Fusing Fans to manufacturers spec

[nickblake]

Well chaps ive been looking at the manufacturer requirements for fusing down fans ,an every one appears to require only the permernant live to be fused so having words with those nice people at scolmore click you can do it easily with the grid range that doesnt actually look like grid fuse and an isolator in the same switch brilliant thats what i say good old Click scholmore

looks tidy.

Like that, saves messing around wiring in two different items.

How much?

 

[telectrix]

probably less than a separate isol. and FCU when you factor in 2 back boxes, never mind the extra cutting out and time running cable.

Quite agree, still like to know!

How much?

I get those isolators for about 2 quid, the faceplate for about 90p and a fused unit is around 1.50.

Never thought of doing that and been using the Click mini grid for a while now.

Nice one

The click stuff is one of the best thought out at the moment.
i like their grid stuff as well.even on normal plates you can swap a 2way for an intermediate easily.

This may sound a silly question but how to you wire it if you're using a fan with an over run timer?

 

[telectrix]

as i see it, it's a 3 pole isolator with a fuse in the permanent L.

Perm feed through fuse, into isolator then out to fan. Neutral and switched into the out of isolator.

According to the manufacturers instructions i have read you only need to fuse down the permernant feed and not the switch feed , so ideal in my mind ill let you know the cost

Yep, perm live only on the ones I've seen. I've also noticed that the rule about fusing it only applies to the UK! Anyone know why we're blessed with that requirement here and no one else is?

It is a bit strange, as the whole circuit is protected at 6a. That isolator with integrated fuse on the perm live is a simple but great idea, as said saves the hassle of having to use two accessories. Why does the perm live need fusing down but not the switched live?

They're both fused because of the way it's suggested to be fed (via the perm live). If no other countries need to add protection, then why do we? I don't believe other countries lighting is 3A to start with. I wonder if it's a misunderstanding that has been propogated across the chinese manuf plants.
