CLOSED TRANSITION AUTOMATIC TRANSFER SWITCH ASSEMBLY AND ASSOCIATED METHOD

The disclosed concept provides for a closed transition automatic transfer switch assembly having only two switch assemblies. This system utilizes a first switch assembly and a bypass switch assembly. The switch assemblies are each physically coupled to two power sources as well as the system load. The switch assemblies each include a power actuated contact arm. Each contact arm is coupled to, and in electrical communication with, the system load. Each contact arm may further be placed in one of the following configuration; a first configuration wherein the contact arm couples, and provides electrical communication between, the first source and the system load conductor, a second configuration wherein the contact arm couples, and provides electrical communication between, the second source and the system load conductor, and a neutral configuration wherein neither the first source nor the second source is coupled to, and in electrical communication with, the system load conductor.
