125 Amp Panel Wire Size

Three pumps of a pump station 30 10 and 1 horsepower are connected to the power source of 460 volts 3 phase.
125 amp panel wire size. How to wire a 125 amp service step 1 firstly ensure that the power is completely off for safety reasons by disconnecting the power leads from the meter. I understand i could use a 125 amp breaker but i do not need the additional amperage. V1 v2 load in amps calculate cable selection copper only up to 25mm above this cable reactance must be considered.
I assume i need to run 4 wires 2 hot 1 neutral and 1 ground. Enter your proposed cable size type of insulation voltage ambient temp 30 is norm your cable length and circuit load in amps. I w e 70000 240 291 67 amps.
The run is no more than 100ft. When more than one motor is used the current of the largest load must be multiplied by 1 25 plus the sum of the rest. 291 67 x 125 364 6.
What size wire should i use in aluminum as it is cheaper. 291 67 x 125 364 6. The wire size according to code has to be up sized to 125.
The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. I am installing a 125 amp load center in my house to service an addition. 500mcm copperwire with an insulation factor of 75 and 90 degrees c is rated at380 and 395 amps respectively.
From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. The wire size according to codehas to be up sized to 125.
