[QUOTE="binky, post: 453644, member: 490"] [USER=7]@steptoe[/USER] will be happy then :D I've often wondered about conductivity of building materials. Solar Inverters can detect earth leakage on the DC side ( ie the panels) of less less than 20mA. Given that roof timbers are ( should be ) bone dry, bricks etc etc bone dry, how the hell does it find an earth path to a slightly damp DC connector on the roof???? It's puzzled me for years.
