Abstract

Abstract This invention relates to a panelboard assembly which is largely composed of a number of standard premanufactured components. The components may be easily assembled together to give a variety of combinations of assemblies so as to be adaptable to receive an exceedingly large number of breaker combinations. Because most of the interior components of the panelboard are fabricated from standard extrudable components, it is possible to manufacture the panelboard in a variety of lengths and widths, so as to be able to supply panelboards having a wide range of power ratings. Also, because of the case with which the interior components of the panelboard may be conveniently manufactured in various dimensions, it is possible to adapt the panelboard for use in areas where physical dimensions are limited because of some prior requirement, such as a restraint on size due to the installation of a previously smaller-rated panelboard or some other restriction of a similar nature.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 149 words
A panelboard assembly comprising an enclosure, a pair of elongated side supporting members supported in said enclosure in a generally parallel spaced relationship, each of said siDe supporting members having a constant cross section along the entire length thereof with an elongated slot along the entire length thereof open at the front thereof, a plurality of fastening devices captured in said slots, a pair of cross supporting members, screw means connected to said fastening devices to support said cross supporting members on said side supporting members in a generally parallel spaced relationship across said side supporting members, each of said cross supporting members comprising a separate insulating bus bar support means, and a plurality of elongated bus bars supported on said insulating bus bar support means in between said side supporting members in a spaced relationship generally parallel to each other and generally parallel to said side supporting members.
Claim 2
Dependent Claim 149 words
A panelboard assembly comprising an enclosure, a pair of elongated side supporting members supported in said enclosure in a generally parallel spaced relationship, each of said siDe supporting members having a constant cross section along the entire length thereof with an elongated slot along the entire length thereof open at the front thereof, a plurality of fastening devices captured in said slots, a pair of cross supporting members, screw means connected to said fastening devices to support said cross supporting members on said side supporting members in a generally parallel spaced relationship across said side supporting members, each of said cross supporting members comprising a separate insulating bus bar support means, and a plurality of elongated bus bars supported on said insulating bus bar support means in between said side supporting members in a spaced relationship generally parallel to each other and generally parallel to said side supporting members.
Claim 3
Dependent Claim 79 words
A panelboard assembly according to claim 1, each of said side supporting members having another elongated slot along the entire length thereof open at the outer side thereof, a plurality of other fastening devices captured in said other slots, said enclosure comprising a base, a plurality of support members supported on said base, and other screw means cooperating with said support members and connected to said other fastening devices to support said side supporting members on said support members.
Claim 4
Dependent Claim 18 words
