulation tape over the end?

    Put the earth conductor in a bit of insulated terminal block (aka choc block).
    Don't use that plastic tape stuff, firstly it doesn't really insulate, also it falls off after a while.

    EDIT: if you have a test meter (if not, why not?) then first step is to check if there is any voltage at the end of the existing cable.

    Perfect, thanks for your answer.

    Or just get a length of two core flex and ensure the fuse in the plug is correct.
