Description: |
| Abstract:
Disclosed is an interlock system for the access doors of an electrical control cabinet. The power to the cabinet is controlled by an externally actuable circuit breaker, which in turn is controlled by an actuator mechanism operatively coupled to each of the access doors of the cabinet. There is provided means for inhibiting the actuator mechanism and preventing the application of power to the cabinet when any of the access doors are open as well as means for securing the access doors in a closed position when power is applied to the cabinet, irrespective of the order in which the doors become closed. The interlock mechanism for each of the access doors may be selectively defeated to allow access to the contents of the cabinet while the power is still applied. |
