No the instructions ask for the permanent line to be fused before the split to permanent and switched so not at the fan.

I can see both sides for the fusing of both lines. Was the fuse brought in due to motors burning out and causing fires? If that's the case then only the perm L needs fusing as the SL is only a signal to the PCB as any fault should cause overload on the perm L. Or is my logic way out? Ideally what is needed is a three pole fused switch.
Always stick an isolator in when doing a new fan, makes it easier for testing and working on and fans annoy me when I go for a gush at three in the morning and it wants to runs on for twenty minutes hence I give the customer the option of where they want it... :lol:
I believe only the permanent live needs fusing as the switch live just 'switches' the actual fan motor only ever runs off of the permanent live. They don't really care about the fuse blowing and leaving a permanent feed at the fan.
Saying that though, I have yet to see a fused fan in a house.
Come and look at some of the houses in Dorset then.I believe only the permanent live needs fusing as the switch live just 'switches' the actual fan motor only ever runs off of the permanent live. They don't really care about the fuse blowing and leaving a permanent feed at the fan.

could someone let me know which makes of timed fan only require the perm Line to be fused as all the ones i fit are the same as in post 24 that shows both perm and switched needing fusing. Would be nice to not have to put the light on the fuse as well.
Try making the fan work with just the switched live and neutral!
I assume the perm line actually feeds the motor etc. and makes the switched live useless if not present.
