Abstract
Electrical switchgear for receiving either a vacuum circuit breaker or a dummy element and including a levering-in assembly with a positional interlock bar that is operated by a levering-in block in the levering-in assembly and by a finger on the dummy element. Access to the levering-in device is blocked when the source breaker is in the connect position. A key to unlock the access is obtained by levering the source breaker or a dummy out to the test position and locking it in that position or by levering a dummy element to a connect position and locking it in that position.
