How to Find an Open Ground in a House Circuit
- 1). Locate all the electrical outlets in the home.
- 2). Unplug any appliances from the outlet that will be tested.
- 3). Insert the tester into the outlet. Be sure the tester is fully seated in the receptacle.
- 4). Check the three indicator lights on the tester to determine the condition of the circuit. If the middle is illuminated and the two on either end are not, this indicates that an open ground exists.
