Abstract: A switchgear assembly includes a first body housing a circuit breaker and a first control enclosure connected to the first body. The first control enclosure includes a first operating handle that opens and closes the circuit breaker. The switchgear assembly also includes a second body and a second control enclosure. The second body is coupled to the first body, includes a viewing window and houses a switch. The second control enclosure is connected to the second body and includes a second operating handle. The second operating handle is interlocked with the first operating handle to prevent the switch from being opened when the circuit breaker is closed. The viewing window displays an open connection for the switch when the second operating handle is in the open position and displays a closed connection for the switch when the second operating handle is in the closed position.
