ABSTRACT:
A transfer switch is provided for transferring the supply of electrical power to a load between a utility source and a generator that generates electrical power when started. The load is interconnected to the utility source through a first circuit breaker and to the generator through a second circuit breaker. Each circuit breaker is movable between an on position and an off position. The transfer switch includes a first arm movable between a first position and a second position wherein the first arm is engageable with the first circuit breaker for moving the first circuit breaker from the off position to the on position. A second arm is movable between a first position and a second position engageable with the second circuit breaker for moving the second circuit breaker from the off position to the on position. A control structure selectively urges the first and second arms to the second positions.
