Items are good. Snap on style, very clean

Hate the fact that these are so expensive, but love Square D quality and functionality. Replaced a Murray (Which breaker tripped? Who knows?) load center with Square D 40/40/200 panel, and have no regrets.

Prompt delivery, quality device, and great price; what else can you ask for?

Works as described.

Several months ago I installed a new QO electrical panel and QO plug-on AFCI and AFCI/GFCI breakers (after getting permits and passing the county electrical test) and am very happy with all of the hardware and with Schneider customer service. My old panel was a QO, over 40 years old, which was small and had mostly tandem breakers. I did plenty of research before taking the plunge into the world of AFCI -- I wanted the assurance that AFCI provides but was very wary of the false tripping so often written about in AFCI reviews. Schneider's QO AFCI breakers seemed to have the least number of false tripping issues reported. They're a bit more expensive -- you get what you pay for in this case!

Well, after 4 months I can report that false tripping is a non-event for me (actually, to date only one trip, on an AFCI/GFCI breaker, when a hairdryer tripped it so it might not have been a "false" trip).

I did however find 2 circuits that had problems that required changes. Immediately upon installation of the new panel/breakers one circuit would not stay "on" -- it tripped immediately if I tried to flip it on. I checked each of the outlets on the circuit and found one where the neutral and ground were touching. I fixed that quickly and have not had a problem with that circuit since. (A nice feature of switching to AFCI's is that, in addition to the security of knowing you'll avoid future fires caused by arc faulting -- the major cause of house fires -- you'll also find out if your house wiring has issues that could cause a future fire). The other circuit where I had a problem included the garage door opener. That circuit was too heavily loaded and tripped occasionally when I started the opener. I rewired the circuit to reduce the load and haven't had a trip since. Again, the use of the AFCI/GFCI breaker uncovered an existing issue -- the new breakers are more sensitive than the old ones I replaced.

The installation process was very straightforward. The plug-on feature reduces the amount of wiring and helps keep the panel cleaner/less packed. The breakers snap in to place, although they aren't as firm as bolt on breakers would be. The panel cover solves this by keeping the breakers tight.

My conclusion on the switch to AFCI breakers, at least the Scheider QO type, is that when tripping happens, there's a good reason that needs to be addressed -- its not really 'false tripping'. False tripping fears unfounded, installation easy -- I'm a very happy Schneider customer (I'm travelingnana's husband, in case you're wondering!).
