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.
Yes, a 20 amp electrical service can be upgraded to a 40 amp service, but it requires careful planning and adherence to local electrical codes. This upgrade typically involves replacing the existing circuit breaker panel, wiring, and potentially the service entrance cable to accommodate the increased load. It's essential to consult a licensed electrician to assess your home's electrical needs and ensure a safe installation.
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.

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".
