induced current.. i think

That would cause far too many other issues to just have this as a fault.

Current can't flow without potential.

The guy is measuring with the same type of instrument the previous testers used. My money, it's an issue with the meter.

I was thinking.. is the current flowing in the neutral conductor from other supplies? I have seen boards with quite high voltages on the neutral even with the board isolated.. all due to a neutral not being bonded
