To calculate the wire size, a system voltage is needed.
The wire size used in a service entrance distribution panel is governed by the size of the services over current device. The larger the service, the larger the fault current could be, the larger the ground wire to carry the fault current to ground. If the largest service conductor carries 100 amps use a #8, 200 amps - #6, 400 amps - #3, 600 amps - #1, 800 amps - 1/0 and over 800 amps - 2/0 for the ground wire. <<>> Golden Valley Electric Assoc. in Alaska requires #4AWG copper wire for a ground from the breaker box to earth ground rod. The same goes from the service entrance panel on the pole.
To answer this question the pump's voltage is needed.
To calculate the amperage of a 40 kVA load, you will need to know the voltage. The formula is: Amps = kVA / Volts. Assuming a standard line voltage of 120V, the amperage for a 40 kVA load would be approximately 333 amps.
A #10 copper conductor with an insulation factor of 90 degrees C is rated at 30 amps.
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
#8 copper
The recommended wire gauge for carrying 80 amps of current is typically 6 AWG (American Wire Gauge).
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).

The Full Load Amps, FLA is a rating for each winding of the motor. In this case the motor actually needs 4 amps running through it. As current needs to go somewhere (perferably not to ground) the 4 amps will circulate on you 2 Hots, the neutral isn't needed. 4A in, 4A out.
2.5 sqmm cu cable current carrying capacity is 19 amps.
