3 way switch voltage on off wire is it normal to observe some voltage 25 50 volts when a three way switch connection is off perhaps as a result of some electromagnetic or some other phenomenon. There is a way of wiring a three way switch not to code any more that uses two different live circuits on the same side of the 120 normally it was used from building to building but any thing is possible so it is possible to have the light off and both switches off and have a full 120 volt potential on a three way circuit.

3 way switch voltage when off. The light turned off so i was sure there was no power. The first time i was replacing a light fixture and i was the only one in the house so i just turned off the 3 way switch before getting to work. Either way complete these five steps for 3 way light switch wiring. Or is the presence of such a voltage an indication of some type of short or other problem in my wiring that needs to be fixed. Hi guys ive encountered this problem twice now. Disconnect all three wires or four if the outlet is grounded.
However when i turn the switches off my volt meter shows either 36 or 38 volts depending which switch is used on the wires at the end of the cable run where my fixture will go. With lights off im getting varying voltages of 34 to 60 volts. Voltage present after switch turned off re. 2 turn the power back on. Add an electrical box for the second 3 way switch in the basement. I dont know why i bothered to check the voltage before putting the new fixture on and after taking the old one off but i did and it read 123v when on good obviously but it read 38v when turned off.
Now using your multimeter you are going to determine which of the three colored wires is. 1 turn off the power to the circuit at the main panel. 3 install the first. In the dining room it is the same with two 3 way switches. Its likely youll also need to replace the existing switch box with a larger one to accommodate the extra wires for the 3 way switch. Turn off the correct circuit at your electrical panel.
Where is this voltage coming from and how much voltage is acceptable when 3 way switches are turned off. Approximately 23 volts in one of the fixtures. This is a circuit with two 3 way switches and one 4 way switch controlling a ceiling fan with light. When the switches are off the led lights still burn very dimly. I have a 3 way circuit providing current to 4 recessed led lights. I disconnected all of the wires and checked the switches and they worked perfectly fine complete discontinuity when broken.
Other than that is it a 3 way switch or is the light wired with 2 switches in series ie can the light be controlled by either switch regardless of the position of the other switch. Identifying the common wires. 3 way circuit with voltage in the off position. However the fan and lights work normally as they should.
