Brent,
That is indeed a possibilty. As I mentioned in an early post, AC circuits usually are connected to each other. In other words, the supply wiring willgo to a receptacle, then from there to another, etc. Did you install the dimmer switches. I am not sure if Beaver installed dimmers. These may be an after sale install. If you are going to trace this circuit, make sure you are not connected to shore power, generator, or inverter. Don't want to see you get accidentally zapped.
