摘要： This invention provides a device which facilitates electrical wiring and equipment costs for electricians installing disconnect boxes, typically in the vicinity of an outside air conditioner unit. Thus, an improved disconnect box for protection of an electrician who is servicing an electrical appliance such as an outside air conditioner is provided which incorporates an integrally mounted auxiliary electric socket accessory giving the electrician a source of power for use while the electrician is safely assured that there is no power connected to the electrical appliance being serviced. The auxiliary electrical socket accessory may optionally be connected to a power line source as a full time electric plug outlet or one only accessible when the disconnect box is conditioned to disconnect power from the electrical appliance. Provisions are made for protection of the electrical socket accessory with fusing or circuit breaker protection and ground fault protected electrical input wiring to the electrical socket. The disconnect box is preferably weatherproofed for outside use to serve as a common housing for waterproofing the electrical socket. By provision of the improved disconnect box, the electrician can more efficiently install an auxiliary access socket for use of the electrician when the electrical appliance is disconnected either in retrofit or initial installations.

摘要翻译： 本发明提供了一种便于电气布线和设备成本的装置，该装置通常在外部空调单元附近安装断开盒。 因此，提供了一种用于保护正在维修诸如外部空调器的电器的电工的改进的断开盒，其包括一体地安装的辅助电插座附件，其给予电工一个使用电源，同时电工被安全地保证 没有电力连接到正在维修的电器。 辅助电源插座附件可以可选地作为全时电插头插座连接到电源线源，或者仅当断开盒被调节以从电气设备断开电源时才能访问。 通过熔断或断路器保护和接地故障保护的电气输入接线对电源插座进行保护。 断开箱优选是防风雨的，用于外部使用以用作用于防水电插座的公共壳体。 通过提供改进的断开盒，当电气设备在改造或初始安装中断开时，电工可以更有效地安装用于电工的辅助通道插座。
