The present invention is directed to an electrical wiring inspection system. The system includes an electrical measurement apparatus having at least one load center connector configured to couple the electrical measurement apparatus to a load center, at least one branch circuit connective device configured to couple the electrical measurement apparatus to a portion of a branch circuit, and at least one electrical measurement circuit disposed between the at least one load center connector and the at least one branch circuit connective device. The at least one electrical measurement circuit is configured to perform a series of electrical test procedures to obtain a plurality of electrical parameters. A portable computing device (PCD) includes processing circuitry, a user interface coupled to the processing circuitry, and at least one communications interface configured to couple the portable computing device to the electrical measurement apparatus. The processing circuitry is configured to direct the at least one electrical measurement circuit via the at least one communications interface to perform the series of electrical test procedures in response to an input from the user interface.
