The present invention provides a mounting system for circuit breakers in an electrical panelboard assembly. The base and cover forming the circuit breaker casing has an integral foot extending from a bottom side. The foot is angled and has a notch on a side forming an acute angle with the bottom. The panelboard assembly has a bus cover adapted with a opening or opening to receive the foot. This secures the circuit breaker on one end, and a screw into a bus secures the circuit breaker on an opposing end. The bus cover has a rail which engages the notch in the foot. On an opposing side of the foot, a spring engages the foot and forces the foot into the rail. The spring is an integral part of the bus cover and is cantilevered at an angle to the main body of the bus cover. Ledges are formed integrally into the bus cover on opposing sides of the spring. The ledges prevent overstressing the spring while inserting the foot during installation of the circuit breaker.
A panelboard assembly, comprising:
A circuit breaker for interrupting power in a circuit path between a source and a load, comprising:
A bus cover secured in a panelboard assembly for covering a plurality of exposed bus bars, the panelboard assembly having a plurality of individual circuit breakers, wherein each circuit breaker is electrically connected to a bus bar and the bus cover is disposed between the bus bar and a bottom side of the circuit breaker, the bottom side of the circuit breaker having an extending member, the bus cover having:
A method of making a panelboard assembly, comprising:
