AFCI stands for Arc Fault Circuit Interrupter. It is an electrical safety device designed to detect and mitigate the risk of electrical fires caused by arching faults in wiring, cords, and electrical devices.
What is the difference between AFCI and GFCI outlets?
GFCIs are designed to protect against ground faults or ground leakage currents. They detect imbalances in the electrical current flowing a circuit, which can occur when current leaks to the ground – for example, due to contact with water. They are primarily used to prevent electrical shock hazards.
AFCI are designed to detect and mitigate the risk of electrical fires caused by arc faults. They are sensitive to abnormal electrical arching, which can happen when wiring is damaged, cords are frayed, or there are loose connections. AFCIs focus on fire prevention.
How to know the difference in GFCI and AFCI?
GFCI: Look for the outlets with ‘test” and ‘reset’ buttons, these are typically GFCI outlets. They may also have a GFCI label on them. GFCI outlets are often installed in areas near water sources, such as kitchens, bathrooms, garages, and outdoor locations
AFCI: AFCI protection is usually provided by circuit breakers rather than outlets. Check your electrical panel for circuit breakers with AFCI labels or test buttons. These breakers are often used to protect bedroom and living area circuits.
What if neither AFCI or GFCI is present?
Determine the level of risk associated with the area or circuit in question. Consider factors such as proximity to water sources, the presence of electrical devices, and the age of your electrical system. High-risk areas should have appropriate protection.
Depending on the specific need, you can install AFCI or GFCI protection where it’s lacking. You can retrofit existing outlets with GFCI receptacles or add AFCI.
If you are unsure about the protection in your home, need to identify specific circuits, or the best course of action, it’s a good idea to consult a reputable licensed electrician.
AFCI and GFCI devices are critical for reducing the risk of electrical fires, electric shocks, and other electrical hazards in your home. Ensuring their presence where needed is an essential aspect of home safety.
