    motor tripping out

    thanks everyone for being patient. Looks like the only way to be sure is to megger. I will try and borrow one tommorrow, but to clarify test the following live to ground(earth) better than 1.2 megohms neutral to ground(earth) better than 1.2 megohms and live to neutral low resistance i.e...
