Just how many times can a person do the same test and get the same results without trying something different?
Another walking distance job from Sunrays house. Customer had a water leak very early Sunday morning resulting in water running out of light fittings, he described as: "The clicker switch thingy in the fuse box won't go back on."
My boss assumed RCD covering several circuits and my brief was to make temporaries/disconnect to get some power back on.
Armed with basic tools including non calibrated insulation tester and some random lengths of cable, I found there were no signs of drips and everything was drying nicely, the emergency plumber attended to stop the flood and repaired on Monday morning. He told Customer it would dry out and the electrics would reset the following day.
The 'clicker switch thingy' is a 6A, in all RCBO 5way CU, for all the lights in a little 2 bed terrace. He demonstrated twice that it trips instantly when reset, I must have tested N&L to E half a dozen times and found nothing, well about 8MΩ. I opened the 3 fittings he reckoned the water was coming out of and only found water evidence in one and even that was dry. I was so intent on the issue being water It stupidly took more than half hour before it occurred to me to test N to L and found a short which was very quickly found to be a faulty bedroom LED.
