Two 200A 120V loads in series makes a 200A 240V load.

It's a very basic and simple electrical question as to how many amps

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

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. Lets say I had forty 10 amp,
120volt heaters. I could could clearly put twenty of them between one
leg and neutral and twenty between the other leg and neutral and it
would work. You now have a fully loaded balanced service. There
is zero current flowing in the neutral and 200 amps flowing in the
service. It works because the loads on one side are connected in
series to the loads on the other side.

My whole point all along has been that the actual current in a 200
amps service is limited to 200 amps which clearly you agee with.
And it has nothing to do with "parallel circuits", or power, voltage
or anything else. It looks like the only difference we have is your
definition of "supporting loads" may be stricter than mine.

And I think all of us are still waiting for a simple answer from Doug
as to how many amps are actually flowing in a fully loaded 200 amp
service cable circuit. I've asked that several times now and still
have no answer, despite having fully answered all his questions.
