In testing some switches in a home I was found a bad 4 way switch. But was picking up some weird voltages from the 3-ways feeding the 4-way, about 50 volts, but not enough current to light anything, just my little neon tester and Fluke meter. Don't know where this was coming from, maybe the wires were coiled up between the runs causing a coil-like (inductance effect) inducing some voltages. Any ideas?
The Golden Rule - "The man with the gold makes the rule"
once at work i hat opened the breaker of a receptacle line for servicing. with the small neon screwdriver tester, i could see no difference between breaker on and breaker off. measuring with a tester with coil to montior the voltage then showed me the line was off.
Background: The cable was running in a troughing with several others. as both ends of the phase conductor were unconnected, the wire collected the field fromt he others...
