The American Circuit Breaker Manufacturer’s Association (ACBMA) highlights why dual function circuit breakers provide the best protection for homes.Watch the video
Over 30% of circuits in the average home are “home run” circuits. That’s the distance from the load center to the first outlet. Wiring device manufacturers try and convince you that outlet AFCI/GFCI devices are just as safe as using dual function circuit breakers. Fact is, they’re not. Their outlet based AFCI/GFCI protection can’t always protect a home upstream (for parallel arcing conditions). Dual Function circuit breakers are recommended to protect the entire system from the load center.
Here's what device manufacturers who sell AFCI/GFCI combinations outlets forget to tell you and electricians:
The current supplied by utilities can vary. When it approaches 500 Amps of “fault current” or the amount of current to cause harm if there is an electrical fault (such as a short circuit or arcing condition), you need approved products that will interrupt that current 100% of the time. Those are circuit breakers. They’re designed to handle that responsibility. Square D™ has been manufacturing Arc Fault Circuit Interruptors (AFCI) since 1999. We have almost 20 years of experience and can detect these dangerous faults to safeguard a home. Why leave 30% or more of your house at risk?
Our Dual Function circuit breakers, with built-in AFCI and GFCI protection, save space and eliminate the need for AFCI/GFCI outlets on the circuits they protect. Imagine only having to go to one location to discover where you’ve “tripped” a circuit. No more hunting around for GFCI outlets. When installed in our Plug-on Neutral load centers, the overall cost is actually less than using AFCI/GFCI outlets.
