Square D by Schneider Electric QO Plug-On Neutral 20 Amp Single-Pole Dual Function (CAFCI and GFCI) Circuit Breaker

What I like about these breakers is they work like they should and their half the price on here then they are at your local hardware store. They have never blowed anything and they keep my electric running like it's suppose to run.Very good product!

AFCI and GFCI built into the breaker. No separate devices to install in line. One place to go to test all of your AFCI and GFCI circuits. Arc-fault protection for the entire cable run, not just from an in-wall device onward. Trips instantly and reliably with simulated arc faults and ground faults at outlets. This device provides a very high degree of confidence in the safety of the circuits it protects. Looking forward to replacing my main panel with a QO plug-on neutral panel in the near future so I can extend this protection to the entire house, not just the circuits on the addition subpanel (although I'm slightly less excited about the cost, it's cheap insurance).If you haven't worked with Square D's innovative plug-on neutral system yet, you owe it to yourself to give it a try on your next residential panel job. No more neutral pigtails crowding the inside of your panel installs. Just a nice, neat install with hots and neutrals straight to the GFCI, AFCI, and dual-purpose breakers and ground to the ground bar. The inside of the panel looks so clean you'll feel bad about putting the cover on.My only, relatively minor complaint is that due to the size and relative heft of these breakers, gravity wants to pull them slightly downward when the cover is off of the panel (not to the extent of falling out or anything like that - just a very, very slight tilt. When the cover goes on, everything stays securely in place. Not worthy of a star downgrade, just something to be aware of.

Installed a new Square D 100 amp panel in my garage/workshop. The panel has the plug-on neutral bar which is compatible with the combination Square D CAFCI and GFCI breakers. The plug-on neutral is a great feature and the panel looks nice and neat when completed. The combo CAFCI and GFCI breakers are expensive but since I was installing the panel in a garage with several outdoor outlets, I wanted the combo breakers. This also eliminates the need to install separate GFCI outlets for code and safety compliance which reduces some of the cost. Square D is a great product and the plug-on neutral breakers are recommended if you are putting in a new panel.

A cost effective solution to meet code requirements for residential combination circuits.

Specifications on Amazon say "3 x 3.2 x 0.7 inches", and this is 4.75 x 3.2 x 0.7, so it sticks out into the wiring trough almost 2 inches farther than other breakers. You may have room, but they go down to 1 star for putting the wrong size in the specs.Another issue is that both white and black wires from the circuit need to come to the breaker, so the GFCI can work by comparing current in each. Fine for new installation. Can be hard to replace an old non-GFCI breaker where the white wire is buried deep in the trough going to the neutral bar at the top, behind other wires. I wanted to put this new breaker on my old garbage disposal circuit, to have GFCI protection on the switch. Fishing out the white wire and bringing it to the breaker turned out to involve pulling all the other wires from the trough.
