Hi everyone

Just pricing up a long list of remedial works on a recent EICR. Amongst other things, the previous 'electrician' wired up a timer fan to the socket circuit. If one of the above exists then it would save me having to fit a fused connection unit and then an isolator - space is a bit tight.

I have googled but didn't find anything. Perhaps someone has come across one before now? Fingers crossed

many thanks

BB

Do you have space for a dual single box?

You could have a 3 pole fan isolator one side and a grid with 2 fuses in it next to each other.

Hi Baldsparks
Thanks for the suggestion but that's what I'm trying to avoid...
The perm live is the only one that needs to be fused and this then supplies a switch (and switched live) for the timer trigger.

D'oh.... yes why didn't I think of that!!!

Must be having a blonde day...

Thanks Gary

lol. it is Saturday.

Obviously you can only do it if the mains to the bathroom light is wired through the fan switch and not as a standard 3plate light.

Hello all. Tried to reply but I've not posted in so long it appears my original incarnation has been deleted (no one of any importance, don't worry...)! For some reason, aligarjon's post is not showing up for me, but to answer the OP's question, we use Click mini grid. A 3 gang yoke on a one gang plate, a fuse module and a 3 pole isolator which takes up only two ways (no affiliation to Scolmore/ Click, I might add).

Regards

Google 'fan isolator'.

weird. my post has disappeared. I said just fit a spur because if the permanent live is off so is the Switched live anyway. Followed up by my post of depending on how it was wired as to whether it was possible.

What I usually do now is take all the wires out of the bathroom light fitting and put them into a JB, then take a permanent L+N to an FCU then feed the light and fan isolator from there, doesn't take that long and saves all the worry of not complying with manuf. instructions re the 3amp fuse. (which I consider ott anyway!)

Dave.

All this 3 amp fuse to feed a fan which is off a 6B mcb gets my goat.

Maybe we could start using type A mcb's on bathroom circuits, or 3 amp type B's (better makes -make them in their range, trying to get hold of them is a different matter of course)

Where in the Regs does it require a 3 pole isolator?
Thanks
Alan.

I agree Pete, absolute bo*****s! The other alternative would be for some of us to do some research to find the makers that don't stipulate 3a fuses and then list them on here?

Dave.

I don't think it does but manufacturers instructions will almost certainly stipulate the use of an isolator for all poles.

someone posted a couple a while back, one was vortice, i forget the other. They cost about 5 times the price of a basic 4 inch fan though but will get you out of trouble on a strait swap when its difficult to alter the wiring.

we went through a spell of fitting 3amp mcb's until i got a invoice from the wholesalers.


We install dual box above doorways, and as we normally mains into switch we run mains into unswitched spur above door and then a single 1.5mm to switch rated at 3amps for the supply to the switch and wire as normal from there. The other side of the dual box is for the 3pole fan isolator

My mission is to live as long as possible......so far so good!

Or you could have the the permanent L & N fed from the lighting circuit and the switched L fed directly from the back of a ring final socket.

LOL.

Well that`s what I found after a PIR on a residential home and it passed without comment.
Strangely enough the PIR listed (amongst other weird things) two sockets in one room being on different circuits as a defect, even though this was clearly labelled at the consumer unit as to which sockets were on which circuit.

Have been looking everywhere for the answer to your original question. No definitive answer but I saw the link on here and now can't find it.

On another thread someone mentioned Click, again, I couldn't confirm on their product list. Give them a call tomorrow and keep us informed. It will be a useful product.

Simon

I'm pretty certain Greenwood fans don't specify the 3 amp fuse.

We normally go for a switched FCU outside the door feeding the fan and bathroom light. Ok, you can't then work on the fan with the light on but that's hardly the biggest problem in the world.

It also means if you really feel the need to "lock it off" rather than sticking the fuse in your pocket it's possible.......


Stu

Thanks for replies all.

As mentioned, the reason it needs to be fused is because it's supplied off the socket circuit - currently 32A. It's not linked to the lights (has it's own switch) so Gary's suggestion (which has disappeared for some reason) of using FCU on the permanent live is the way to go
