Re: Source impedance of mains, a workaround?
Phil: that's all interesting stuff. Thank you. Yes, I can see why earth loop impedances are low in London - (as noted, not only do I live 1KM from a main Siemens sub-station, but 5 metres away from the building's distribution busbar. All good points about the MCB - I leave my MCB well alone and only re-set it when I know what the fault condition is!
