From the Manufacturer

Square D QO Combination Arc Fault Circuit Interrupters, 1-Pole, 20-amp

Reliable, safe, easy to install

Square D QO Combination Arc Fault Circuit Interrupter, 1-Pole, 20-amp

Backside of circuit breaker

Provide enhanced protection against home electrical fires

Unlike standard thermal-magnetic circuit breakers that cannot detect dangerous arcs, Combination Arc Fault Circuit Interrupter (CAFCI) circuit breakers detect arcs and shut down a circuit before a fire starts. Advanced electronic technology monitors the circuit for the presence of dangerous arcing conditions. If such conditions are observed, the circuit breaker trips, cutting off the current and voltage to the arc fault, helping to keep people and property safe.

Meets National Electrical Code requirements

Square D Combination Arc Fault Circuit Interrupters are the first commercially available circuit breaker designed to meet the National Electrical Code (NEC) requirements for Combination AFCI protection. They provide the highest level of arc fault protection on the market today, protecting against both serial and parallel arcs for the entire circuit.

What is an arc fault?

An arc fault occurs when electricity is unintentionally released from home wiring, cords, or appliances because of damage or improper installation. This release of electricity can cause surrounding material to catch fire. According to the National Fire Protection Association, electrical arcing is the source of ignition in more than 30,000 fires each year. These fires cause hundreds of deaths and injuries and more than $750 million in direct property damage.

(No text entered for this element)

A Consumer Product Safety Commission report revealed that electrical fires in existing homes may be attributed to several factors, including improper alterations, deterioration due to aging, and faulty products. Top causes of arc faults include frayed cords, overheated wires, rodents chewing on wires, and pierced wire insulation, such as a wire inside a wall nipped by a nail.

Wiring damage causes arc faults

TIME SAVER Diagnostics shows why a trip occurred

TIME SAVER Diagnostics helps take away the guesswork and provides diagnostic assistance at the touch of a button in the unlikely event a trip should occur. By identifying the type of fault that has occurred, it improves troubleshooting time and helps contractors and homeowners identify the trip cause faster. The TIME SAVER Diagnostics sequence is simple and easy to use, and requires no tools or special training. Simply turn off the circuit breaker, hold down the Push-To-Test button, and then turn the circuit breaker back on. Equipped in all Square D QO(B) CAFCI and Dual Function Circuit Breakers with a date code of 1130 or higher.

  • Safe – Square D CAFI circuit breakers detect a wider range and increased number of arc faults than a standard circuit breaker, improving the safety of an electrical system.
  • Easy-to-use – Equipped with simple and effective TIME SAVER Diagnostics, it provides circuit information at the touch of a button.
  • Reliable – Engineered with the quality and craftsmanship that have made Square D the preferred brand of electricians and homeowners for over 50 years.

Combination Arc Fault Circuit Breakers for Square D QO Load Centers

This review is for non-electricians...

I installed 18 one-pole combination AFCIs and 4 two-pole CAFCIs in a 30-year-old house with a Square D QO load center and three QO sub-panels. I also replaced an old 12-space sub-panel with a Square D 24-space Plug-On Neutral Load Center.

– product quality appears to be outstanding, but realistically, a customer has to trust Square D’s breakers to meet design specs and to last. The lifetime replacement warranty is a testament to the manufacturer’s confidence of quality.

– these differ in appearance from standard (non-AFCI, non-GFCI) breakers in that they are MUCH wider, have a test button, the white & black circuit wires attach directly to the breaker, and the 18" coiled white wire is to be connected to the neutral bar.

Other:

– if you are comfortable working on live panels, AFCI breakers are about as simple to install as a light switch; otherwise, hire an electrician. (If working on a sub-panel, consider cutting the power to that sub-panel before beginning work.) Square D “plug-on neutral” breakers are easier/quicker to install and result in less wiring clutter within a panel, since they lack the pig-tail white neutral wire – BUT, they work only in a Plug-On Neutral Square D Load Center.

– If you’re installing a new Square D load center, get the plug-on style since plug-on or non-plug-on Square D breakers work in them. The only difference with the plug-on style load center is the black breaker assembly; i.e., the outer breaker snap rods are steel (rather than plastic) and those rods are connected to the neutral bar.

It works great, came tripped (means it's brandy-new) and tested working. Also, as a tip for DIY homeowners (like myself), make sure you cut the pigtail to size so you don't have a bunch of extra wire in the panel, and that you have a stripping tool with a gauge for stranded wire.

Square D breakers are what I have and I am glad that I do replaced a standard 20 breaker with this and now the bedrooms are protected with AFCI which was the goal. Very easy to install.
