Cable Sizing & Selection. Overview. One of the most important aspects of designing and building any part of a vehicle electrical system is determining the correct size and type of cable to use for each circuit. Too small a cable size and you'll run the risk of generating heat in the cable; too large and you'll be wasting money on copper you don't need.

Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing.

Total electrical capacity of an electrical service is measured in amperage (amps). In very old homes with knob-and-tube wiring and screw-in fuses, you may find the original electrical service delivers 30 amps.Slightly newer homes (built before 1960) may have 60-amp service. In many homes built after 1960 (or upgraded older homes), 100 amps is the standard service size.

The current ratings are selected from Tables 4 to 21 in AS/NZS 3008. It is based on cable type, insulation type and the cable installation method. Tables 4 to 21 are based on an ambient temperature of 40°C and a ground temperature of 25°C. The cable sizing calculator …

Our calculator now lists different cable types, so by scrolling down the list you are able to see how different cable types may have different sizes for the same set of ...

Here voltage drop for 70 Sq.mm Cable (5.8 %) is higher than define voltage drop (5%) so either select higher size of cable or increase no of cable runs. If we select 2 runs, than voltage drop is 2.8% which is within limit (5%) but to use 2 runs of cable of 70 Sq.mm cable is not economical, so it's necessary to use next higher size of cable.
