SquareD QOC24UC

How many circuits are allowed in a Square D QOC24UC panel?
My understanding is 24 circuits maximum is allowed.

Do you have a photo of the bus diagram from the label?

Unfortunately, that is all I have (attached) and yes I noted the double tap neutral. Thanks again Robert!

Your second photo in post #1 with the model number is for the cover {QOC24uc}. The catalog number for the panelboard should be QO320ML1 which allows 20 full size or 40 tandem CB’s. Look here:

OK thanks!

Robert is correct. We call that a 20/40 panel. Meaning 20 full size breakers but if you some double breakers ( not 2 pole) you can not have more 40 circuits total.
