Bathroom extractor fan low voltage

geome · 2 Apr 2016

I am fitting a low voltage extractor in the bathroom wired to the ceiling rose can I fit an on/off switch to the fan on the low voltage side of the transformer to switch the fan on and off.

You could but the transformer would always be on.

You probably mean extra low voltage i.e. 12v. It is better to switch the mains side of the transformer.

Yes thinking about it
It makes sense to wire it on the ac side
