Ground Fault Circuit Interrupters: What are They and How Do They Work?

Nov 14, 2018 | Electrical Safety, Licensed Electrician Tips

Ground fault circuit interrupters (GFCIs) are crucial safety devices commonly found in power outlets across many homes, yet their functionality remains misunderstood by the majority. These innovative outlets, also known as GFCI outlets, serve a critical purpose in mitigating the risk of electrocution by swiftly interrupting the flow of electricity upon detecting a fault in the circuit.

In essence, GFCIs constantly monitor the electrical current flowing through them, comparing the outgoing and returning currents. If a discrepancy is detected, such as electricity leaking from the circuit due to a ground fault, the GFCI reacts instantaneously by tripping and cutting off the power supply within a fraction of a second. This rapid response significantly reduces the likelihood of severe electric shock, safeguarding individuals from potentially life-threatening accidents.

Understanding the importance of GFCIs is paramount for homeowners seeking to enhance the safety of their electrical systems. By installing these protective outlets, households can effectively minimize the risk of electrical hazards, particularly in areas prone to moisture such as kitchens, bathrooms, and outdoor spaces. Prioritizing GFCI installation and educating oneself on their operation can ultimately save lives and prevent dangerous electrical incidents within the home.

How do Ground Fault Circuit Interrupters Work?

Ground fault circuit interrupters monitor the flow of electricity running through an outlet, and if there is a fluctuation in that flow, they cut off the power supply. When a person is electrocuted, they act as a conduit for electricity to flow through into the ground. This draws power from a circuit. By comparing the amount of power flowing out of an outlet with the amount coming back in, a GFCI can detect when any unregulated electricity leaves the circuit.

If the GFCI outlet senses that electricity has left a circuit improperly, it cuts off the power supply within 1/40 of a second, preventing severe electrocution. The person may still receive a shock, but ground fault circuit interrupters prevent that shock from being lethal.

Why Install Ground Fault Circuit Interrupters?

In most provinces, switching out regular power outlets with GFCI outlets in many areas of a home or business is legally required. Rooms with moisture, like washrooms and kitchens, must have ground fault circuit interrupters installed if is legally required it is legally required or safe. GFCI outlets help prevent electrocution and can save your life if an electric appliance or outlet malfunctions.
