I get mixed answers on this and wondered if I can get some help: Is it allowed to fit a three pole isolator switch (not cord operated) in zone 3 of a bath / shower room?
Well my answer is that as there are only zones 0,1 and 2 , then zone 3 would be fine.
If your thinking zone 3 (16th edition) which is now zone 2 (17th Edition), then I'm afraid you can't, unless the switch is for a SELV circuit or is a shaver supply
