1Testing outlets for power
- 1.1Turn off power to any outlets and switches at the service panel. Confirm that the panel is off with a voltage tester.
- 1.2Insert the probes of a voltage tester into the outlets. If the tester light glows, the power is still on.
- 1.3Unscrew and remove the outlet cover plates. Touch the tester probes to the terminal screws at the ends of the black and white wires, then the black wire and the green ground wire to make sure that it is turned off.
