Do bathroom extractor fans need to have isolation switches for building control?
Aye they do tbqh
Yup, think it's building regs, rather than lecky regs?
Building regs Part F (ventilation) will specify the extract rate and any over-run requirements.
Building regs Part P will determine the standard that the electrics should be installed to. That says BS7671 is the recomended way to go.
Also following the manufacturers instructions will be included.
quite a few require fuse protection at 3A as well
...so it's best to run your whole bathroom lighting/fan ctt off it's own fcu with a 3a fuse in it. I mean so long as your bathroom isn't wanting the Blackpool illuminations in it.
Now why didn't I think of that...bought an FCU and 3 pole isolator for the fan, but could just put the whole lot on the FCU 3 pole isolator ain't cheap either...can return it to our hosts.
