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).

question. if your only supplying a transformer with a 100amp 480v wire is it possible to get 200amps 208v on the secondary of that transformer?


Watts in equals watts out.Â* Assuming the proper wire sizes on the primary and secondary, it's just simple algebra:

480V * 100A = xA * 208V

48000W = xA * 208V

48000W / 208V = xA

230.77A
