The issue of wire size is ALWAYS dependent on what sort of current MAY
occur even in a fault condition. The wire must be increased in cross
section if there are heat retaining conditions such as conduit, insulation,
limited possibility of convective cooling.
So you don't size the wire based on an

On a 20 amp breaker, definitely. On a 30 amp breaker, probably not.
I don't have a copy of the NEC handy, and I'm not a code expert, but IIRC
the code has (or had) a provision for using a size smaller
I'm not a code expert, but as I understand it, in the addition to what Jay
Summet said, the NEC generally prohibits connecting either 15 or 20 amp
receptacles to a 30 amp branch circuit. Receptacles must be 30 amp. The
fact that you're allowed to connect 15 amp 120v recepts to a 20 amp branch
Correct, a 240v circuit can overload one leg and the ganged breakers will
trip. That is why it has a pair of ganged breakers.

Thanks for your insight. Yes, the breaker will be 20 amps so if anyone
tries to do anything other than a single L2 or two L1's they will loose
both as the breaker will trip. I do assume that a 20A 2 pole breaker
actually will trip based on an overload on either of the two sides

I install two 120v outlets on each post along with a single 240v outlet.
And then a small note says, "Either one L2 or two L1's but not both".
Each post has properly rated #10 conductors for the 16 amps on Line1 and
Line2 and Ground and a #12 for Neutral since the Neutral carries either
