Test each shock-protection outlet with its Test button
Ground-fault circuit interrupters, usually called GFCIs, are the outlets or breakers with Test and Reset controls that can cut power during a dangerous current leak.
When it usually needs attention
Usually repeats every 1 month
The CPSC home electrical checklist says to test GFCIs monthly.
When this guide applies
Most U.S. homes have GFCI protection, but the device locations and protected outlets must be identified.
What to do
Map each accessible GFCI, follow the device label, press Test, confirm protected power turns off, then press Reset and record any failure.
Applies when: Most U.S. homes have GFCI protection, but the device locations and protected outlets must be identified.
Who should handle it: A resident may use labeled Test and Reset controls; electrical diagnosis, replacement, panel access, and shared-building work belong to the responsible owner and qualified electrician.
Tools
- Small plug-in lamp only if the device label or manual uses a load check
Parts and supplies
- No replacement parts for the user test
Safety gear
- Dry hands and dry floor; no special PPE makes wet or damaged electrical equipment safe
Before you start
- Identify equipment that must not lose power
- Read the device's Test and Reset labels
Power, water, or fuel shutoffs
- Do not remove a cover or open the electrical panel for this user test
Cleaner or chemical limits
Use no liquid cleaner, spray, lubricant, or compressed air on an outlet or breaker.
Stop and get help when
- Stop for heat, sparks, buzzing, smoke, discoloration, damage, moisture, a missing cover, or a device that will not test or reset
- Do not repeatedly reset a tripping device
Who to call: Keep the affected outlet or circuit out of use and use a qualified electrician or responsible property manager.
