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.

How do you calculate cable size from the 1500 mm length?
To calculate the cable size for a 1500 mm length, you need to consider factors such as the load current, voltage drop, and the type of insulation material. First, determine the current carrying capacity required based on the load. Then, use a voltage drop formula to ensure the drop is within acceptable limits, typically around 3-5% of the supply voltage. Consult cable sizing charts or standards that provide guidance based on these parameters to select the appropriate cable size.
