Default Re: How much DC on your mains ?

Well Hannahs Radios, I'm not going to reveal the innards of what is known in the electrical supply industry as a "Black Box" on an open Forum. Its illegal, and affects us all because Revenue Protection is financed by our electricity bills. It was part of my job for a number of years to catch electricity theft scallywags.
Plans have been afoot for a number of years by gas, water, and electricity utilities, to utilise the mains cabling for metering data transmissions. I even heard somewhere that internet trials have commenced. But you'd better ask Forum guys with Telecomms expertise about that.

Regards, David
