The example given in your .png showed AB....AB on the left,

sense and would require some goofy bus work to accomplish.

I wish whoever kept posting that PDF would have known that
and not posted it then, because that's what we were going on.

So, the top two bus tabs, inline from left to right are phase A.
The next row down will be phase B, inline from left to right.

Makes sense.

A 2-pole breaker will take up two spaces, top
to bottom and will give you both an A and a B phase.

I like that we can *see* that, given there are two hots coming
out of the 240V breaker, so, it *must* be phase A & B.

Meaning that if you where to have black and red wires denoting
phasing, the black would go on A, and the red would go on B.

This is an interesting observation.

Black is always A, Red is always B

Ah. This is news to me. So, all reds, in the breaker panel, would
be B then. But, isn't this red wire on A?

Here's a further-out view of that same breaker:

Since the red is on top, isn't that phase A (and not phase B)?
