Bathroom Extractor Fan

[shapnacker]

I had to change the light fitting in my bathroom as it needed moving to a better spot.

In the loft I replaced the junction box as it was a real mess. Unfortunately when doing so I disconnected the extractor fan.

I am unsure of the make/ model but there are three wores and an earth. They are colour coded thus:

Black
Grey
Brown
Earth

I connected the black to the switch, brown to the live and grey to the neutral but no joy. Is the extractor fan dead or did I confuse my wiring?

Unfortunately when doing so I disconnected the extractor fan.

That was not unfortunate.

Unfortunate was not thinking to make a note of which wires went where before disconnecting them.

Is the extractor fan dead or did I confuse my wiring?

Did it work before you fiddled with the wiring?

If so it would be a remarkable coincidence that it failed between you disconnecting and reconnecting it.

Why not look at which cores go where in the fan?

And test there with your multimeter for voltages.

Thanks for the reply ban-all-sheds. Yes, the wiring was in such a mess that it was really difficult to work out what went where, but I should have taken a picture. Unfortunately I do not possess a multimeter!

Sorry ban-all-sheds. In answer to your question. It did work before hand so I'm wondering if I've blown it!

 

[shapnacker]

My mistake.

Black - neutral
Grey - switching live
Brown - live

Always helps to open ones eyes!

FYI - the use of black for neutral is deprecated.

Working now. Thanks for your help!

Was it wired wrong in the first place do you think?

Well, it worked before you messed with the wiring, so it was not then wired incorrectly.........

It's always good to have a scapegoat though. That's why the Tories keep Clegg in tow

It was in response to this statement Taylortwocities:

"FYI - the use of black for neutral is deprecated."

 

[Taylortwocities]

Ah
Apologies for the sarcasm, then.

Black can be neutral, but it should be sleeved blue to confirm its function as neutral.

 

[ban-all-sheds]

It can, but my understanding is that it's preferable to not use it, sleeved or not, as a neutral, to try and break the black:neutral association.

Thanks for all of your help chaps!
