An adjustable height spacer for providing rigid support and insulation between the bus bars of an electrical panel. The spacer is adjustable in height to provide various distances between the bus bars. The spacer includes a pair of body members that are axially aligned. A repeating series of teeth of various heights is defined around the margin of each body member at one end. The teeth are configured such that when the toothed ends of two body members having identical tooth patterns are mated, the teeth operatively engage each other to provide a secure coupling when the body member is placed under a compressive force. The height of the body member is varied by rotating one body member with respect to the cooperating body member such that a selected set of teeth within the series is engaged.

An electrical enclosure having continuous front accessible dedicated wiring compartments. The dedicated wiring compartments provide the installer with easily accessible front wiring compartments. Each dedicated wiring compartment contains wiring for a specific function. The dedicated wiring compartments are configured to provide a continuous front accessible wiring compartment for multiple enclosures installed immediately adjacent one another. Horizontal frame members of the electrical enclosure provide a significant part of each dedicated wiring compartment.

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.
