What does GFCI stand for?

• A. General fault circuit indicator
• B. Ground-fault circuit interrupter
• C. Grounded fault current isolator
• D. Global fault circuit interruptor

Answer: (B)

The correct answer is Ground-fault circuit interrupter. A GFCI is a crucial safety device designed to protect people from electric shock by monitoring the amount of current flowing through a circuit. If it detects an imbalance between the outgoing and incoming current—often indicating that electricity is escaping to the ground, which can happen if a person is in contact with a live wire—the GFCI quickly interrupts the circuit, thereby preventing serious injury or even death. This device is particularly important in wet areas such as kitchens and bathrooms where the risk of electrical shock is higher. Understanding the function of a GFCI is essential for maintaining workplace safety, especially in environments where electrical equipment is used near water.
