The only way you can get 400A out of a 200A service is with a step-down

I think we are in agreement, except for perhaps one point.

From your previous post, you clearly agree that you can in fact have
two 120volt, 200 amp loads connected in series across the 240volt
service. That is a perfectly balanced load. You now have 200 amps
flowing in series through each load. In my world that is in fact
"supporting" 400 amps of 120volt load.

Your semantics create confusion. In NO CASE can you flow more than 200 amps
through any single load. To say that you have many 120V loads drawing a
total of 400A is WRONG and obscures the fact that two balanced 120V loads is
absolutely identical to a 240V load.
