Bathroom fan and isolator switch

[jimjamyaha]

Hi,

Apologies for the repeat post but I have re-measured the bathroom/fan and it now appears to be within zone 2. I've attached a picture (2 mashed together) with measurements. The fan is mains @ 230v.

We've had an extractor fan wired into our bathroom by an electrician. However he's put the 3-pole isolator next to the fan.

The fan is a timed/humidistat one that is triggered on by the light and then runs on it's own.

He's certified the work with a certificate - should I get him back to sort it out, or is it ok to be left?

Thanks,

James.

Really needs to be moved out of zone 2 and as he will be moving it safest if it is outside the bathroom completely.

Shouldn't really have any kind of switch in the bathroom at all.

If your bathroom has a window, you can get the electrician to remove the isolator completely, as the function of the isolator was to isolate the fan whilst the lights remained on, but only if no natural light was available. I think its in the building regs page 64???

Best regards and hope this helps,

Sav i have heard this before and didnt believe my ears but as u have said it i will investigate..

What you are saying is if you have natural light you dont need an isolator as you can isolate lighting circuit and use the light from the window,,

I think its a crock of **** ( my opinion) so what happens if you are called to that same property at 5pm on a winters evening it will be pitch black therefore no light,

So your way only works if you work in daylight hours,

this is a rant at what your saying and not you,, as ive heard other people say this

Eddie,
I am with you on this and as good practise, I also fit an isolator where possible.
I just checked the regs and its on page 65 and quote "An extractor fan supplied from a lighting circuit for a bathroom without a window should have its own means of isolation, as otherwise replacement or maintenance of the fan would have to be carried out in the dark"

Probably written by someone in springtime !!!

Like I said, I always fit on where possible, but in this scenario, if a window is fitted, then thats the easiest option.

Best regards Eddie mate,

Sav

Glad u didnt take it the wrong way... its just backward..

Have you zoomed in the photo?? The isolator is really badly fitted regardless.

What is the height from the finished floor to the isolator? If it is above 2.25M then it is outside the zones.

 

[chris gray]

well sav you have taught me something today thank you. i always believed that an isolator was required.
jimjamyaha
chances are that if you read the manufacturers fitting instructions you will probably find that it needs to be fitted with a 3amp dp switch.

So what happens when a lighting circuit needs maintaining in the dark??

Do we fit isolators to each pendant?

surely isolators on fans are a good thing as u can change them over or hoover them with out turning off circuit,,

Technically, ANY motor should have a local isolator.

I was just being difficult.

It will isolate itself if you stand in the bath and work on it.

Did you know that you now have to fuse extract fans at 2 or 3 amps ,this was due to a few cases of fires caused by the fans seizing and some poor guy loosing his life ,spark was prosecuted and lost because there was no additional fuse ,you have to fuse both switched and perm lives ,only way ive managed to do it is to drop the feeds into a fused spur then to an isolator then the fan ,i was advised this by the elecsa inspector

That thing is dog rough wouldn't be happy with that in my house.

Have you got a reg number or reference for this?

 

[ezzzekiel]

only if the manu instructions state it needs to be fused down and their instructions precede regs
