I have a Vectaire X-mart timer extractor that is supposed to be put through a 3amp FCU. Doesn’t mention 3 pole isolator. I was thinking of passing L, SL & N through an isolator and then feeding the L & N through a non-switchable fused unit on the way to the fan unit. Is it permissible to have a non-switchable unit in a bathroom and, if so, are there any regulations concerning zones?
As I understand it, regulations stipulate that the SL for the extractor should come from the light. I'm thinking that this may have more to do with rooms not having means of natural ventilation. The bathroom has windows, and I would prefer that the fan operated off its own switch. Could I have a FCU outside the bathroom and simply operate the fan on pull cord switch? Or perhaps even better, if I wanted to make use of the timer, take two lives off a junction box to a 3 pole pull cord isolator (again, with in-line non-switchable FU)?
Thanks in advance for thoughts and advice. I'd rather be crucified by experts than by electric bolts through my hands!
