GFCI breaker basics - Ground fault circuit interrupter how it works

The video tutorial explains the importance and functionality of GFCI circuit breakers. It covers the installation process, including the connection of hot, neutral, and ground wires, and highlights the necessity of adhering to the national electric code. The tutorial also demonstrates how GFCI breakers detect imbalances in current flow to prevent electrical accidents, ensuring safety by automatically tripping the breaker when a fault is detected.

What does GFCI stand for?

• General Fault Circuit Indicator

• General Fault Current Interrupter

• Ground Fault Circuit Interrupter

• Ground Fault Current Indicator

In which areas are GFCI breakers typically required?

• Living rooms and bedrooms

• Kitchens and bathrooms

• Garages and attics

• Offices and libraries

How does a GFCI breaker ensure safety?

• By measuring the voltage in the circuit

• By monitoring the power usage

• By checking the temperature of the wires

• By measuring the current in both hot and neutral wires

What is the purpose of the pigtail neutral wire in a GFCI breaker?

• To connect to the hot wire

• To provide a return path to the neutral bus bar

• To connect to the ground wire

• To measure the voltage

What happens when a GFCI detects an imbalance in current?

• It trips the breaker to cut the power

• It decreases the voltage

• It sends an alert to the user

• It increases the current flow
