Prosecution

[tigerpaul]

We had our ECA assessor visit today and while we were chatting he mentioned a case in London where a contractor had done an apartment block. There was a fan in a bathroom which had gotten stuck and the motor had caught alight and caused a major fire. Everything he'd done was as per BS7671, except however he hadn't fused the fan down to 3A as per the fan manufacturers instructions. Now this contractor has been prosecuted.
Now how many times have you seem a bathroom fan fused down to 3A? I haven't at all, it's always just the 6A Mcb providing protection.

I think that if the manufacturer requires their equipment to be fused then they should install the relevant fuse in their equipment, then if the fuse blows it will require an electrician to change the fuse which should ensure that the reason for fuse failure is identified and rectified and that the a correctly rated replacement fuse is installed.

All the fans I've installed I've fused to 3A, as per manufacturer's instructions. I normally have those dual 1G boxes to hand for the purpose. The whole bathroom goes onto the FCU, with the fan iso along side.

This is what you need...

Didn't somebody on here mention once they had some Chinese equipment they had to install and had manufactures instructions stating that neutrals were to be fused?

Would you still follow their instructions or the standard nic reply or would you apply professionalism to the incident? Just to throw a spanner in the works....

You'd need 2 fuses unless you fuse down the whole room. Could you configure that with 2 fuses into a double box? what do the front plates look like?

The switch and fuse holder are the Click Mode range. You buy modules an fit them into the normal face plates. 4 gang face plate would be a 2 gang back box. Or you could fit the fan isolator and bathroom light switch into a 3gang plate and 2 fuse holders into a 2gang plate next to it in a dual back box.

According to there website http://www.greenwood.co.uk/media/pdfs/AXS100%20NB%20data%20sheet.pdf Greenwood AXS 100 fans do not require fusing down when fed from a 6amp mcb lighting circuit. Solves the problem I think !

^^^ Yep lets all buy Greenwood fans. In yer face Vent Axia and Xpelair

I dunno what your all going on about. There is no prosecution going on, it's just another tall story!! If anyone would get the blame (if it were true), it should be the fan manufacture. A 10/20W fan isn't going to be too well protected by a 3A HRC fuse or 6A MCB, so it's all academic, your all scaring yourself's silly, about something your not ultimately responsible for...

i'd never follow manufacturers instructions that directly contradicted bs7671.
ie use your loaf ;-)
