Double Pole Square D - double tapped?

Basically 30 amp and less "standard" 1 through 3 pole QO breakers that have the pressure plate design terminals are listed for one or two conductors, I believe 14-10 AWG. They typically accept up to 8 AWG but I think only one conductor is mentioned for 8 AWG.

GFCI, AFCI breakers have the pressure plate design, but the case is molded so that one side isn't accessible and therefore they are rated for only single conductor per terminal.

Breakers over 30 amps don't have the pressure plate type terminals and are only rated for a single conductor, same goes for tandem breakers.

I have seen older 15-30 amp breakers with a different termination style that only accepted single conductor, but they have been using the current termination style with very minimal changes for at least 40-50 years now.

I think you will find about the same things for the Homeline series.

I didn't really have a question, I did look at the link, I use enough Square D products that I didn't learn anything from it in regards to how many conductors/what size can land on the terminations.

Well, it seems as though you weren't very sure of yourself when you used the terms "I believe" and "I think only one conductor is mentioned for 8 AWG" so the link cleared it up for you.

Fair enough, my choice of words wasn't that great.

My daughter's home built in the early 60s has a QO panel. Those breakers still have the pressure plate. The main differences between them and modern ones are slotted screws vs. Robinson, and it's almost impossible to read the amp rating without good light.

I can't recall seeing the pressure plate terminal on any QO breaker made before they added the "visi-trip" indicator.

Have occasionally seen ones with "push-in" wire terminal. Mostly on some of the old tandems with full width handles.

Lack of visi-trip is another difference.

You have me wondering now. I'll look at them again next time I'm there.
