Electrical Plug Tester
Most electrical plug testers are relatively
inexpensive and usually under $20. They are extremely simple to use and
as the one shown in the picture above, on the top of it you will see a
diagram explaining what electrical outlet problems you might have
when certain lights on the tester appear.
Most home inspectors will carry this tool in their tool bags for easy access.
I recommend as a homeowner purchasing an electrical plug tester as a once in a lifetime purchase. You will be able to use this on any house to test the electrical outlets to make sure it is working perfectly.
An electrical plug tester only test electrical plug outlets and will not he able to tell you if other areas of the electrical system are not working properly.
The job of the electrical plug tester is to make sure the hot wire, neutral wire and grounding wires are hooked up to the proper side of the outlet.
