In the U.S. single phase at 200 amps is average.
You can install up to four 50 amp single phase breakers on one phase of a three phase 200 amp panel, assuming the panel is balanced properly among the three phases. Each breaker will draw 50 amps of current, so be sure to consider the total load on the phase to prevent overloading.
For a 100 amp service, a minimum of 2-gauge copper or 1/0 aluminum entrance cable should be used.
The recommended size for a 100 amp service entrance cable is typically 2 AWG copper or 1/0 AWG aluminum.
The recommended cable size for a 200 amp service entrance is typically 2/0 AWG copper or 4/0 AWG aluminum.
For a 225 amp 3-phase service, typically you would use 3 sets of 3/0 AWG copper conductors or 250 kcmil aluminum conductors for the service entrance conductors. Make sure to consult the National Electrical Code (NEC) and local regulations for specific requirements.

100 or 105 amp.
Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
100amps
2 AWG Aluminum.
For a 100 amp electrical service, a service entrance cable of at least 2 AWG copper or 1/0 AWG aluminum should be used.
