which is hot


I meant the wet fingers on BOTH wires trick in my earlier post. I'm pretty sure that's never a good idea.
I didn't know about the "wet finger on one probe, other probe on a wire" trick. Cool. I might need that one day.

Without going into the specifics of how electrical testers work, I can assure you that this method is safe. Just be sure you have it set on the voltage scale not the amperage scale.

the voltmeter employs a shunt resistor and passes virtually no current (otherwise it would load down what you were testing and change the voltage)

... that doesn't make it safe or a good idea though... but to each his own!
