Abstract: 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.

Abstract: A device includes test transmitter having a hot test prong configured for electrical coupling the test transmitter with a hot line of an electrical circuit and signal generator, coupled to the hot test prong, configured to generate a ping signal on the hot line. The hot test prong is configured for insertion into a hot receptable of the electrical outlet. The ping signal is received over the hot line from a test transmitter coupled to the electrical circuit. The device includes a neutral receive prong configured for electrical coupling with a neutral line and a ground receive prong configured for electrical coupling with a ground line. The device may detect presence of the ping signal at the neutral receive prong when a reversed polarity wiring configuration exists and at the ground receive prong when a bootleg ground configuration exists.
