You will need to use #8 wire.
For a 250 amp load, a cable size of at least 3/0 AWG (American Wire Gauge) or 70mm^2 is recommended. For a 160 amp load, a cable size of at least 1/0 AWG (American Wire Gauge) or 50mm^2 is recommended. It is important to consult local electrical codes and regulations to ensure compliance.
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.
#10 cable is no good for 120 amps, you need #2 cable, and it can be used at a distance of 250 ft.
If you use 250 or 300 MCM wire you will need a 2 1/2" weather head. If you use 300 MCM wire then you will need a 3" weather head.

Depends on the size of the circuit which you did not list.
