1. Actual Load = Voltage x Current x Power Factor
2. Cable size selection depends on many factors
- Length of the cable, Load, Maximum permissible voltage drop, Voltage drop/amphere/meter
- First of all find the Voltage Drop of cable with this equation
- Voltage Drop= (Current x Length of cable x Voltage drop/amphere/meter)/ ( x No. of runs of cable)
- Then check the voltage drop within the limit of maximum permissible voltage drop.
- If not, increase the selected cable size, Please note Voltage drop/amphere/meter for each cable different.
