Square D - ‎QO115CAFIC Arc Fault Breaker, Black

Works great, easy to install. Good price bought second one as preventative maintenance to replace another 20 year old breaker. Recommend.

Overall great product!

You need to be careful in purchasing these breakers because a) most codes require "CAFCI", not only "AFCI" - there are some old models being sold cheap, but will not pass inspection, and b) many of the choices will not fit in your panel, as they will be too wide. This is a CAFCI breakers and the width is .75 inches, and replaced a standard 15 amp home breaker in a standard Square D panel. On Amazon it was half the price of the big box stores - no idea why, but fear not - it is the right item. Not complicated, but do yourself and your loved ones a favor and hire a licensed electrician to install.

Item is as described. Item arrived three days prior to the scheduled delivery. It was well packed and nicely placed by the door. would definitely by again from this buyer.

Arc Fault Circuit Breakers for Square D QO Load CentersThis review is for non-electricians...I installed 18 one-pole AFCIs and 4 two-pole AFCIs 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.Pros:– breaker quality appears to be outstanding, but realistically, a customer has to trust Square D to have met design specs and for these breakers 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) circuit breakers in that they are MUCH wider, have a test button, the white & black circuit wires attach directly to the breaker, and there is an integral 18" coiled white wire to be connected to the neutral bar.Con:– Some electric motors (e.g., tools, vacuum cleaners) cause these breakers to trip. Most of my electric tools run fine on an AFCI, but some don’t. The trip can occur instantly or after a short while. Some will run most of the time but will occasionally trip the AFCI breaker. These are false trips, and Square D needs to fix this issue. Their warranty is useless when the replacement breaker also trips. One star off for this defect is a gift – as this defect renders it impossible to meet the new AFCI code in all rooms when you have Square D load centers.Other:– If the breakers are to be installed in your main panel, which typically can’t de-electrified, you need to be comfortable working with hot wires nearby. If not, hire an electrician. If working on a sub-panel, consider cutting power to that sub-panel before beginning work. AFCI breakers are about as simple to install as a light switch. 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 only work in a Plug-On Neutral Square D Load Center.– If buying 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 difference with the plug-on style load center is in the black breaker assembly where the circuit breakers are attached; i.e., the outer breaker snap rods are steel (rather than plastic) and those rods are electrically connected to the neutral bar.– While you have a load center cover off, you might want to re-tighten all neutral hold-down screws and existing breaker hold-down screws, as they may have loosened over time. Loose connections can result in arcing.– In my State, no electrical permit is required for a homeowner to replace circuit breakers, light switches, receptacles, light fixtures, etc.– Remove the load center cover to determine if there are any multi-wire circuits (MWC), before ordering AFCI breakers. (See comments for details.) Single pole AFCI breakers trip if installed on either half of a MWC; i.e., MWC circuits require two-pole AFCI breakers.– Upon installation or soon thereafter, a AFCI breaker may trip – see comments for resolution options.Summary:All 22 QO AFCI breakers worked fine, except as noted above. Should one go bad in the future, Square D has that lifetime warranty on the product.A wealthy Maryland family was killed in an electrical house fire recently. Their home was built prior to county code requiring sprinklers or AFCI circuit breakers. That fire convinced me that it was time to add arc-fault protection to our home’s breaker panels.

Connected this weekend, lights working fine. Pretty easy install one FYI (below).General FYI- if you are retro-fitting/replacing a standard breaker to bring a current circuit up to code- you will likely need to extend the White "Neutral" wire since you now need it to feed into the breaker itself instead of the Grounding Bar inside the panel. In my panel the grounding bar is near the top and circuit was midway down the line so I had to pigtail a connection and tape up to extend the wire 6" or so.these are about 30" longer than the standard breaker so mine all fit fine in my Panel but if your current ones are snug to the walls you may have trouble getting everything in comfortably.

I had an AFCI breaker go bad and bought this to replace it. Easy to install and snapped right into my box. A perfect replacement and much cheaper than the local big box stores.

Goes out much farther than the standard breakers. You may need to move some things around and really push to get it in. Also keep in mind you'll need to find the correct neutral wire for the circuit and connect that as well. If your romex was stripped off in the wall like mine it will take some testing to figure it out. Have had it trip from a small power outage. If it trips everytime we get a quick surge that is going to get old and make me mad, if I'm not home and my DVR doesn't record because it tripped from a quick power outage.Edit:2022 I ended up removing two of them and put the standard back in. They keep tripping when there is a power blip. This means if I'm not home my deep freeze isn't cooling, my cameras are not recording and my modem is offline. I have had to go out in the rain to reset one or more of the breakers because they tripped. If you search YouTube for my channel billybassman21 you can witness it while I was recording a storm in 2021. Can't risk having them trip when out of town. They should only trip from an overload or from arcing. I know there isn't an arcing going on. For whatever reason the GFCI's I installed that also do arc fault have only tripped once when no other did. I want the extra protection, but it isn't worth the risk.

Shipping was fast, breakers are perfect.

If homeowner upgrading from a standard breaker, take the time to fully comprehend the differences in installation. The CAFCI snaps right into the panel of course but its longer and, it has two screw terminals instead of just one and, it has a ground pigtail to be connected to the ground bar in the panel which, in an already cramped panel can be challenging and you may unexpectedly find yourself with a neutral wire that's not long enough to be moved from the neutral bar to the neutral screw on the cafci breaker.

updating an older home they were a great price and worked just as i hoped

An advanced breaker capable of analyzing series and parallel circuit faults. This is a push-on breaker and can only be installed on a Double D’ panel for this type. It meets the latest building codes when adding new circuits. The pigtail is too short to connect to the neutral bar in a 42 circuit panel if the breaker is located at the top four circuits spaces.

Best price available. No complaints, they will do the job. Exactly what I expectedExactly what I needed for a electrical job.
