A prefabricated electrical module and system along with fabrication and installation methods are provided. The prefab electrical module includes a circuit breaker panel casing that houses multiple circuit breakers, and a chase extending upwardly from the panel casing that stows coiled lengths of homerun wiring attached to the circuit breakers. During transport, a temporary panel casing front cover protects the panel casing front, and a forwardly protruding guard cover with an upwardly projecting hoisting handle shields the front and top of the chase and wiring. During installation, a hoisting bracket is attached at the top of the stud bay into which the prefab electrical module will be installed. A drill-powered winch is then used to lift the module to the proper height in the bay. The panel casing, chase, wiring, and breakers remain in the wall. The hoisting bracket, temporary panel casing front cover, guard cover, drill, and winch are reusable.

The power distribution system includes a plug-in frame, a board located in the plug-in frame, and at least one circuit breaker. The board includes a plurality of slot positions, a position signal acquisition apparatus is disposed on the board, and the position signal acquisition apparatus is configured to acquire an address of any slot position on the board. A first end of each circuit breaker extends into the plug-in frame and is plugged to a slot position on the board, and a second end of the circuit breaker is located at an open end of the plug-in frame. The open end of the plug-in frame is provided with an address code, the address code corresponds to an address of a slot position on the board, and each circuit breaker corresponds to at least one address code.

A line terminal is for an electrical switching apparatus. The electrical switching apparatus includes a stationary contact and a movable contact structured to move into and out of engagement with the stationary contact in order to close and open the electrical switching apparatus, respectively. The line terminal includes a lip portion structured to be connected to the stationary contact in order to provide an electrical pathway therebetween; an arm portion extending from the lip portion, the arm portion having an engaging portion structured to receive and engage a conductive post member and provide an electrical pathway between the conductive post member and the stationary contact; a neck portion extending from the arm portion; and a tab portion extending from the neck portion and being located internal with respect to the engaging portion.
