A method for power source identification of one or more wireless testing devices connected to one or more electric circuits of a breaker panel, wherein the one or more wireless testing devices are configured to generate and transmit one or more service set identifier (SSID) communication signals to a receiver device simultaneously, based on input of corresponding electric circuit, and wherein the receiver device is configured to provide a user interface for power source identification of the breaker panel, the method comprising:
- plugging one or more wireless testing devices into power receptacle outlets of one or more electrical circuits;
- turning off each electric circuit one by one;
- monitoring and recording the wireless testing devices connected to each electric circuit, based on corresponding SSID signals received, after said corresponding electric circuit is turned off one by one;
- and
- displaying electrical circuits associated with each wireless testing device on the user interface.
