This came up elsewhere and I am just curious about what the answer is.

If someone has a main service panel with a 200-amp main breaker, how
many
amps of service can that panel actually service?

I am probably not wording this correctly, but I thought that I remember
something about a 200-amp main breaker actually being okay for 400 amps
of
service since there are two separate circuits coming in (a 240-volt
service
split into two 120-volt circuits in the panel box).

DON'T DO IT!

Don't do what? A 200 amp panel will support 240V at 200 amps or 400 amps
at 120V.


200 amps. is 200 if is 120 or 240, You can not change Amperage
Voltage yes Amperage "NO" for 240 Volt max. is 200 amps./leg
Each "leg" of 120 Volt, will give max. 200 amps.
assuming that neutral is rated for 400 amps.
