Circuit breaker with improved tie-down accessory

An electrical panelboard containing one or more electrical circuit breakers equipped with one or more tie-down devices to secure the circuit breakers to the panelboard, each of the circuit breakers including a housing having a raised portion that forms a top surface extending between a pair of end walls and a respective slot at the base of each of said end walls, and said panelboard including one or more mounts for attaching said tie-down devices to said panelboard, each of said mounts including a fastener with a rounded head attached to a stem, each of said tie-down devices comprising:

• a breaker-attachment portion adapted to be mounted on the circuit breaker housing around said raised portion such that the top surface of said raised portion of the circuit breaker housing is unobstructed by said tie-down device, said breaker-attachment portion having a pair of mounting hooks that fit into said slots of said raised portion to thereby attach said tie-down device to said circuit breaker housing, and
• a panelboard attachment portion extending beyond said circuit breaker housing and adapted to attach to said panelboard mount, said panelboard attachment portion including a hole with one or more slots extending from the hole such that the hole expands when pressed concentrically onto said rounded head of said fastener and then contracts so that said panelboard attachment portion attaches to said mount beneath said rounded head and adjacent said stem.
