Another 1st today. Why are these tied together? (I did not remove the panel cover)
This is the answer, I am sure. But this is for an added finished basement, and I want to ensure it is not a short-cut.

Must be the bus/ocpd configuration, eh?

Yeah. It appears ok. I just have not seen this before and I have seen lot. I guess it is the only way to get two into that space.

From California, it looks like three 240 volt circuits for three air handlers. The sharpie even shows where the wires go inside. They’re common trip internally, according to the fuzzy label on the BR quad.
If it’s two 120V 25V circuits that’s cool also, they just go off at the same time. Just a regular Multiwire Branch Circuit Problably.

The bottom is a quad breaker. Effectively two 2 pole breakers in the space of 1. The inners are one brea,er, the outers are the second breaker.

All good Brian.
I concur, Jim. 4 pole breaker.
Eaton BR420 Plug-On Mount Type BR Circuit Breaker 4-Pole 25 Amp 120/240 Volt AC servicing A-C 3 & A-C 2.
Brian, how is the HVAC set up? How many exterior Compressors. Furnaces/AHU and condensers?
There are three.
It must be a regional thing, but I’ve seen this a bit here in FL. I also saw it up north in my prior profession, but that stuff was industrial or commercial. I was a little surprised to see it on homes, but it’s just a quad breaker. Shrug.

For 240v circuits, both 120v legs need to be tied together to ensure both legs get turned off together. In this particular configuration, due to the arrangement of the interior bus, the only way to grab (2) 240v circuits is by utilizing the top connection on the breaker, along with the bottom connection as one of the 240v circuits, and by utilizing the center two connections as the other 240v circuit.
The end result is the funky handle tie set up you see in your pic.

Agreed, & I see it quite a bit actually.
