Patent ID: 7227282

Claim:
A method of providing a backup power supply with a temporary power connector having a cord with at least two electrically insulated conductors therein, a first end and an opposing second end, a first male plug on the first end, and a second male plug on the second end, said method comprising the steps of: a) opening at least one main breaker in an integral electrical distribution system of one of a vehicle and a building, said electrical distribution system having a plurality of nodes and normally powered by an alternating power source configured to provide alternating current from the alternating power source out of the plurality of nodes at outlets, wherein the alternating power source is temporarily electrically isolated from being in electrical communication with a first outlet with the opening of the at least one main breaker; b) plugging the first male plug into the first outlet of the plurality of outlets of the electrical distribution system downstream of the opened at least one breaker; and c) plugging the second male plug into a second outlet of a backup power source, said alternative power source providing alternating current to a selected portion of the electrical distribution system downstream of the at least one main breaker through the first and second outlets; whereby the alternative power source provides the alternating current into the first outlet in an opposite direction of current flow than the first outlet has with the alternating power source normally powering the electrical distribution system when an appliance is connected to the first outlet.
