While such currents would generally not be large enough to cause a fire unless they were sufficient to trip the breaker on the other side, they could still be lethal to someone touching the "disconnected" circuit. Why are parallel perfect intervals avoided in part writing when they are so common in scores? Turns out that my non-RMS meter will read DC voltage on the AC setting, but only in one direction. One days years ago, an outlet at the end of a run stopped working. I'm a trainee hydraulic engineer in Indonesia. If a circuit is run as two wires from the panel to the load, then when the breaker trips everything in the circuit will be de-energized. Light flashes on then turns off. Under load conditions, there should be some neutral-ground voltage - 2 V or a little bit less is pretty typical. 30 amp, 250 volt, 6-30R, 2-pole, 3-wire. A "live" circuit will carry the 110, an "off" circuit may carry some lower voltage. it may be that you have a faulty switch or an induced voltage that shows you have 50v on the switched live conductor.
