US Patent:

48048046, Feb 14, 1989
Filed:

Nov 19, 1987
Appl. No.:

7/122863
Inventors:

David A. Hibbert - South Windsor CT
Anthony L. Richards - Southington CT
Dennis C. Zuffelato - Kensington CT
Conrad R. Turmelle - Farmington CT
Harold F. Larkin - Plainville CT
Assignee:

General Electric Company - New York NY
International Classification:

H02G 506
H02G 510
US Classification:

174 162
Abstract:

A two-piece extruded aluminum alloy housing is shaped to provide support and ground conduction facility to power busway conductors contained therein. The two-piece housing is attached together with snap-fit connectors along its top and bottom surfaces. The housing is attached to the busway power conductors by means of insulated bolts. The bolts may be hollow so that air can flow through the bolts to aid in cooling the conductors within the housing by convection.

US Patent:

48495816, Jul 18, 1989
Filed:

May 16, 1988
Appl. No.:

7/194655
Inventors:

Harold F. Larkin - Plainville CT
David A. Hibbert - South Windsor CT
Julie A. Beberman - New Hartford CT
Clarence W. Walker - Selmer TN
Assignee:

General Electric Company - New York NY
International Classification:

H01R 1320
H02G 1508
US Classification:

174 88B
Abstract:

The outer surfaces of adjoining electrical busway side frames are shaped to define a protruding rail extending along the vertical axis thereof. A pair of recessed channels formed within the inner surfaces of the side frames of an intervening busway joint receive the busway rails at opposing ends thereof. Clearance arranged within the respective busway joint channels allows lateral movement of the busway side frames relative to the busway joint. Slots are provided on the busway joint side frames for visual indication of the position of the busway rails.

US Patent:

48425338, Jun 27, 1989
Filed:

May 12, 1988
Appl. No.:

7/193000
Inventors:

Julie A. Beberman - New Hartford CT
Ira B. Goldman - Waterbury CT
Harold F. Larkin - Plainville CT
David A. Hibbert - South Windsor CT
Assignee:

General Electric Company - New York NY
International Classification:

H01R 1360
US Classification:

439213
Abstract:

A thermally efficient joint for electrical power distribution busway electrically connects between adjacent busway sections. Each busway joint includes a modular assembly containing spaced metallic splice plates separated by corresponding insulating plates. The module is sandwiched between a pair of joint covers by means of an insulated thru-bolt. The spacing between the splice joint for receiving corresponding busway stabs is accurately set by an apertured depression stamped within each of the splice plates.

US Patent:

50270958, Jun 25, 1991
Filed:

Oct 29, 1990
Appl. No.:

7/604284
Inventors:

Geoffrey H. McKay - West Hartford CT
Harold F. Larkin - Plainville CT
Dennis J. Doughty - Plainville CT
Michael C. Guerrette - Plymouth CT
Assignee:

General Electric Company - New York NY
International Classification:

H01H 902
US Classification:

335202
Abstract:

A molded case circuit breaker of the type using electrodynamic repulsion to separate the circuit breaker contacts under intense overcurrent conditions also includes an arc chute arrangement for cooling and quenching the arc that occurs during such contact separation. A plastic cover insert added to the interior of the circuit breaker cover multi-functionally retains the arc chute within the circuit breaker case while providing clearance for the circuit breaker operating handle shutter. A resilient pad on the top surface of the cover insert receives the circuit breaker operating handle skirt upon contact separation and dampens the energy imparted to the operating handle and to the circuit breaker cover.
