electric trip switch

by **Ralph** » Mon Aug 13, 2007 2:22 pm

I just have had a new conservary installed, which included 3 power points. As part of the new regulations the electrian tried to install a trip switch, between the main fuse box and the electric meter. The switch kepted tripping !!!. I pulled out all the plugs, but it still kept tripping. Any ideas what to do next.

Hi Ralph, first of all don't blame the leckie! the RCD has just shown up a long standing problem which will need a leckie with an Insulation tester to find.
He will need to seperate all Neutrals from Consumer unit common bar to test each circuit in turn with all circuits switched off/fuses pulled, sorry but not really in the realms of DIY, but should not take long to identify 'duff' circuit[s], most often ring with earth touching Neutral, possibly skt fixing screw against cable, good sparky should find quite soon,
regards SPARX

Thanks, leckie found problem today, which was a double 3 point power switch. The wires were very loose, leckie spotted them, tighten up and trip switch works OK. The 3 point plug being used for a floor stand light, with no problems.

Took the two leckies 1.5 hours to find fault and re-store all plus etc.

Thanks
