US Classification:

361356

Abstract:

A three-piece molded plastic enclosure for disconnect switches consisting of a base, cover, and door individually fabricated by means of an injection molding process. The base has integrally molded extension tabs cooperating with an integrally molded hasp on the door for allowing the enclosure to be padlocked. A two-part hinge wherein part of the hinge is integrally formed with the cover and the remaining part is integrally formed with the door allowing the door to be assembled to the cover in a hinge-like fashion. Electrical components are attached to the interior of the base and the base is secured to the cover by means of a screw. The screw is only accessible from behind the door when the compartment is unlocked. Besides providing a disconnect switch that is tamper-proof behind a locked door, the molded plastic enclosure is water-tight and environmentally secure.

Appl. No.:

7/026496

Inventors:

David A. Hibbert - South Windsor CT
Larry J. Newmark - Avon CT

Assignee:

General Electric Company - New York NY

International Classification:

H01H 900
H02B 100

US Classification:

361331

Abstract:

A fused disconnect switch is contained within a molded plastic cover pivotally attached to a molded plastic case. The switch contact blade is directly attached to the cover whereby movement of the cover in one direction slidingly connects the switch contact blade between the line and load stabs mounted within the case. Movement of the cover in an opposite direction slidingly disconnects the switch contact blade from the line and load stabs. Elongated slots integrally formed within the cover and the case cooperate to prevent access to the switch components when the switch blade is in its "ON" position. The configuration of the slots allow for locking the switch in either the "ON" or "OFF" position.

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.
