Depends on the utility jurisdiction. In general, 2/2/2/4 aluminum seu will suffice for out buildings. Check with your local building code department.

A #3 copper conductor with a insulation factor of 75 or 90 degrees C is rated at 100 and 105 amps respectively.
A #4 aluminium conductor with a insulation factor of 75 or 90 degrees C is rated at 100 and 105 amps respectively.
A table in the electrical code book states what size cable or wire is allowed to carry a specific amperage. A #3 wire wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 105 amps respectively. A #2 wire wire with an insulation rating of 60, 75 or 90 degrees C is rated at 100 ,115 and 120 amps respectively.
# 2 alum.
#3 RW90 copper wire rated at 105 amps.
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps respectively.
3 AWG in copper and 2 AWG in aluminum.
To calculate the wire size, a system voltage is needed.
To answer this question the voltage and load amperage is needed.
AWG # 10 wire on 30 amp circuit.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
Normally wire is sized by the amperage of the load. In this case the wire size is calculated by knowing the length of the run to the load and the amperage of the device to be connected. By knowing the length, the wire size has to be increased to allow for voltage drop over the distance from the supply to the load.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
To calculate the wire size, a system voltage is needed.
To answer this question the voltage and load amperage is needed.

You need to know the amperage requirement of the pump and then you can calculate the wire size.
Wire size is calculated from the amount of current the load draws. More information is needed. Voltage and amperage will do fine.
The size of conductor needed will be a #14. It should be copper and have an insulation factor of 90 degrees C. The fact that it is a three phase load does not enter into the calculation of the wire size.
Circuit breakers are used to protect the conductor that is connected to it. The sizing of the conductor is based on the current of the load. As the connected load current is increased so must the wire size to accommodate that higher current. Therefore as the wire size increases so must the breaker size to accommodate the higher load current.
There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
The calculations are worked backwards from the amps used by the load of the circuit. This will be used to select the correct size of the wire. Some stipulations are added depending of the ambient temperature, length from the supply or if the load is a motor. Fusing is then dependant on the wire size that is used.
for DC load and if its copper wire the cross section of the conductor wire is generally calculated as 1/4 th of the current rating . Eg for a DC load of 16 amp the copper conductor with 4 mm square is selected.
