What is a GFCI and how does it work?
A Ground Fault Circuit Interrupter (GFCI) is a device designed to protect people from electric shock by monitoring the flow of electricity in a circuit. When it detects an imbalance in the electrical current — indicating a ground fault — it quickly cuts off the electricity, reducing the risk of severe injury or death. GFCIs are commonly found in areas where electricity and water might come into contact, such as kitchens, bathrooms, and outdoor spaces.
GFCIs can be installed as standalone outlets or as circuit breakers within the electrical panel. They continually monitor the current and can respond in less than a second to ground faults, ensuring both safety and compliance with electrical codes. Understanding how they function is crucial for recognizing when they are not working properly.
What causes a GFCI to stop working?
There are several common reasons why a GFCI may stop working. One of the most prevalent causes is a tripped circuit, which can occur due to an overload, moisture, or a malfunction in the connected appliances. Other causes include a faulty wiring connection, defective components within the GFCI itself, or wear and tear over time that leads to degradation of the device.
Additionally, external factors such as exposure to extreme temperatures and humidity can impact the performance of a GFCI. If the wiring leading to the GFCI is damaged, it may also result in the device failing to operate correctly. Diagnosing the exact cause is essential for effective resolution.
