Note that cable operating temperature is not being considered and cable short-circuit performance is also ignored and y ou should use our Cable Pro Web по ссылке for the most accuracy. Please enter the parameters below and 3 phase feeder size schedule free Calculate. The minimum active cable size is provided which meets the current-carrying capacity and the maximum voltage 3 phase feeder size schedule free requirements. Note that a cable size larger than this minimum is also acceptable and may be more economical in terms of electrical losses over its lifetime.

Voltage V — This is the voltage of the supply which is V for single phase and V for 3 phase supply by default. Phase 3 phase feeder size schedule free Select the phase arrangement as either single phase, three phase, two phase or DC. Load — Specify a value for the load whether it be in Amps, kilowatts, kVA or horsepower.
Note for a three phase load this should be the current of the highest loaded phase. Refer to our article Voltage drop limits for 3 phase feeder size schedule free voltage installations. Power factor — enter the load power factor assumed lagging.
The voltage drop calculation in this calculator considers power factor which is more accurate. Cable length m перейти this is the length of the cable from the point of supply to the load. Conductor — select the conductor material which affects current-carrying capacity and the voltage drop due to different resistance values.
Insulation — the insulation type which affects the maximum allowable operating temperature and hence the current rating. Cables with higher allowable temperature which depends on the insulation type will have a higher current rating.
Installation — select the installation method of the cable circuit which matches your installation. Note that if the installation method changes along its route then choose the worst case resulting по этому сообщению the lowest possible current rating along its entire length. Results explained.
