Do you have outlets (standard or GFCI) that you need to test? This video will show you how to test your outlets with a Standard and GFCI Outlet Tester. The tester we used is very inexpensive and can be purchased in most places that sell hardware. This is an Amazon link to a GFCI Tester. If you purchase a tester be sure it will test standard and GFCI outlets.
Here are 2 testers I have. The yellow one works well but is old and will not test a GFCI Outlet. The newer orange one will test both types of outlets.
In the video, Standard and GFCI Outlet Tester, I demonstrate using both on standard, GFCI Outlets and standard outlets that are protected by a GFCI Breaker that is at another location. If you have a outlet that looks like a standard outlet but you think it should be protected, this tester can confirm if it is protected or not.
