[Sounds like your safety switch is imbalanced.......]@ bright eyes. would this be a landing 2 way light that's tripping ther RCD/s?
You reckon the call out charge might be a little excessive? The scenery is quite good if you like bikinis on white sandy beaches. And the unemployment rate here is zero.haha were australia
Can't say I have seen this sort of problem before,on a lighting circuit. but I would firstly insulation test the wires from the switch to the light and back to the CU. I had a similar problem with a ring circuit, it turned out to be a slight defect/thinning on the basic insulation covering the neutral, you couldn't neutral see it it was about 400mm further up the sheathing, manufacturing defect. The RCD would hold then trip when an a load was switched on, I had changed the CU to a split load double RCD by the way, it must have been like that since the house was built, but obviously not enough fault current to burn the fuse wire. Maybe you should check that the neutral at the CU for that circuit is terminated in the correct bank of Neutrals for the correct RCD Live in RCD A and neutral in RCD B That may explain the other tripping.This house has two lighting circuits and each has an RCD (safety switch?). No problems on any power circuits in the house but one light fitting trips the RCD when light switch is turned on. It does not trip if there is no light bulb in the socket. Obviously all the lights on that circuit go out but lights on the other circuit stay on. If the RCD is returned to the on position then the other RCD trips. It seems that it only trips once current has reached the neutral side of the light socket. No wiring in this house is old or appears to have any damage. Has anyone seen this type of problem before? Thanks - all comments and theories welcome.
Thanks Rich
I always use licensed electrical contractors. Here in Oz it is illegal to so much as fit a three pin plug to a lead unless you are a licensed electrical contractor, not just an electrician. In fact many appliances need to be "tagged" every three months in the work situation, especially tradesman's tools.
I am a building supervisor and work closely with electricians, sometimes as many as 60 on a job, so I greatly respect our licensing system and the fact that it is quite unusual to find anyone doing their own work illegally (usually it is only English emigrants).
The problem only surfaced when an electrician fitted the two RCD's and he was unable to diagnose the cause of the fault. When I saw your forum I thought these guys will have seen this before and know the cause of the fault particularly since the symptoms are so specific but it seems not.
Thanks again for the response. Neil.
unless bacon butties laced with heroin will help
has any one else had this sort of thing happen ?
