Bathroom extractor fan - bank holiday confusion

[Ljnichol]

:help:
Hi,
Extractor fan stopped working (greenwood axs100svit with timer) so thought I would replace it (Manrose gold with timer). Bit confused with the current wiring though...

Both the bathroom fan (stopped working) and the shower room fan (still working) are wired in as follows:
- neutral - brown
- switch live - grey
- permanent live - black
Plus, earth - yellow/green not wired in or exposed, just cut back to sheath.

But, the isolator switches are both wired as follows:
- neutral - grey
- switched live - brown
- permanent live - black
- earth - yellow/green - Ends in connection block.

Should the wiring not be consistent at fan and at isolator switch re which is neutral and which is SL???

Advice much appreciated, thank you

Yes, it should, of course.

Brown should be used for permanent live and the others oversleeved with the appropriate colour to signify the function.

It doesn't matter but the consensus is to use the grey for neutral.

You will have to check what colours have been used at the light (or this could be a junction box nearby).

Posting your question twice does not make things happen faster.

6pm on a sunny bank holiday? Most sparks are in the garden. We dont get paid for this, you know.
