PGFI Series, Ground Fault Circuit Interrupter (GFCI)

Ground Fault Circuit Interrupters (GFCIs) are crucial devices used for circuit protection to prevent accidental electrocution. GFCIs continuously monitor the flow of electrical current in and out of an electrical load or circuit. They are designed to detect even small imbalances in current, as low as 5 milliamperes (mA). The main purpose of a GFCI is to rapidly disconnect the power supply to the load when it detects a difference in current flow. This quick disconnection helps prevent electric shocks and potential harm to individuals. Once triggered, the GFCI must be manually reset to restore power to the load. GFCIs can be installed in various ways depending on the specific application. They can be integrated into existing circuits by using in-line splicing techniques. Alternatively, they can be mounted directly onto outlet boxes as separate modules or incorporated into cord end plugs, enabling portable protection. For larger electrical systems, panel-mounted sensing modules are available, providing GFCI protection for multiple outlets or circuits. By incorporating GFCIs into electrical systems, the risk of electric shock and electrical accidents is significantly reduced. They are commonly used in areas where water is present, such as bathrooms, kitchens, outdoor outlets, and construction sites. GFCIs are a critical safety measure that ensures the well-being of individuals and provides peace of mind when using electrical devices.
