No, only on one occassion mentioned in the other thread, have i had a problem where the e/l unit kept tripping once replaced. I just didnt have time to trace an intermitant fault, i do believe however that the problem was down at the gate, where there are lights, a plug and a gate motor. The second opinion fella decided to strip and disconnect, it was out of my hands.

The problem with tracing faults, it can take days, trying to get people to pay for this time has proved to be quite a challenge, especially once the fault is found and repaired, the customer cant understand why it takes you so long to dig holes and follow cable routes, break walls open because some tosser tapes up a joint and plasters it directly into the wall, bury flat twin +e in a kitchen, then the cupboards are fitted and they drill through the wire, but it doesnt trip straight away because it just cuts the insulation, etc.
