Abstract
Abstract A panelboard is constructed with a line terminal array in a row midway between mechanical parallel elongated support means for the circuit breaker load ends. Disposed outboard of and extending parallel to each support means is an elongated neutral bar having a plurality of load wire grips thereon. Main lugs for energizing the line terminal array are disposed at one end thereof, and at the other end thereof a connecting bar extends between the neutral bars for an electrical interconnection therebetween.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
An electrical power distribution device including a base, first and second parallel elongated neutral bars mounted to said base, first and second elongated mounting formations on said base for supporting load ends of circuit breakers when the latter are mounted to said device, said first and second mounting formations being in the vicinity of the respective first and second neutral bars and being positioned inboard thereof, a line contact array disposed between said mounting formations to be electrically engaged with circuit breakers when the latter are mounted to said device, an electrical conductor disposed at one end of said array and having its opposite ends secured to said first and second neutral bars to provide an electrical connection therebetween.
Claim 2
Dependent Claim
119 words
An electrical power distribution device including a base, first and second parallel elongated neutral bars mounted to said base, first and second elongated mounting formations on said base for supporting load ends of circuit breakers when the latter are mounted to said device, said first and second mounting formations being in the vicinity of the respective first and second neutral bars and being positioned inboard thereof, a line contact array disposed between said mounting formations to be electrically engaged with circuit breakers when the latter are mounted to said device, an electrical conductor disposed at one end of said array and having its opposite ends secured to said first and second neutral bars to provide an electrical connection therebetween.
Claim 3
Dependent Claim
24 words
An electrical power distribution device as set forth in claim 1 also including main lugs connected to the array at the other end thereof.
Claim 4
Dependent Claim
74 words
An electrical power distribution device as set forth in claim 1 in which holding formations on the base position the neutral bars transverse to their longitudinal axes; a connecting bar constituting said electrical conductor said mounting formations having apertures through which the connecting bar extends; said apertures being disposed and proportioned to block movement of the connecting bar parallel to said axes to thereby prevent movement of said neutral bars parallel to said axes.
Claim 5
Dependent Claim
24 words
An electrical power distribution device as set forth in claim 3 also including main lugs connected to the array at the other end thereof.
Claim 6
Dependent Claim
35 words
An electrical power distribution device as set forth in claim 3 in which the neutral bars include complementary formations which interlock with the holding formations for sliding engagement of the latter with the neutral bars.
Claim 7
Dependent Claim
24 words
An electrical power distribution device as set forth in claim 3 also including main lugs connected to the array at the other end thereof.
