Abstract: A device is provided for inspecting an installed electrical system including a power panel and branch circuits with respective circuit breakers. The device includes a power interface unit with a Ground Fault Circuit Interrupter (GFCI) for connection with the power panel. Further, the device includes a power source for temporarily powering the electrical system through the GFCI. For safety purposes, the device allows the energized GFCI to be closed only when the device and the power panel are connected. Moreover, the device provides for selective closing of the circuit breaker of an individual branch circuit to test a power response thereof to indicate whether the individual branch circuit has a fault therein.

Abstract: A device and method for easily and safely providing temporary electric power to buildings to permit inspection of electrical circuits. The device is a power connector configured to safely and easily provide temporary power to a building unit through receptacles of a standard power meter socket. The connector has at least two spades, a GFCI circuit breaker with a male plug designed to connect the connector to a temporary power source at the electric potential needed for the building. For a typical residence in the United States, this would be a four-prong 120/240 volts ac plug. In preferred embodiments the power connector has the approximate shape of the back side of a standard power meter and the male plug is at the end of a short 120/240 four wire electric power cable. This preferred embodiment also includes three toner posts (two “hot” posts and one neutral post on the load side of the GFCI breaker) for application of a tone from a toner device.
