Possible Causes for an Outlet Circuit not to Function
How to Repair a Faulty Outlet Circuit: An Outlet Circuit that Tests OK but still Does Not Work, Here are some reasons why an outlet may not work properly and what should be checked.
Electric Outlet Circuit Problem
- I have three outlets on a circuit. With my tester I get a reading of 120volt to ground and also between my hot and neutral.
- Nothing between ground and neutral of course. When I plug in my outlet tester, the test lights indicate that everything is working properly.
- When I plug in a nightlight or appliance, it doesn’t work, the same nightlight and appliance function properly in an outlet on another circuit.
- What could be the cause of a seemingly functioning outlet to not function when there is a load applied?
