After a couple of false starts in replacing my extractor fan, I\'ve finally gotten round to doing it. My problem, before I get started and find myself caught short (Having looked through the forums, this seems to be a common symptom), is thus:
The fan will run of a standard setup for an NDX100T Timed fan, the destructions say that there should be a double pole isolating switch where the Neutral runs to the fan/light, the live runs from the double pole to the light switch and then to the fan, and the live switch runs from the light switch to the light and then the fan.
My question is that as far as I can see (no roof access as I'm in a middle floor flat) there is no double pole isolating switch unless it is the light switch. Assuming that it is a double pole switch, can I safely run the live from it or will I need to install another double pole?
On the other hand (I think the answer to this one will be a NO), if it's not a double pole, will it be safe to ignore it's absence or would it be best to install one?
Thanks for any advice given, I hope I've not confused anyone with my description!
