200 amp x .8 ( for continuous duty ) = 160 amps x 240 Volt = 38,400 watts .
This is single phase , assuming 3/0 copper THHN .
200 amp 3 phase x .8 ( for continuous duty ) = 160 amps x 3 x120 Volt = 57,600 Watts .
This is 3 phase 120/208 Volt , assuming 3/0 copper THHN .
Would be slightly more for 3 phase 120/240 Volt .

God bless
