The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
First, you will need the mini light bulb Second, you will need the crank Third, you'll need the metal lid Fourth, you will need the generator thingy Fifth, you will need a small PVC pipe Sixth, you will need a red and blue wire Last, you will need a crank Mini light bulb connected to the small PVC pipe, small PVC pipe connected to the rectangle plank, rectangle plank connected to a metal lid, metal lid connected to a crank, and crank connected to a blue and red wire. You will put the glue on the generator thingy. Put on the red wire connects to the blue wire And there! A generator
10-32 unf-2a <<>> The wire size does not need to be calculated. Use a wire terminal end that crimps to the wire. These terminal end come in various wire sizes and bolt hole sizes. Pick the correct end for the wire size you are using and then in that wire size range, pick the correct bolt hole size that fits the bolt.
You need to mention the current or connected load to define the size of the wire
You need to know the amperage requirement of the pump and then you can calculate the wire size.
For a 200amp service you need number 4 copper
For a typical use it would be 1/0 (one ought) wire in copper.
No, you can use #4 bare copper ground wire.
A #6 copper ground conductor would be needed.

Use AWG #6 wire.
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
A 200 amp service panel with a 60 amp sub-panel.

You will need to use #8 wire.
Wire size is based on the amperage of the connected load. Without that amperage an answer can not be given.
