Electrical connectors with integral fault detection and indication

An electrical connector adapted to be coupled to an AC multi-phase electrical cable, the electrical connector comprising:

• a plurality of phase contacts, the plurality of phase contacts including a first phase contact, a second phase contact, and a third phase contact to receive a first phase, a second phase, and a third phase, respectively, of the AC multi-phase electrical cable;
• a ground contact, the ground contact to receive a ground of the AC multi-phase electrical cable;
• a detector configured to monitor for a phase-ground swap fault between any one of the first phase contact, second phase contact, or third phase contact, and the ground contact;
• an indicator device operatively coupled to the detector to signal presence of the phase-ground swap fault;
• and
• wherein the AC multi-phase electrical cable is a 4-wire AC multi-phase electrical cable including a first phase wire, a second phase wire, a third phase wire, and a ground wire, and wherein the detector comprises a resistance circuit electrically coupled to the first phase wire, the second phase wire, and the third phase wire, to generate a virtual neutral signal, the detector using the virtual neutral signal in monitoring for the phase-ground swap fault between any one of the first phase contact, the second phase contact, or the third phase contact, and the ground contact.
