    Circuit Protection and Fire Prevention (Living Room and Bedroom, Basement and Garage)

    Superior electrical safety for homeowners

    Electrical problems spark an estimated 51,000 home fires and cause more than $1 billion in residential property damage each year. (National Fire Protection Association, 2003-2007). Electrical wiring, cords, and plugs, switches, receptacles, and outlets can be the source of tremendous damage to your property or worse, your family. Protect yourself with Square D Circuit Breakers.

    Just like the airbags in your car and technology on your smartphone, circuit breakers are more advanced and sophisticated than ever before. Square D™ circuit breakers are engineered and designed to help keep you, your family, and your property safe from electrical hazards that were previously undetectable. A circuit breaker “trips” and shuts off power when it detects an issue on a circuit that could possibly cause an electrical fire.

    To help you better understand the protection of your home electrical system, let's take a look at two state-of-the-art types of circuit breakers for your bathroom.

    Combination Arc Fault Circuit Interrupters (CAFIs)

    CAFIs help provide protection against dangerous arcing; the precursor to many electrical fires. Square D QO™ and Homeline™ CAFIs help protect people and property from fires caused by electrical arcing. These devices continuously monitor the branch circuit and trip when a potentially dangerous condition is detected.

    Circuit Protection and Fire Prevention

    Ground Fault Circuit Interrupters (GFCIs)

    GFCIs are designed to protect people from the dangers of electrical shock. These circuit breakers are typically installed on circuits where water sources may be present. The National Electrical Code (NEC) requires ground fault circuit protection in the garage, outdoor areas, bathrooms, and in spa areas within the home.


    The QO and Homeline Ground Fault Circuit Breakers provide Class A protection, sensing and responding to very low levels of ground faults by tripping or shutting off power, preventing serious electrical shock to people.

    Dual Function (CAFI + GFI) Circuit Breakers

    The innovative Square D QO and Homeline Dual Function Circuit Breakers combine two critical, state-of-the-art technologies: Combination Arc Fault and Ground Fault (Class A) Protection in one circuit breaker. Dual Function Circuit Interrupters provide a higher level of protection than any other residential circuit breaker. These devices combine both Ground Fault Protection and Combination Arc Fault Protection in a single device. And these devices protect the entire circuit on which they are installed, not just a part of the circuit like electronic receptacles (GFI or AFI) do.
    The U.S. Consumer Product Safety Commission (CPSC) estimates that Combination Arc Fault Interrupters could prevent more than fifty percent of electrical fires that occur every year.
