Here's the scoop:
There are 3 switches in my hallway. One switch on side A and two switches on side B. Side A switch controls same light as one switch on Side B. I replaced the switch on Side A and now, when the switches are in a certain configuration, you can hear a buzzing sound and then the circuit trips within 10-15 seconds.
I feel like its a grounding issue, but I don't want to touch anything till I'm sure. The switches all work as they should except for when a specific configuration of on/off exists, the circuit goes haywire.
Any ideas on what the problem is given that a buzzing sound happens and then the circuit trips?
There are two lights, switch A and switch B1 control one light, and switch B2 controls a separate light
The wiring/power source is unknown - could come from the 2 switches at opposite end of hall.
The switch had to be replaced due to physical damage of the switching mechanism
