Abstract
A slideably mounted insulating shield is positioned over the terminals of a secondary disconnect attached to the side wall of a circuit breaker compartment. Inserting the circuit breaker into the compartment brings the secondary disconnect terminals on the breaker into engagement with the secondary disconnect terminals in the compartment by displacing the insulating shield. Removal of the breaker from the compartment forces the insulating shield to return to position over the compartment secondary disconnect terminals thereby isolating the disconnect terminals from inadvertent contact with an operator.
Claims9
An insolation shield assembly in combination with circuit breaker compartment secondary disconnects within a circuit breaker compartment which contains a primary and a secondary source of current comprising:
- an electrically insulating shield in superposed relation to a plurality of circuit breaker compartment secondary disconnect terminals connnected with said secondary current source for isolating said compartment terminals when a circuit breaker is removed from said compartment;
- and means for moving said shield out of superposed relation to said compartment terminals for exposing said compartment terminals to a corresponding plurality of secondary disconnect terminals on said circuit breaker and for connecting said circuit breaker terminals when said circuit breaker is inserted within said compartment.
A circuit breaker compartment comprising, in combination:
- a closure for receiving a circuit breaker;
- a plurality of line and load stabs extending from a rear portion of said closure for mating with a corresponding plurality of line and load receivers extending from a rear portion of a circuit breaker;
- a plurality of compartment secondary disconnect terminals attached to a side wall of said closure for mating with a corresponding plurality of circuit breaker secondary disconnect terminals on a side portion of said circuit breaker;
- and
- a slideably mounted shield assembly attached to said closure side wall for isolating said compartment secondary disconnect terminals when said circuit breaker is moved at least partially out of said compartment.
