    Finding earth leakage on 3 phase supply cables?

    Hi. I've got a high earth leakage value on a main db supplying many 3phase cables. What's the best way to find the leakage values on each cable? Some of them can't be turned off. If I clamp around all 4 live conductors as they enter the db would this give me the earth leakage?

    RCD tripping dilemma

    Hi all, Cam across a tripping 63A RCD, which is protecting pretty much everything in an office and even the lighting! The first guy who came out seemed to think that perhaps a spur feeding a AC unit was the culprit and proceeded to change it over, but I didn't really see the point in that. I...

I have come across a radial circuit (supplying socket outlets) which, when supposedly isolated (mcb off and all cables free), is still showing 37 volts LE LN. I have found that the voltage is reduced to zero by switching off one of...
