Abstract: The present disclosure relates to a system of assemblies for remotely actuating a tap box to a continuous access busway. The system includes a tap box having a male component with electric contacts positionable between an engaged position and a disengaged position with a continuous access busway. A remote actuator interface positioned along the tap box for being selectively attached to a remote actuator device for manipulating the male component between the engaged position and the disengaged position. The remote actuator device may be a powered actuator device or an elongated control rod wherein the powered actuator device and elongated control rod may be selectively coupled to the remote actuator interface to manipulate the male component between the engaged position and the disengaged position relative to the continuous access busway from a safe distance to reduce the event of injury due to arch flashing or electrocution.

Abstract: A vacuum-type electrical switching apparatus (10) for high voltage electrical power. A vacuum pressure condition in a vacuum pressure space (21) surrounding electrical contact points (18) is monitored and movement of the contact points between open and closed positions is automatically prevented when the pressure exceeds a predetermined threshold in order to avoid destructive arcing between the points. A sensor (32) provides a vacuum signal (34) responsive to the vacuum pressure condition. A controller (36) automatically inhibits movements of the contact points when the vacuum signal indicates that the vacuum has degraded. A contactor (38) may be placed in series with power supply (28) and a solenoid (24) used to move the contact points, with the contactor being automatically opened by the controller in response to the degraded vacuum condition.
