I hope you will allow me to make a comment on your thread. I firmly believe all properties should have a RCD fitted. I'm retired now but when I was a telephone engineer - a long time ago - we often had leakage faults which would cause havoc with the old 'Party Lines'. These, if you recall, were two telephones sharing the same exchange line (one pair of wires) for speech but using a local earth for signalling. Well, as you can imagine, an earth leakage at one property could ring telephone bells in half a street! To find the culprit property we'd earth another telephone line back at the Exchange, which could be a couple of miles away and then using a connection to that earth, locate the fault by measuring the potential difference between that and the local earth. Using something as simple as a wire attached to a screw driver, we could take readings off the ground, and following the highest, get led right to the property with the leak and to the actual fault itself. Quite often faulty immersion heaters or plug in appliances. Cooker rings were a favourite. Often the owner would tell us they'd been having 'tingles' from the taps! RCD's absolutely a good idea.
