hark said:I have an FCU in the hall outside my bathroom, feeding a pump in the bathroom. Can I use the same FCU to feed an extractor fan and a shaver socket, if I run cable from the FCU to their locations in the bathroom?
FWL_Engineer said:You should never run shaver points or fans in bathroom from a ring main spur or a radial circuit for other purposes.

Sorry missed something.......why?
Breezer - what pipme said was "2 pole FCU could be used to supply the bathroom spur for simple lighting and fan, now all lives on that spur are protected at 3 amp"breezer said:you can not do as you suggest because with a timed fan it needs a switched live to make it work, agreed?
the switched live comes from the lighting circuit, agreed?
so how are you going to isolate the fan supply with a fcu that at best can only isolate 2 poles, , if you use it to isolate the lives you are not isolating it as the neutral is still connected, so if yo isolate the neytral which live do you isolate, and if you dont you can back feed into the lights so they will work when off and vice versa.
But yes, this is much better. Pipme - if you are concerned about how to fuse at 3A, why not have an unswitched FCU supplying the light in the bathroom, and then the normal wiring via 3-pole isolation switch to the fan?breezer said:extrator fans should be wired from lighting circuit, and have a 3 pole isolation switch
You said it.....Normally all lighting and bathroom fans are fed via the lighting circuit, this is irrelevent
