Arc fault circuit interrupters (AFCI) are a new addition to circuit breakers, ensuring early detection of potential fire hazards and cutting off connections during unusual occurrences to prevent damage. However, as it is with any new technology, there are few myths that might cause your clients to second-guess an installation. Put their minds at ease by correcting the following misconceptions.

What Not to Believe About AFCI Circuit Breakers

1. AFCI Devices Tend Toward Nuisance Tripping

These breakers don’t usually trip for no reason. They use advanced technology to monitor the electricity that’s coursing through the system. If there’s a sudden surge, such as from turning on the vacuum or starting up the furnace, they will evaluate the conditions surrounding the event before determining a need to shut off the power. 

Manufacturers run several tests before putting their products on the market to ensure accurate readings. If there’s a trip that doesn’t reveal an immediate hazard, homeowners should take it as a safety alert and have their electric system inspected.

2. AFCI Breakers Only Protect Devices That Are Plugged Into a Particular Outlet

These devices are made to monitor the entire circuit, including the electrical panel, the wires in the walls, the outlets, the switches, and every other connection in the home. If an incident requires a shutdown, the system will detect its location and cut the current.

3. A Standard Breaker Provides the Same Amount of Protection

Standard breakers don’t contain the same technology as those in their AFCI counterparts. This limits their ability to protect the home and may cause them to overlook low-level arcing currents. As these can create fire hazards, upgrading your customers' panels will help to ensure timely detection and repair of problems.

4. Residential Codes Only Require AFCIs in Some Rooms

After their initial release in 1999, the National Electrical Code (NEC) has been studying the effectiveness of AFCI breakers in preventing electrical fires. They now require all homes to include these devices on circuits that lead to every room—including the closets—to maintain safety.
