What's the standard rule on the older horizontal or "side-by-side" QOT tandem breakers about which switch controls which circuit, since one of the hot wires is stacked or hidden behind the other?
Thanks!
Thanks!

Are you talking about the breakers being double tapped which is not allowed. One breaker one wire.I have ordered a couple of identical spares of this type breaker that I'll have in hand in a couple of days, at which time of course I can simply use an ohmmeter to answer my own question, but in the meantime here's a photo of five QOT2020's in this older style that are currently installed in my 1979 vintage QO 30-40MW200 load center. All these have the CTL "hook". There are authorized positions for 10 of these breakers in this particular panel. It appears that the more modern QO load center tandems have two vertically stacked switches, and the hot wire connectors are also visible and side by side, unlike these.

There is no standard rule for random breakers. They are designed to be able to add more circuits since a standard breaker is 1 inch and tandem breakers are 1/2 inch but still only one wire isI have ordered a couple of identical spares of this type breaker that I'll have in hand in a couple of days, at which time of course I can simply use an ohmmeter to answer my own question, but in the meantime here's a photo of five QOT2020's in this older style that are currently installed in my 1979 vintage QO 30-40MW200 load center.
