"If you had been completely green".
Well, it didn't work before and it does work now. He was on the ladder for a good 15 minutes and it looked like the electronic equivalent to medical surgery. His assistant who was learning sat on the floor throughout.
One weird thing was that initially I showed the main bloke where the switch was in the kitchen for turning off the electric. Then the intricate process with the screwdriver started and only after about five minutes did I think "I don't remember him ever going back into the kitchen". So I went back and the switch was on.
I thought "this is tricky - he could have been electrocuted". I therefore asked him tentatively if he was sure that the electric was off. And he said something like "yes I've done it" or even "I've done it from here" as if to say he had negated the current in a localised way at the light source. Anyhow, I am just mightily relieved that at last it is all over. I can now go on to the next major priority which involves the hot soapy water.
If your main 'fuse' box in fact has RCD (residual current detectors) in it, he could indeed have "done it from here" by shorting the neutral (blue, new colour or black, old colour) to one of the earth wires. Not a desirable practice to to do though.
However though you saw something ON, he might have already turned off the lighting sub-circuit. He probably knew what he was doing, careless electriciand don't live long.
