[quote author=braychurchmouse link=1107263245/0#0 date=1107263245]Hi, could anybody point me to Regulations (in simple terms) re use of this. ie why is it
3 pole...does this mean it disconnects earth

Firstly I don't believe this is a requirement of BS 7671, more a new requirement that NICEIC have set
We never disconnect the earth, earth always remains connected, the 3-poles are for a permanent live, a switched live, and a neutral
Quote:For bathroom use I was just planning to put a two pole isolating switch OUTSIDE bathroom, but my local TLC says this 3 pole switch should be INSIDE bathroom ...and not to bother anyway unless its new build.
3-Pole isolators are for fan's with a timer usually, the isolator switch should be located outside the bathroom e.g. above door, I don't think you can put one inside the bathroom and still comply with BS7671 bathroom zones
Quote: I tried Googling "BS 3676" "BS EN 60947-3" but I just get list of people making or selling the switch. Also tried http://www.iee.org/Publish/WireRegs/bs7671.cfm but got myself lost!!
Here's a link to a 3-pole fan isolater

Enables repair or routine maintenance of fans. 240V only.For full details of compliance with BS EN 60947-3 see Technical Data page 107. "
Yep, for local isolation to conduct maintenance or repair, usually for use with timers, but use them for what you like
