wiring in 12v bathroom fan

[hornblower67]

Have an existing 12v fan in bathroom....do i just wire in conventionally from lighting circuit but via a 12v transformer?

How is it wired at the moment?

Does it have a timed overrun?

Surely its a stupidly simple job, if you are just replacing an existing fan like for like????

not wired in at the moment...
not sure about timed overun.....
was presuming I would take feed from ceiling rose and reduce to 12v?

Why have you got a fan installed but not connected up?

Do you know if it works?

not sure about timed overun.....

Well you need to be, because that affects how it's wired up, what sort of cable you need etc.

was presuming I would take feed from ceiling rose

Do you want it to come on with the lights?

and reduce to 12v?

That's an odd thing to be "presuming" - you do have the transformer the fan needs, don't you?

I am still confused about

Have an existing 12v fan in bathroom....

If you have one in the bathroom already then wire the new one like the old one.

If you have not already got one then read and follow the links in BAS's post together with the MIs that come with the fan.

no...its a local authority refurb where they put a 12v fan in the wall and leave you to sort out from there....nice of them i know!

Surely they also provide the transformer?

Have you bought the place, or are you a council tenant?
