摘要： 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.

摘要： An electric busway system consists of a plurality of planar bus bars insulated from each other and bolted together for good mechanical strength and for efficient thermal conductivity. The bus bars are additionally perforated to promote convective air current flow through the perforations when the bus bars are mounted in the horizontal plane.

摘要： A molded plastic load center enclosure permits the circuit breakers contained therein to be compactly aligned on one side of the enclosure. The insulative properties of the plastic allows the circuit breaker branch straps to be mounted on the bottom and side walls of the enclosure. The end of the bottom-mounted branch strap is formed for direct connection with the line terminals. The end of the side-mounted branch strap is apertured for convenient connection with the line terminals. Metallic attachment caps are pressed within the bottom of the enclosure to facilitate mounting to a support post.

摘要： A three piece molded plastic enclosure for electric service entry apparatus such as meters, fuses, circuit breakers and switches. The enclosure provides protection against adverse environmental conditions while providing visual access to the components contained therein. The enclosure is tamperproof by virtue of a hinge arrangement formed between a stationary cover and a movable door. Once the door is assembled to the cover, the door cannot be easily removed without a separate tool.
摘要翻译： 电子服务输入设备如电表，保险丝，断路器和开关的三件式塑料外壳。 外壳提供防止不利环境条件的保护，同时提供对其中包含的组件的视觉访问。 通过在固定盖和可移动门之间形成的铰链装置，外壳是防篡改的。 一旦门组装到盖子上，门就不能轻易地拆下而没有单独的工具。

摘要： 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.
摘要翻译： 用于断开开关的三件式模制塑料外壳，由通过注射成型工艺单独制造的基座，盖子和门组成。 基座具有与门上的整体模制的搭扣配合的整体模制的延伸片，以允许外壳被挂锁。 两部分铰链，其中铰链的一部分与盖一体地形成，并且剩余部分与门一体地形成，允许门以铰链状的方式组装到盖上。 电气部件附接到基座的内部，并且基座通过螺钉固定到盖上。 当隔间解锁时，螺钉只能从门后方进入。 除了提供在锁门后面防篡改的断开开关，模制塑料外壳是防水和环境安全的。
