Ground Verification

The capabilities of grounding and wiring verification devices include:

  • Detecting isolated ground shorts and neutral-ground bonds
  • Ground impedance and neutral impedance measurement or indication
  • Detecting open grounds, open neutrals, and open hot wires
  • Detecting hot/neutral reversals or neutral/ground reversals

Three-phase wiring testers should also test for phase rotation, and phase-to-phase voltages.
