Abstract
Abstract A plurality of flat, elongated bus bars are flatwise aligned in a stack and spaced to receive plug-on jaws of relatively large circuit breakers. For mounting relatively small circuit breakers not suitable for plugging directly onto the bus bars of the stack, a plug-on mounting device for the relatively small circuit breakers is provided and includes a plurality of terminal attachment buses each having a plug-on jaw member secured thereto and pluggable onto one of the bus bars of the stack. The terminal attachment buses extend perpendicularly to the bus bars of the stack when plugged thereon by their plug-on jaws and the lengthwise dimension of the relatively small circuit breakers, extending from line to load terminals thereof, is perpendicular to the bus bars of the stack when the relatively small circuit breakers are plugged on the terminal attachment buses by their plug-on line terminals.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
A mounting device for securing a small current capacity circuit breaker having at least one rear projecting plug-on jaw within a panelboard assembly of the type having a plurality of bus bars and having means for securing relatively larger current capacity circuit breakers with side projecting plug-on jaws in electrical contact with the bus bars, wherein the mounting device comprises a. a base; b. retaining means for mechanically retaining a small current capacity circuit breaker in removably fixed position with respect to said base; and c. a plurality of terminal buses secured to said base, each said terminal bus including 1. a plug-on conductive jaw for making electrical contact with one of the panelboard bus bars, and 2. jaw receiving means for making electrical contact with the plug-on jaw of a small current capacity circuit breaker, said jaw receiving means including an elongated conductive portion, said terminal bus plug-on jaws extending in a first plane and said elongated conductive portions extending in a second plane perpendicular to said first plane, each said elongated conductive portion being positioned with its longitudinal axis perpendicular to said first plane to make electrical and mechanical contact with the rear projecting plug-on jaw of a small current capcity circuit breaker.
