So your local Home Depot, Lowe's, Target, Walmart have dual switch all around the store? :smile:
My point is I think there is more then what your telling us. :smile:
Well there is, the CA energy code is as large as the NEC. The switching can be controlled by a ceritified control device, but you are still required to have over ride swithces, the floor area is one area and the lighting is required to be able to be reduced 50% in a uniform manner. the lunch room, bathrooms, offices, etc are all required to have seperate switching.
If you have sky lights, which are now required in larger building, then you have daylight switching requirements, which my be switched seperatly from the other switches.
My point is, you cannot use the breakers as a switch, unless it is located in the area in which the lights you are controling are also located in that area, and you would need two circuits to get you bi-level switching.
