Wire Size 20, Breaker - You may sincerely see the 2 buses and that there doesn't look like any shenanigans connecting the 2 of them. I eliminated the top double-pole breaker for clarity. The popped dryer breaker is surely a single pole, as you may see the only entry slot. It's seemingly connected to the left bus and best that bus.
It appears like you may be incorrect as to how that is stressed, or that perhaps i'm simply no longer understanding your clarification. As others have mentioned, it's no longer viable to get 240 volts from a single pole in a 120/240v split phase machine. Each tandem breaker offers 2 120 v circuits, this is true. However, in case you measure among the terminals on a single tandem breaker, you'll get 0 volts. This is due to the fact the terminals are both powered from the identical leg, and so are on the equal voltage ability. If you degree from a terminal at the pinnacle tandem breaker to a terminal on the bottom one, then you will degree 240 volts. This is because each breaker is attached to a special leg, which can be each one half of a 240 volt circuit.
I ran across a panel these days that has a water heater and a dryer mounted the usage of tandem breakers. They're not split either. This panel is configurable to half of a slot, which means a normal 110vac breaker might be clipped into 2 prongs of a stay bus, and there is a small plastic wall keeping apart the b side from the a side keeping you from shorting the 2 110vac circuits together. However, the tandem breakers have a slot cut out allowing you to plug into each aspects. Each side of the tandem breaker receives its own feed from its personal prong on the buses making 220vac.
Within the case of the dryer circuit, there's one 10/three nm wire, with the hot black attached to one of the sides of the tandem breaker and the hot crimson attached to the other side. The neutral is connected to the impartial bar. Inside the water heater case, there is a ten/2, with each the white and black attached to their respective aspects of the tandem breaker.
