A GFCI receptacle is designed to trip at what current level?

A Ground Fault Circuit Interrupter (GFCI) receptacle is specifically designed to protect against electrical shock by tripping when it detects a difference in the electrical current between the hot and neutral wires. This difference usually indicates that electricity is leaking through a path, which could be through a person who is grounded.

The standard current level that a GFCI receptacle is set to trip is typically at 6 mA. This means that when the leakage current reaches this level, the GFCI will cut off power to prevent potential injury or fatality. This low trip level is essential for ensuring safety, as it can quickly respond to potentially hazardous conditions before they cause harm.

Understanding this aspect of GFCI receptacles is critical for anyone working in electrical trades, as it underscores the importance of properly using GFCI devices in environments where water or conductive materials are present, such as kitchens, bathrooms, and outdoor areas.
