Cable Conductor Size Calculator

It is based on cable type insulation type and the cable installation method.

Cable conductor size calculator.

The wire size calculator will give you a very simple and quick solution to the problem of calculating the size of wires and cables for pump applications in golf courses landscape projects and agriculture. Insulation select the thermal rating of the insulation on the wire. A great tool to help electricians engineers and contractors answer the question what size conduit do i use per the nec the app will calculate the conduit fill percentages and jam probability for multiple conductors per nec guidelines. Kindly give me guidance for the calculation of cable size.

The cable sizing calculator uses the resistance r c and reactance x c values from table 9 in chapter 9 of the nec. The wire sizing calculator uses the resistance and reactance values from the pvc conduit column in chapter 9. What is the use of cable size calculator. Conductor choose the material used as a conductor in the wire.

Aluminum and flexible cables are not supported yet. Southwire s voltage drop calculator is designed for applications using awg and kcmil sizes only. The cable sizing calculator considers solid or stranded copper conductors only. The requirements of the national electrical code nec and local codes must always be followed.

Cable sizes are typically depicted as far as cross sectional territory american wire gauge awg or kcmil contingent upon the geographic district. Suppose i have 40a load and 25ka is rating and i don t have specified lentgh of cable voltage ratings but i need to give just size of cable for phase conductor and ecc is there any way to calculate it directly using some direct formula. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. To calculate ground wire size use the ground wire size calculator.

The values in table 9 is based om three single conductors in a conduit. Wire circular mils conductor. Tables 4 to 21 are based on an ambient temperature of 40 c and a ground temperature of 25 c. Common conductors are copper and aluminum.

For example 3 0 awg copper. Each has a different ampacity for a specified gauge size and these ampacities are found in nec table 310 15 b 16 for the calculations in this app. For more information on ampacity calculations please consult our technical resources. Simply enter the conduit type and size then specify your conductors.

Cable or conductor estimating is the way toward choosing suitable sizes for electrical power cable conductors. When sizing conductors calculations limits wire size to voltage drop and nec ampacity.
