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。

摘要： 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.
摘要翻译： 熔接断开开关包含在可塑连接到模制塑料外壳上的模制塑料盖中。 开关接触片直接连接到盖子上，因此盖子沿一个方向的移动将开关接触片滑动地连接在安装在壳体内的线路和负载插头之间。 盖子在相反方向上的移动可以将开关接触片与线路滑动地断开并加载刺针。 一体地形成在盖和壳体内的细长槽协作以防止当开关刀片处于“开”位置时进入开关部件。 插槽的配置允许将开关锁定在“ON”或“OFF”位置。

摘要： A molded plastic load center enclosure allows 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 load terminals.

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： Molded plastic outlet boxes are attached to an electric busway power distribution system at each location along the system where the bus bar conductors are provided with plug-in stabs. Slotted openings arranged through a top of the outlet box are centered with respect to the busway stabs to assist in connection therewith. A molded plastic access cover can be mounted optionally on either side of the box to electrically isolate the busway stabs.

摘要： 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.
