A couple of test questions.
1. Why 60Vac?
2. Why does the analog voltmeter read about 6V (from gnd to neutral or gnd to hot)?

1) The hot and neutral wires will each carry about 60VAC. You will see 120VAC hot to neutral and hot to ground, though.
Cheers!

I recall answering both of those recently though the 2nd one by inference.
A1: Due to capacitive coupling between the wires forming a voltage divider.
A2: Due the the lower impedance of the analog meter "loading" the divider (Which can only handle a very small amount of current)
