GFCI , or Ground Fault Circuit Interrupter, outlets are required by code on outdoor outlets, or any outlet near a source of water. The one exception is that outlets intended for motor-driven appliances, like washers and driers, don't need a GFCI, as GFCIs don't work with inductive loads.
They work well when new, but eventually fail and need to be replaced. Here's how to replace a GFCI outlet- or any outlet, really- or replace a standard outlet with a GFCI outlet.
Step 1: What you'll need
It doesn't take many tools to do this job- here's what you'll need:
- New GFCI outlet
- Insulated screwdriver
- Outlet tester
- Non-contact tester
- Electrician's pliers
All are inexpensive. The non-contact tester is used to see if a circuit is "hot"- that is, if there's voltage on it. The Outlet tester is used to make sure you've wired everything properly.
