A power conditioner for circuit breaker panel and method of use. The apparatus comprises an electric motor electrically connected to distribution power lines into the breaker panel. The electric motor drives an electric generator. Electric power from the electric generator is fed into sector circuit breaker bus bars in the circuit breaker panel, which in turn power sector circuit breakers mounted to the sector circuit breaker bus bars. The circuit breaker panel may incorporate a main breaker between the distribution power lines and the sector circuit breaker bus bars. The apparatus may include a transmission between the motor and the generator. The method steps include using electric power from the distribution power line to run the electric motor, using the electric motor to drive the generator, and feeding power from the generator to the sector circuit breaker bus bars.
