Prosecution

[decolad69]

there is one, better still if the fan manufactures could build a inline fuse holder or thermal cut out to stop all this booox
i heard of a cu with a 3amp mcb dedicated to supplying extractors?

Totally agree with you, how do you fuse a fan at 3a which has a L/SWL from the bathroom light ? The last one I installed I wired the supply to the bathroom light via a FCU to protect both fan L and SWL.

btw what type of fan are we discussing? one of those cheap £12- ones or something like a greendale
also if you energize a bathroom fan then jam the impellar does it get overheated and catch fire?

Hmmmm, so the ECA are making a bit of a push regarding 134.1.1 ? This presumably includes torquing of terminals in distribution boards ?

In other totally unrelated news, I see the ECA have started selling torque screwdriver sets.

Why isn't there a triple pole fan isolator with a fuse in it on the market?

Or if there is I've never seen one.

I believe that there is.

I thought there might be but I've never know of one, but saying that I've never looked.

If this is something so important then all triple pole fan isolators should have this.

How would that work though?....there's two lives.

True 2 fuses lol

On that note even a fused spur would be useless unless you fuse down the lighting for the room before you do the switching.

We could also try and instal a rcd socket, and chuck a 3A fuse in a plug and flex to the fan. Should more or less comply. Lol

In all i have never done a 3A fuse down on a bathroom fan, but what was the prosecutions findings and what was the fine ?? I know he didnt mention the company, but normally you get a tidbit of how much etc.

 

[telectrix]

i think most fans' instructions call for just the perm. L to be fused, not the s/l.

Sorry?

Now you mention it my NICEIC assessor was banging on about fusing fans at my last assessment. When he asked me what I did, I just said I followed BS7671 and manufacturers instructions. He accepted that and then mentioned the fused switches, others have also highlighted.

Sorry?

If you've got a 3 core t+e a fused spur isn't going to help is it. As you can't fuse down live and switch live

If you fused the feed into the room down then it would be.

Not that I'm saying that's a good idea.

Time to invest in 3amp MCBs i think, although if everyone did that I guess they would change the game and insist on 1amp fuses to make sure they've got another get out of claim card

I always fuse down to 3a where specified in the instructions. Many actually call for local DP isolation. Easiest way to do this IS to fuse down the whole of the bathroom lights, thus encompassing the switched and perm lives. Nobody can argue then. It's a ballache if the fuse blows of course, cos it takes out the lights as well......but hey ho. The fusing down is a bit of a mystery to me, cos the circuit is protected at 6a anyway! And would a 3a fuse blow before a 6a MCB operated?

 

[electric will]

A total load of rubbish! If you stall one of them tiny fan motors, there's no way it could cause enough over current to start a fire Come on get real!

 

[morph]

just use a 3 A cb

 

[markc123]

Just had a quick scout on the good old google, apparantly MK make a 3A MCB? really? i never knew 3Amp MCB's even existed, where the F have i been living all this time!

If it is true about fans needing 3A, then if its a new build you could take it from its own circuit...i fear for this though, wont be long before literally everything will have its own dedicated circuit.

 

[Rampantchilli]

just looked on the IET forums, and low and behold, its mentioned on there, via an NIC inspection, but from 12 months ago, and story says its from recent years, seems like a bit of NIC fore play before they s***w you

u only had to ask lol

 

[markc123]

I honestly never ever new that 3A MCB's existed hahaha oh my days.

Isit just MK that make them?
