Abstract
A circuit breaker panelboard modular assembly employs a plurality of interdependent molded plastic and metal parts to multifunctionally adapt breakers of different ratings for electrical connection within the panelboard enclosure. Anti-turn connector connects the line strap terminal. Captive bolts or plug-in connections are employed to attach the breakers to the power bus. A novel concealed hinge construction is used to connect the panelboard door to the panelboard housing and the breakers are individually identified within the housing by extruded plastic circuit markers.
