You weren't bothered at all by his saying he measured 30 volts between
neutral and ground?

Not if he measured it with a digital meter, no.

_Even_ with a digital meter. Hint: neutral and ground are _supposed_ to be
shorted together at the panel. Unless there's a break in the neutral or ground,
even a digital meter shouldn't see that much difference between ground and
neutral.

Showing 30V hot to ground or neutral, when the breaker is off, is where the
impedance of the meter matters.

[Worst case difference between neutral and ground, assuming the circuit
is in operation is about 1.5% (allowable voltage drop at full current
thru the neutral).]

The OP's measurement of .7ma is also too high for impedance effects. It'd
be a few microamps or less.
