The procedure (leave the formula to the electrical engineers) is to first determine the amperage required to handle the load (check code for allowed percentage of breaker amperage that can be used depending on what type load you have), determine breaker size which will tell you the minimum size wire (from code tables such as # 12 for 20 amp or # 14 for 15 amp, etc). Then determine type of insulation which depends on whether location is wet or dry, interior or exterior, and whether cable must be individual solid or stranded wires, or cables and type of conduit if any. All specified in governing code.

Could you Calculate cable size for 100 kw load?
To calculate the cable size for a 100 kW load, you would need to consider factors such as the voltage of the system, the type of cable insulation, the ambient temperature, and the installation method. The cable size is typically determined by the maximum current the cable will carry without overheating. Using the formula: Cable size (mm²) = (2 x L x I x R) / (√3 x V x cosΦ), where L is the cable length, I is the load current, R is the resistance of the cable, V is the voltage, and cosΦ is the power factor, you can calculate the appropriate cable size for the 100 kW load.

What would the cable size be for a 90 meter armoured cable with a 110 amp supply with a 330 amp start up?
To calculate voltage drop to size the wire, a voltage must be stated.
What is the cable size of 1600kVA transformer?
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.
