摘要： A busway and a method of assembling the same in which a flowable, uncured epoxy is applied between insulated busbar conductors that are stacked on top of one another and inner surfaces of the busway housing into which the stacked conductors are placed to form an enclosed busway. The busbar conductors are insulated by an epoxy powder coat, which can develop pinholes during the curing of the epoxy powder. A flowable, curable dielectric material, such as epoxy, is applied between the outermost busbar conductors and the inner surfaces of the top and bottom pieces of the busway housing. Optionally, epoxy is also applied between adjacent pairs of busbar conductors, which are stacked and arranged into the housing. Pressure is applied to the housing stack, and the epoxy is allowed to cure, resulting in a busway having superior thermal performance, dielectric integrity, and mechanical strength compared to conventional busways.

摘要： The present invention provides a method for installing circuit breakers of different frame sizes into an electrical distribution device at the at the factory or on the jobsite without having to remove the original factory installed line and load busing and installing new line and load busing for the particular frame size of the circuit breaker to be installed. The invention also provides a means for reducing the number of line and load busing assemblies that the electrical distribution device manufacturer must keep in inventory.

摘要： A scalable power tap off system is provided for a power distribution system. The system can have components including a line-side connector assembly for connecting to an upstream power supply, a load-side connector assembly for connecting to downstream load(s), and a draw-out circuit breaker assembly connected between the line-side and load-side connector assemblies. The system also includes a shutter assembly having a movable shutter for proving a barrier to prevent access to at least line-side electrical components on the breaker assembly when the breaker assembly is in the racked-out state, and insulated interconnect buses for electrically connecting the line-side connector assembly and the load-side connector assembly to the breaker assembly. An enclosed compartment is provided to house the load-side connector assembly in isolation from other components and allows access to the load-side connector assembly when the breaker assembly is in a racked-out state or the load-side connector assembly is de-energized.
