In which situation is a GFCI required?

A GFCI, or Ground Fault Circuit Interrupter, is required when electrical equipment is used near water because it is designed to protect people from electrical shock. Water is a conductor of electricity, and whenever electricity and water are combined, there is a heightened risk of electric shock. The GFCI monitors the current flowing through the circuit and interrupts the electrical flow if it detects an imbalance, which could indicate that electricity is leaking through an unintended path, such as a person who has come into contact with water.

This requirement is particularly crucial in settings such as bathrooms, kitchens, and outdoor areas where water may come into contact with electrical devices. Ensuring that GFCIs are installed in these situations significantly enhances safety by reducing the risk of electric shock for individuals using electrical appliances or tools near water sources.
