A method, apparatus and program product are provided for mapping electrical circuits. A user provides an electronic record of one or more rooms with outlets to be mapped and installs a module in each outlet to be mapped. Using an interactive program, the user prepares a diagram of a circuit box. The user triggers a probe to propagate a signal detectable by said modules over a circuit and to provide circuit information. The user retrieves the circuit information from the modules. Then, the interactive program associates the circuit information from each module with a corresponding outlet on said electronic record of one or more rooms.
