GFCI Outlet: How it works and how to test.

You’re supposed to test them once a month, but who does? Now’s a great time. You’ll find them around potentially wet areas — building codes specify GFCI outlets in bathrooms, kitchens, and for outdoor receptacles. Make sure the device trips and resets correctly. If you find a faulty outlet, replace it or get an electrician to do it for $75 to $100.
