Arc Fault Breaker Safety
Free online program on AFCI technology

There is a free online training program designed to teach safe and effective ways to install and troubleshoot issues with arc fault circuit interrupters (AFCIs).

The program is available for free through Knowledge Services, UL's fast-growing training, advisory and software solutions business unit.

The course will help electrical professionals complete trouble-free installation of AFCIs and provide expert advice on finding and fixing electrical system problems that may cause AFCIs to trip. The program targets those who install electrical systems in residences ?whether they are single, multifamily or apartment buildings ?where AFCIs are a National Electrical Code (NEC) requirement.

For More Information:
Working together the electrical fire safety industry created AFCIs to prevent electrical fires and save lives. Per Standards Boost Business, “By collaborating on a critical standard for Arc Fault Circuit Interrupters, the National Electrical Manufacturers Association, the National Fire Protection Association, and Underwriters Laboratories have helped to prevent more than 40,000 home fires, over 350 deaths, and more than 1,400 injuries each year.” Read more at


AFCI safety is sweeping the nation. To date, almost all of the country has adopted the 2011 National Electrical Code (NEC), which expands the requirement for arc fault circuit interrupters (AFCIs), electronic circuit breakers developed in response to an electrical problem causing home fires.

Each year, home electrical fires take the lives of 480 people, injure more than 2,000 and destroy more than $868 million in property. While working smoke alarms, fire extinguishers and other safety measures provide some life-saving help, it’s only after a fire starts. AFCIs detect dangerous electrical conditions and shut the circuit off before an electrical fire has a chance to ignite.
