Ground-Fault Circuit Interrupters (GFCIs) are essential safety devices designed to protect you from electrical shock and reduce the risk of fire. If your GFCI outlet keeps tripping, it’s not just an inconvenience it’s a warning sign that something isn’t right in your electrical system. At Lights On Electric, we want to help you understand why this happens and when it’s time to call a professional.
Here are the five most common reasons your GFCI outlet may be tripping:
1. Ground-Fault Occurrence
This is the most common cause of a GFCI trip. A ground fault happens when the “hot” (live) wire touches the ground wire or a grounded part of a device. GFCI outlets are incredibly sensitive and will shut off power immediately if they detect even a tiny amount of current (as low as 0.005 amps) flowing where it shouldn’t such as through water or a person.
What to do:
Unplug all devices on the circuit and turn off any switches. Look for any visible damage to cords or outlets. If you suspect a ground fault but can’t locate the source, it’s best to have a licensed electrician inspect it.
2. Moisture in the Receptacle Box
Operating out of Philadelphia, we frequently see moisture as a major reason GFCI outlets trip especially in outdoor outlets or damp areas like kitchens and bathrooms. Condensation can sometimes form inside the outlet box, increasing the risk of electrical issues.
What to do:
Turn off the breaker and check the receptacle box for any signs of water. The box must be completely dry before resetting the outlet. If you’re unsure, avoid using a hairdryer or tools near electrical components and call a professional instead. For outdoor or damp area outlets, always use weatherproof, sealed covers.
3. Overloaded Circuit
Too many devices on one circuit can draw more power than it can handle, causing the GFCI to trip to prevent overheating or fire. This often happens with high-wattage appliances or overuse of power strips.
What to do:
Unplug everything on the circuit. Reset the breaker and plug in one device at a time, checking if the circuit trips again. If one appliance is the problem, it may need repair or replacement. In some cases, you may need a dedicated circuit for high-powered equipment.
4. Electrical Fault
If your GFCI keeps tripping with no obvious cause, it could point to a more serious electrical issue such as damaged wiring, loose connections, or a fault in another outlet or fixture on the same circuit. These hidden problems can pose fire and shock risks if left unaddressed.
What to do:
This is not a DIY situation. Call a licensed electrician to inspect the circuit, check for damaged wires, loose terminals, or faulty devices, and identify any underlying issues. A professional diagnosis is essential to ensure your system is safe, up to code, and operating correctly.
5. Faulty GFCI Outlet
Like any device, GFCI outlets can wear out over time. Their internal sensors, contacts, or circuitry may fail, leading to false trips or preventing the outlet from resetting properly. Age, frequent use, moisture, or power surges can all shorten the lifespan of a GFCI.
What to do:
If you’ve ruled out other causes like overloads, moisture, or wiring issues the outlet itself may be the problem. In this case, the GFCI should be replaced. Always have a certified electrician handle the replacement.
