Extractor fan with timer

[Daniel1]

Here is the opposite end, where the light switch is.

As mentioned there is no other switch (isolator switch) and the hatch in the ceiling is gone (he lowered the ceiling and plastered a new ceiling). So not sure there's any real way to access the wiring behind that wall, at all.

As a side note, can the isolator switch go inside a bathroom or does it have to be outside? We'd like to avoid a new switch outside as the paint for that wall has been discontinued and I wouldn't want to risk damage to it, if at all possible/safe.

Thanks again!

What TTC said
They have not run the correct cable because they don't know what they are doing by the looks of things. They have left uninsulated live parts in the fan which is dangerous. You should get someone competent in to fix that and get the original installer to foot the bill.

You don't strictly need a fan isolator, but if you do have one it should be located in the control of the person working on the isolated fan, in the same room, or be able to be locked off.

I assume if we get him to somehow redo this to both make it safe as well as fun the timer, an isolator is then needed?

The fan is on the wall opposite to the wall with the switch in the hallway and I assume the wires are running through the ceiling, is he effectively going to have to cut a new hatch and then repair to get to the wires, or break tiles?

you have a dangerous bodge. it must be rectified. if holes need to be cut, then the cretin that installed that fan must be made to pay for the fix and repair to any damage, no matter what cost. and i'd not trust him to do any electrical work whatsoever. he obviously hasn't got a clue.

yes. i think an isolator is the least of your worries.

I think this thread has run its course. Please feel free to post the job and get an electrician in.

Don't try to fix this yourself, and don't get a mate of a mate in. They really do need some actual knowledge of electrics by the sounds of it.
