I would like to have a bathroom fan heater fitted on the wall in the bathroom. My father, who's a retired electrician said that it is legal to have an isolation switch in the bathroom, near the heater. I was wandering if this is still true, or if he is outdated. Can an isolation switch go inside the bathroom or does it have to go outside. Also, can a junction box go in a bathroom or does this have to go outside.
Any help much appreciated. Thanks.
