What does QO stand for?
#3
The QO is a quality product, but today I think of it more like "Quik-Open" your wallet! QO used to always be a little more expensive, but today they are closer to 3 X most other brands. I don't think the quality is that much better than their competition.

I just bought a small panel, and standard breakers are not that much more than the others. Gfci's otoh, WOW!
#7
The QO seriés are 3/4 inch wide while the Homeline seriés is a full inch wide so they are not interchangeable so keep that in your mind.
It the same thing with couple other breaker manufacters as well they do make 3/4 inch and full inch verison but I know other manufacter do make skinny half inch single pole and one inch two pole breakers { not my favour items ugh.,, will discuss that other time }
Merci.

Do you have any data to support the assertation that QO and Homeline are the same? All of the literature put out by Square D (such as the obviously different trip curves) supports that they are completely different product lines.
#11
I actually had a Square D rep tell me they were the same too (about the time Homeline was brought out), but considering the price difference, I don't see how they could be. If the trip curves are different, they would definitely not be the same inside the molded cases. Homeline was first brought out to be a competitive line for the residential market. It's not likely they would repackage a premium product and sell it so much cheaper.

I have actually heard and see the guts between the HOMELINE seriés et QO seriés and I did took one each apart myself and both have same guts however there is couple diffrence between the two one is the handle design and the indentaction window with orange flag but everything else is the same but the mounting bracket is different as well.
The HOMELINE seriés did show up not too long after failed Trinait seriés breaker plus load centre { they are pretty unuseal design IMO I like it but not too many electricians like it for some reason some claim it too " European " style.
Merci.

That's simple, to be competitive. 30 years ago QO series panels and breakers were just a little more expensive than the competition, but today QO products are a lot more expensive. I think it was the late '80s when Schneider Electric bought Square D and brought out the Homeline series as a competitive residential line. Today's residential market is cutthroat and bids are awarded on the basis of nickels and dimes difference in bids. It's hard to be a low bidder when your service equipment is at least twice the price of your competitor. You can talk about quality all you want, but it's a hard to argument to make when even the aluminum bus cheapy panel meets code and is also U.L. Listed.

Yes, and so did good old Arrow-Hart Murray, Crouse-Hinds, Bryant, General Switch, Sylvania (Challenger), Westinghouse, Sears Roebuck and many others. Even today, you can get aluminum bus in Siemens, GE and Cutler-Hammer BR unless you pay a little more for their copper bus. Homeline is the only current residential single phase panel I am aware of that does not offer optional copper bus. If you want Square D copper bus, you buy QO series.

To be fair modern panels have hardened aluminum alloy buses with tin or silver alloy plating to prevent corrosion, so the "aluminum bus" of today is much different than the one of Zinsco era which was almost pure aluminum with little metallurgical treatment. It is really more appropriate to consider them completely different materials even though the primary component in each is aluminum.

ALL NEMA1 panelboards that accept bolt-on style breakers in this country come with standard aluminum bus (tin plated), regardless of manufacturer, including Square D, while some NEMA3R panelboards come standard with copper bus.

The 3r QO panel I just bought has an aluminum bus
•Exclusive shielded copper bus features electro tin plated copper bus bars sandwiched between two rugged polymer shields to insulate and secure the interior.

Sure this something it pretty rare item now I know it was made in early 1980's they only stay in the market for short while and faded out fast I do not know excat why but this style I like it but if they hang on little longer with better design it will be around.
That is one of very rare item I know not very many places still have it.
Merci.

Justin.,
To answer your question.,,
1., Oui it is plastique tub set up
2., The bussbar is resversed of what normal QO bussbar is and the Trilliant breaker C clip is turned 90° around IIRC.
Few Electrical contractors like it but most don't due they are pretty much standarized with steel tub.
Most European load centres will have mixed bag of plastique or steel tubs depending on useage.
Merci.
