Abstract

Abstract A circuit breaker includes a recessed zone in the breaker housing for accommodating the bus clip of a mating circuit breaker when the breakers are mounted adjacent one to another on a panelboard. An arcuate groove of varying depths formed in the breaker housing communicates at its lower end with the recessed zone to permit the bus clip of the mating breaker to be moved from the recessed zone and along the arcuate groove, such that the mating breaker can be readily removed from, or installed into, the panelboard.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 216 words
A pair of mating circuit breakers for installation in a panelboard, each of said circuit breakers comprising a housing, a bus clip mounted within said housing for attachment to a bus blade and having a portion extending outwardly therefrom, a recessed zone formed in a lower corner of one side of each of said housings adjacent said bus clip said recessed zone in one circuit breaker being provided for accommodating said bus clip of said other mating circuit breaker when said pair of breakers are mounted alongside one another on a panelboard, and a groove formed in said one side of the said housing of each of said circuit breakers and having a lower portion leading to each said recessed zone and in substantial alignment with the portion of each said recessed zone that is adapted to accommodate said bus clip of the other of said mating breakers when both of said circuit breakers are mounted adjacent one another on the panel board, each said groove being effective to receive and to permit said bus clip of the other of said mating breakers to pass directly between said recessed zone and said groove when one of said mating circuit breakers is pivoted relative to the other circuit breaker when the latter is mounted on the panelboard.
Claim 2
Dependent Claim 216 words
A pair of mating circuit breakers for installation in a panelboard, each of said circuit breakers comprising a housing, a bus clip mounted within said housing for attachment to a bus blade and having a portion extending outwardly therefrom, a recessed zone formed in a lower corner of one side of each of said housings adjacent said bus clip said recessed zone in one circuit breaker being provided for accommodating said bus clip of said other mating circuit breaker when said pair of breakers are mounted alongside one another on a panelboard, and a groove formed in said one side of the said housing of each of said circuit breakers and having a lower portion leading to each said recessed zone and in substantial alignment with the portion of each said recessed zone that is adapted to accommodate said bus clip of the other of said mating breakers when both of said circuit breakers are mounted adjacent one another on the panel board, each said groove being effective to receive and to permit said bus clip of the other of said mating breakers to pass directly between said recessed zone and said groove when one of said mating circuit breakers is pivoted relative to the other circuit breaker when the latter is mounted on the panelboard.
Claim 3
Dependent Claim 54 words
The circuit breaker arrangement of claim 1, in which each said groove includes a first part opening to each said recessed zone and of substantially the same depth as said recessed zone, and a second part angularly offset from said first part and having a variable depth less than that of said first part.
Claim 4
Dependent Claim 66 words
The circuit breaker arrangement of claim 1, in which each said groove comprises a first part leading to each said recessed zone and at substantially the same depth as said recessed zone, a second part angularly offset from said first part and at a lesser depth than said first part, and a third part of varying depth intermediate and leading to said first and second parts.
Claim 5
Dependent Claim 41 words
The circuit arrangement of claims 1, 2 or 3, further comprising a second groove in each breaker housing leading to each said recessed zone and spaced from said first-mentioned groove for accommodating a rejection tab secured to the each circuit breaker.
Claim 6
Dependent Claim 65 words
The circuit breaker arrangement of claim 1, in which said bus clips of said pair of breakers are spaced inwardly at different distances within said respective housings so that said bus clips of said breakers are respectively accommodated within said recessed zones of the other of said breakers and are in a side-by-side relationship when said breakers are mounted adjacent one another on the panelboard.
