Do the following to test a two-slot receptacle: Place one probe in the hot slot and the other end on the screw securing the cover plate. The screw must be clean as well as paint and grease free.
- If the receptacle is grounded, the tester’s bulb will light up.
- Put the probe in the neutral slot if the tester does not light up in the hot slot. If it lights, the receptacle is grounded, but the neutral and hot wires have been reversed and are attached to the wrong terminals. If the bulb doesn’t glow at all, the receptacle isn’t grounded.
- To be absolutely sure that the receptacle is grounded (if your test indicates that it is), turn the power off and remove the cover plate. Check to see if an actual grounding conductor is present.
