Devices, systems and methods for detecting reversed polarity bootleg ground wiring configurations of an electrical outlet are disclosed. For at least one embodiment, a system in includes a test transmitter and a test receiver. The test receiver being configured to detect a ping generated by the test transmitter and determine whether the ping is received via a proper receptacle of an outlet being tested. The system also includes a test receiver configured to determine is a bootleg ground configuration exists using one of time domain reflectometry and/or a resistance based measurement approach. A method for testing an outlet includes one or both of testing for reversed polarity and bootleg ground configurations.
