Wonder if anyone can help here. I have a new extractor, a1.5kW Jet thing. Secondhand but good nick. It's plugged into a 13A socket (motor name plate says 4.8A) and runs just fine starting up and for long periods. However, it trips the RCD a few seconds after switching off as it's spinning down. The socket is controlled by two switches which are wired '2 ways', so either will switch it on or off, just like how light switches are wired up.
I thought the problem could be the motor generating current into the neutral while spinning down, or perhaps something to do with a build up of static. The old extractor was fine with this arrangement, although only 750W.
The earth is always connected, and only the live is switched. Do I need a double pole switch so both live and neutral are switched, if the problem is do to with the neutral being connected whilst spinning down?
Cheers!
