Abstract: 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.

Abstract: One embodiment permits retrofitting one or more laterally extending electrical boxes for extra switches, outlets or accessories such as rheostatic controls in existing walls without tearing out a portion of the wall, removing the box, rewiring a new ganged box and refinishing the wall. This invention provides modular lateral box extensions constructed to be installed from the open front end and supported by the installed box anchored to a beam with the wall being cut only enough to receive the extension modular box. This efficiently requires the wiring of only additional modules and avoids repair and repainting of walls.
