Regs on fan isolators

[Spark123]

Can you expect a little old lady to get up the ladders and start disconnecting a fan?

If something goes wrong with a ceiling luminaire in which there is a permanent live, can you expect a little old lady to get up the ladders and start disconnecting it?

Why is an isolator needed? Logical explanations and applicable regulations welcome.

If you are going to do the job, do it right and fit the isolator above the door or at the side near the ceiling. That way it is easy to isolate when your fan goes wrong.

Can you expect a little old lady to get up the ladders and operate the switch?

The chances of a failure in a light fitting causing it to stay on are a lot less than the chance of it happening in a semiconductor device such as a fan timer.
At least the little old lady can use a brush shank to press an isolator.
Have come across plenty of fans where the timers have given up the ghost making them stay on, cant think of it happening in any light fittings unless someone has been tinkering.

No offence, but I hear the sound of straws being grasped.

I don't - it is a logical reason to be able to turn the fan off independantly of the light.
I had one not so long back when there was a fan in a loftspace which stuck on, the occupier was a bloke in a wheelchair and his elderly father. The father wasn't going to get up into the loft to disconnect the wiring to the fan.
If there was an isolator the bloke could have switched it off and wouldn't have warranted an immediate callout.

Fair enough.

regs who knows.

Often because of manufacturers instructions. You know the reg number.

Afaik, A lot of fan instructions now show isolation for lives and neutral, so with a supply from a one way pull switch , technically you are not conforming to the manufacturers instructions, would that violate the regs.

Yet you continue to repeat the question. Why?

I am mildly irritated. Why?

Because you can isolate the fan for maintenance by switching off the lighting circuit.

OK - that doesn't get the neutral, but the same is true of almost everything else....

I continued.

Now I've stopped, because I got an answer. I hadn't realised that failures were commonplace - I was thinking that isolation for maintenance was a fairly academic issue. Sorry if you found that irritating.
