some like GE have 2 handles(twice as wide) and again are attached by a pin so if one trips it turns off the other breaker.

Just an fyi, the common trip mechanism in a double pole breaker is internal to the breakers, it does not depend on a pin in the handles. You can get handle ties to join two single pole breakers together, but that does not make them common trip, it just makes it very hard to turn one off manually without turning off the other. That is why, as you say:

Using 2 seperate 120v breakers for 240v is NOT code and a safety issue

P.S. This latest subthread should really be in its own thread.

Agree, I wasn't trying to say one could make a 2 pole breaker out of a single pole breaker but rather I was trying to point out to kmand that often times a 2 pole breaker will look like 2 single pole breakers(2 separate but joined handles). Now SquareD 2 pole breakers actually look like a single pole breaker(only one handle) although twice as wide as a standard breaker. I'm a fan of the GE style as sometimes it's hard to tell from the outside if a SquareD breaker is 2 pole or 1 or even 3 in the case of 3 phase power. Of course with the cover off the panel it's easy to tell.
Agree on your last point also

I should have looked earlier, the TWO 20 amp breakers are indeed connected together.

As far as the compressor, the only reference to HP is a line on the label that says

O.D. MOT 0.70 FLA 200/230V 1/8 HP.

It's a 2 ton unit.

I (and 400K others) are on the Tesla 3 waiting list. I'm wondering if a modified Nissan EVSE would work on the Tesla?

Tesla should work with J1772 (either 120-volt L1 or 208/240-volt L2) so a modified Nissan EVSE would be fine (but rather slow for a large battery). For you application near the A/C unit either a NEMA 6-20 or L6-20 receptacle would be the correct choice with a suitable transfer switch.
