6a fan isolater or 5a fused connection unit for bathroom fans

[baazab]

hi avery1 i notice few new houses got 5a fused connection unit controlling bath room fans,my q how do they do it if you have 3core cable +earth (timer fan) i always used (3polefan isolater l1 l2 N).:dozey:

Manrose how about you? They specify a 3a Dp fused spur before the light switch so like tel said the whole lot would be on the fcu

That nice company who's instructions state a DP isolator and 3A fuse requirement?

Careful with your innuendo! There could be delicate females, DIY'ers or young apprentices reading this thread ........ :wink5:

They gotta learn sometime! :biggrin5:

I don't get it! Is that a question or a statement?

A bit of both lol. Wish I'd written it a bit better now! Actually I've just read a set of Manrose instructions and it doesn't state before the light or anything sensible.

What I want is a fan which doesn't need a fuse!! Now that would be good.

fitted a elv fan in shower room today. no mention of fusing in the manufacturers leaflet. i'll be back there friday and see if i can pick up the data, as also the fan was virtually silent. well impressed , especially as the builder supplied it.!!

That would be perfect! But i believe its asking too much of these manufacturers, i don't see the need for additional fusing just for a pigging bathroom fan! Have a look at these http://www.tlc-direct.co.uk/Technical/DataSheets/Manrose/BGCF100_200.pdf

Except this asks for a 3A fuse and DP isolation!

whole issue is quite pointless as a 6A MCB would trip while the 3A fuse was thinking about it.

That's what i said earlier, it asks for 3A dp isolation and if you look at that poxy little diagram its installed before the light switch, not very clear though and i wouldn't arse about with that anyway when a tp isolator is a much better way to go

 

[Guest55]

Is there any fans out there that DON'T specify 3A fuse protection?

yes , at least 2.

greenwood for 1 , the other make escapes memory but is another well known brand

But it probably would have been blocked by the forums bad word detector!

That old cookie! So what do you do for 'light' when working on the light(s) in the bathroom ......

Set fire to the bog roll

Ooh i love a mass debate! There is no requirement unless the manufacturer specifies it, i rarely fit an fcu, just the tp fan isolator will do in my eyes. The fcu would only be needed for the permenant live as that is what runs the fan motor, the switch live is just to trigger it if its a timer fan that is! If its not a timer fan then just an fcu would do the job as there would be no permenant live anyway!

When I was (much) younger, my Mum said if I didn't stop doing that I would go blind. Dad said I would go deaf.

Here I am all these years later, wearing glasses and booked-in for a hearing test next week.

Ah it's nice to see some of the old wives tales, myths and general heresay regarding bathroom fans rearing their heads again. Here's one for all you lot, I fit Soler & Palau fans whose manufacturers instructions don't require any form of fusing down. I am fully entitled to feed my fan from a light switch without a single fuse or a TP isolator in line and my work in doing so would be completely and utterly acceptable.

"Gotta have a TP isolator for maintenence in the dark"... Hogwash!
"Gotta have local isolation"... Tripe!
"Gotta fuse it down to 3A"... Claptrap!

Keep peddling these myths boys, it does the industry so many favours you know!

He's quick on his toes with replying to posts! :biggrin5:

Agreed - he is extremely quick

I always have to think a post over a bit before submitting in case I've made some kind of howling schoolboy error - resulting in having to survive the inevitable onslaught of 'friendly' abuse and banter!!
