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).
If you apply 240-Volt to the load and have 200 Amps current, you've got 48 KVA. If you apply 120-volt and have a 200 amps, you've got 24 KVA. If you connect 200 Amps load to each of 120-volt leg, you've got 48 KVA total.
And no 400A anywhere.
