Default Load capacity of 200-amp panel
In article , says...

Watts in equals watts out.* 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




You need to factor in the loss in the transformer. Many are around 95
to 98 % efficent so maybe a 5 % loss or less. You still would have
about 215 or more amps to use.
