What are advantages of gfci circuit breakers?

Advantage #1 - Shock Prevention The most obvious advantage of a GFCI outlet is that it prevents shocks and electrocution. A GFCI outlet has a built-in sensor that monitors the inflow and outflow of electricity from an appliance. For example, if a live wire inside an appliance is in contact with the metallic surface of the appliance, then, you will receive a shock if you touch this appliance. However, if the appliance is plugged into a GFCI outlet, then the GFCI will notice the change in electrical flow occurring as result of the loose wire, and it will immediately shut down the power. Thus, GFCI outlets are necessary for shock prevention. Although they are slightly more expensive than regular power outlets, this massive advantage makes them well worth the additional cost.

Advantage #2 - Fire PreventionThe primary function of a GFCI outlet is to detect ground faults. Since ground faults, which occur when the flow of the electrical current leaves a circuit, can cause electrical fires, it is safe to say that one of the advantages of installing a GFCI outlet is the prevention of fires. Although electrical fuses do offer basic protection against electrical fires, when they are combined with a GFCI outlet, you never have to worry about an electrical fire harming your home or workplace.

Advantage #3 - Prevention of Damage of Appliances Sometimes, over a period of time, as insulation breaks down, a certain amount of electric current begins to leak into household appliances or other electronic items. If the outer body of the equipment is not made of metal, you may not get a shock, but this constant leakage of current will damage the equipment. In fact, this leakage of electricity is one of the most common reasons why computer hard disk drives fail. With a GFCI outlet, you do not need to worry about this happening. This is because the instant the GFCI circuit detects a leak, it will shut down the circuit. This can help prevent expensive equipment and appliances from getting damaged due to electrical leaks.
