November 4, 2024
Ground-fault circuit interrupters (GFCIs) are safety devices that monitor the flow of electrical current, shutting off power quickly when electricity flows through the wrong pathway. This is known as a ground fault or tripping circuit, which can result in an electrical fire or even shock.
What is a GFCI Extension Cord & How do I Stop It Tripping?
These are simply extension cords with inbuilt GFCI receptacles, often used in outdoor settings to prevent equipment damage and keep users safe. Understanding why these devices trip helps ensure they’re used more effectively.
Common tripping causes include:
Ground fault: Detecting electrical current as it flows through a human body, water, or other unintended pathway causes the device to trip as designed. Generally, ground faults occur when devices are damaged or wet in places where moisture shouldn’t be.
Solution: Switch off and unplug electrical devices connected to the circuit, checking for wear, damage, or other issue that may have caused it. If a repair is necessary, it’s best to call an electrician.
Overload: When too much amperage flows through wiring or circuitry, overloads occur, leading to tripping. Defective or malfunctioning devices and loose electrical connections often cause this.
Solution: Unplug all devices connected to the tripping circuit, plugging each device individually to identify which is causing the overload; sometimes, the offending device must be plugged into a dedicated circuit to prevent tripping.
Moisture: Tripping commonly occurs when rain gets into GFCI receptacles, though humidity or spills can also cause water to get where it shouldn’t be.
Solution: Wait for the box containing the receptacle to dry before resetting the GFCI; to help prevent this issue altogether, ensure this box is weatherproof and locked.
Electrical fault: This occurs due to faulty structural wiring, normally identifiable by an overly warm outlet cover or burning plastic smell.
Solution: Contact a certified electrician to conduct an assessment and repair.
Debris: Dust and other debris can disrupt electrical flow, which can then cause overheating that leads to an electrical fire.
Solution: Use a brush with soft bristles to remove debris.
Faulty GFCI: If all other causes have been eliminated as the source of the GFCI extension cord tripping, it’s most likely a problem with the GFCI itself. As with any electrical device, circuitry wears out over time and eventually fails. If the device malfunctions and trips frequently, this is likely the problem. Typically, GFCI receptacles last about 15 to 25 years, though defective ones may fail after just a few years.
Solution: Contact an electrician to repair or replace the GFCI device or even purchase a new GFCI extension cord.
