Abstract

An exemplary circuit breaker terminal cover includes a cover and at least one attachment portion. The cover has first and second side walls and a vented surface extending between the first and second side walls, the first and second side walls extending to form a wire opening. The at least one attachment portion is configured to hold the terminal cover in place and to removably engage at least one of an opening, a side, an edge, a protrusion, a fastener, a wire, and a handle. An exemplary strip of circuit breaker terminal covers includes a plurality of terminal covers and at least one frangible connection joining two adjacent terminal covers of the plurality of terminal covers.

14. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion comprises a plurality of hooked members.

15. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion comprises a plurality of projections configured to slideably engage an exterior surface of a wire such that it can slide along the wire a first direction but resists movement in a second direction.

16. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion is configured to engage and be secured by a wire locking screw.

17. The strip of circuit breaker terminal covers of claim 11 , wherein the cover includes a flexible door configured to provide access through the cover.

18. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion comprises a recess configured to receive a screw head.

19. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion comprises a projection configured to engage a recess of a screw head.

20. The strip of circuit breaker terminal covers of claim 11 , wherein the attachment portion is formed by the first and second side walls of the cover, the first and second side walls being spaced apart such that friction against the side walls holds the terminal cover in place.

21. A method for using a strip of circuit breaker terminal covers, comprising:

providing a first strip of terminal covers each comprising:

a plurality of terminal covers comprising a cover having first and second side walls, a vented surface extending between the first and second side walls, the first and second side walls extending to form a wire opening, a barrier extending between the first and second side walls that separates the vented surface from the wire opening, and at least one attachment portion configured to hold the terminal cover in place and to removably engage at least one of an opening, a side, an edge, a protrusion, a fastener, a wire, and a handle; and

at least one frangible connection joining two adjacent terminal covers of the plurality of terminal covers;

separating two adjacent terminal covers along the frangible connection to form a second strip of terminal covers that is shorter than the first strip of terminal covers; and

attaching the second strip of terminal covers to a plurality of circuit breakers.

22. The circuit breaker terminal cover of claim 1 , wherein the cover is integrally molded in one piece.

23. The circuit breaker terminal cover of claim 11 , wherein the strip of covers is integrally molded in one piece.
