Wire Three Way Switches
Electrical Question: My outside light will not work unless the inside light is on, is this right?
I have a 3 way switch for inside lights and an outside light switch in the same box. However, the outside light will not work unless the inside lights (on the 3 way is on) – either of the 3 way switches can be on, as long as the lights are on.
Questions, is this standard? And, should there be a way inside the box to change the wiring to allow the light switches to work independently of each other. I have 4 sets of wires coming in or going out of the box. ( I would think 1 to the other 3 way, a second to the outside light, third would be power, and 4th may go to the inside lights.) Thanks.
This electrical question came from: Tom, a Homeowner from Butler, Pennsylvania.
