The cable and wire sizing calculator calculates the required cable or wire size based on current rating and voltage drop according to the American National Electricity Code NEC This method calculates the impedance for the worse case icda factor, i.

Specify the voltage and select the phase arrangement: Currently supports AC only. Load kW, kVA, A, hp: The maximum allowable voltage drop.

The estimated cable or wire length in meters of feet Short circuit current and time kA, ms: The short circuit current and clearing time for the protection device.

On low voltage circuits the let-through current is typically used, i. On high voltage circuits the prospective fault current is typically p-32-32 i. This is so that the cable can also handle a fault if the primary protection fails. Furthermore, high voltage circuit breakers typically do not limit the fault current. The number of current carrying conductors in a raceway, cable or buried directly. No more than three p-32-32 allowed without applying a derating factor.

Insulated Cable Engineers Association (ICEA) Standards and

Ignore the neutral and earth conductor in three phase cables. The type of insulation. The important part is to select the correct temperature rating.

Number of parallel conductors: Typically only one cable. More than one cable may be selected for high load scenarios.

This will affect the derating of the cables. This ica not considered in this version of the calculator. How the conductors are in installed. The current rating is selected from Table The current rating is based on the insulation type. The current rating is also based on installation method. The wire sizing calculator considers copper conductors only.

For higher temperatures, a derating will have to be applied according to NEC. It is assumed that there is only one three current carrying conductors in a raceway, cable or buried.

And that the raceways, cables and buried conductors are spaced according to NEC to prenet derating.

To apply a manual derating, divide the load by the derating factor from NEC, and enter the new load value in the calculator. The single phase AC voltage drop is calculated as: The three phase AC voltage drop is calculated as: The impedance is calculated as: The values in Table 9 is based om three single conductors in a conduit.

The wire sizing calculator uses the resistance and reactance values from the PVC conduit column in chapter 9. The short circuit capacity is calculated as: A is the conductor area in circular mils.
