Is a Fan isolator required

[Andy78]

Not sure I'd like to argue that in front of a Coroner's court.
Fortunately, in the case I referred to, no Coroners were involved, although the property in question received serious damage to its roof, and presumably, water damage throughout the rest of the house.
I normally only fit triple pole fan isolators alongside in line fans in lofts, and supply the whole lighting circuit to the bathroom through a switched FCU, fitted with a 3A fuse as per most manufacturers instructions.
Wall mounted fans, which I try to avoid because of their comparatively poor extraction rate and noise, just get the switched FCU.

Not sure I'd like to be a manufacturer in court explaining why the product I had designed and sold did not have adequate protection for its design.

Agree Andy, but it doesn't seem to stop them. Many extractor fans and dryers are still made without thermal overloads, which is strange given their proximity to dust and fluff that jams them from time to time.
