This question already has an answer here:

So I have a three switch box and one goes to a light/receptacle outlet on the wall. The other two go to my ceiling fan. When I read the wires out when they are switched off I get 0vac. When I turn on the switch circuit that I'm not reading with my meter, I get anywhere from 28-36vac, then I turn on the switch that I'm connected to with my meter I get 115vac. Why am I getting the 28-36vac on my meter when I'm flipping the other switch on and off? The wall receptacle does not have any effect on the voltage in the ceiling.

  • Which wires are you measuring between? – ThreePhaseEel Jul 1 at 22:42
  • Can you plug any sort of load into the circuit? A night-light would do (as long as it's turned on). Then test again. Let us know if that voltage goes away. – Harper Jul 2 at 3:07
  • Phantom voltage is what you need to look up. There are several questions about it. – JPhi1618 Jul 2 at 14:17

    Meter reading without a load are meaningless. You need at least a small load, e.g. 100 kilohm resistor across the meter probes, to get a useful reading. – DrMoishe Pippik Jul 3 at 0:11
