I'd like to wire the shower room extractor fan from the shower

found some info where one person said it's a no-no under current
wiring regs but could be done via a contactor, and another says it
can be done without a contactor as long as it goes via a fused spur
from the shower switch.

Any electricians here can tell me which is the legal way to do it as
I'd like to do it through a fused spur from the shower pull switch
for simplicity..

You can do it with a fused spur from the shower isolator switch it you
want. You should label it at the consumer unit to avoid surprises for
later maintainers. Also since you would be removing all power from the
fan when you turn the switch off, you would lose any ability to have a
an automatically timed run on after the shower.


Could he wire it from the supply side of the shower switch & avoid
that?
