You’ll know your house is properly grounded if every outlet tests positive for ground on a circuit tester, there’s a visible grounding electrode (rod, water pipe, or Ufer) connected to your panel, the panel has a properly sized grounding electrode conductor, and there are no two-prong (ungrounded) outlets in living spaces. A licensed electrician’s inspection confirms with measurements.
Signs of proper grounding
- All outlets test ground-positive on a tester
- Visible grounding electrode at panel
- No two-prong outlets in modern living spaces
- Resistance to ground under 25 ohms (electrician test)
- Properly sized grounding electrode conductor
