Abstract: A bus bar stab and insulator assembly for a motor controller has a two-piece housing and a three-piece stab finger clip. The housing base has a number of partitions which define pathways for the stab fingers. The housing cover is slidably mateable with the base and has a tab for receiving a self tapping screw. The stab fingers extend from the housing for making contact with bus bars. The stab finger clip has two fingers with interlocking tabs secured together with a screw which also connects one or more connector cables to the clip. The fingers are constructed of copper alloy and do not require the use of springs.

Abstract: A molded case circuit breaker has control terminals mounted on the front of the breaker and accessible from the front. A transparent plexiglass cover is positioned over the terminals to prevent inadvertent contact with the terminals and an opening is provided in the side of the casing for the egress of the control wires. With the control terminals on the front of the circuit breaker, an inspection can be performed without disconnecting power from the breaker.
