When the problem is in the electrical circuit leading to the receptacle, each splice or terminal point should be checked along the entire circuit for a break or loose connection. Before this test procedure is started, be sure the power to the suspected switch has been turned OFF.

Failure to secure power could result in a fatal electrical shock. More people are killed by normal household current than high voltage. When energized circuits are being worked on, the worker should be trained according to 29 CFR 1910.333 and use the protective equipment specified in 29 CFR 1910.335.
Remove the faceplate from the switch and unscrew the switch from the junction box. Pull the switch away from the metal box and position it so that no bare wires can touch the box. When the switch is in a SAFE position, power may be restored and the test procedure started.
In remodeling you may find it necessary to check which wires provide power to the circuit and which wires merely continue on to feed other circuits. The neon tester can simplify this procedure by individuallyContinue Reading
