Re: How much DC on your mains ?
All I know is that I've recently been contacted by the electricity supplier of a non-residential property with which I'm involved wishing to replace our meter with a "smart" metering system - which I assume must involve meter-reading signals travelling back and forth through the grid between our property and their monitoring centre.
