A receptacle assembly includes a housing having an interior chamber, a switch mechanism movably mounted to the housing and having a portion extending into the interior chamber with the switch mechanism capable of being moved relative to the housing and switched between OFF and ON positions, a receptacle body spaced from the switch mechanism and mounted to the housing with receptacle body having an interior cavity in which a plug can be inserted into the receptacle body, and an internal interlock mechanism supported within the interior chamber of the housing and extending between the interior cavity of the receptacle body and the portion of the switch mechanism extending into the interior chamber of the housing. The interlock mechanism is rotatable between unlocked and locked positions relative to the receptacle body and relative to the portion of the switch mechanism such that the interlock mechanism when in the locked position relative to the receptacle body and concurrently in the unlocked position relative to the switch mechanism prevents removal of a plug from the receptacle body after the switch mechanism has been switched to the ON position, whereas the interlock mechanism when in the unlocked position relative to the receptacle body and concurrently in the locked position relative to the switch mechanism prevents switching of the switch mechanism from the OFF position to the ON position once a plug is allowed to be removed from or reinserted into the receptacle body.

A motorized racking operator for racking a circuit breaker into and out of electrical switchgear is disclosed. The racking operator includes a motor, an On-Off control in signal communication with the motor, an anti-rotation bracket securely attached to the motor, and a latch. The motor has a drive shaft with an end configured to operably engage with a receiving end of a racking shaft. The latch serves to removably secure the motor and bracket to the circuit breaker such that the motor and bracket move in unison with the circuit breaker in response to the motor driving the racking shaft to rack the circuit breaker into and out of the switchgear. The anti-rotation surface of the bracket engages with a surface of the circuit breaker to prevent rotation of the motor in response to the motor applying a torque to the racking shaft.

A bus assembly for switchgear includes a pair of elongated members each of an L-shaped cross section with a lateral side and a transverse side integral with the lateral side. The elongated members are positioned in a juxtaposed spaced apart relationship forming a hollow rectangular tube wherein the lateral sides are generally parallel to each other and the transverse sides are generally parallel to each other. Support members connected to the lateral sides may be U-shaped components engaging lateral exterior sides of the elongated members and may be connected to an element having flange which extends from the bases of the U-shaped components for connection to a horizontal bus bar. A connecting device may be provided with separated extending legs adapted for attachment to components of a laminated horizontal bus member.
