    Study Notes

    Ground Fault Circuit Interrupter (GFCI) Overview

    • GFCI is an electrical safety device that de-energizes a circuit when a ground fault is detected.
    • Designed for both person and property safety in accordance with National Electrical Code (NEC).
    • Commonly used in wet locations to prevent electrical hazards.

    Purpose and Function of GFCI

    • Protects people and pets from severe electrical shocks, which could be lethal.
    • Monitors the electrical current flowing in a circuit to detect any imbalances, indicating a ground fault.
    • Instantly interrupts the electrical supply within milliseconds of detecting fluctuations to ensure safety.

    Types of Ground Fault Circuit Interrupters

    • Three main types of GFCIs found in residential settings:
      • GFCI Outlet
      • GFI Circuit Breaker
      • Portable GFCI
    • Each type serves the same safety function but varies in application and limitations.

    Receptacle-Type GFCI

    • Replaces standard convenience outlets and is commonly installed in areas prone to moisture, such as bathrooms, kitchens, and outdoor spaces.
    • Can be mounted into a standard electrical outlet box and is connected to the branch circuit.
    • Essential for enhancing safety in high-risk locations around the home.
