Cable Conductor Size Calculator

Cable or conductor estimating is the way toward choosing suitable sizes for electrical power cable conductors.

Cable conductor size calculator.

The cable sizing calculator considers solid or stranded copper conductors only. The wire sizing calculator uses the resistance and reactance values from the pvc conduit column in chapter 9. Simply enter the conduit type and size then specify your conductors. Conductor choose the material used as a conductor in the wire.

When sizing conductors calculations limits wire size to voltage drop and nec ampacity. The values in table 9 is based om three single conductors in a conduit. Aluminum and flexible cables are not supported yet. The cable sizing calculator uses the resistance r c and reactance x c values from table 9 in chapter 9 of the nec.

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. The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. What is the use of cable size calculator. Tables 4 to 21 are based on an ambient temperature of 40 c and a ground temperature of 25 c.

To calculate ground wire size use the ground wire size calculator. 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. 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.

For example 3 0 awg copper. 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. Kindly give me guidance for the calculation of cable size. Insulation select the thermal rating of the insulation on the wire.

One of these wires is a ground wire which can be sized down. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. For more information on ampacity calculations please consult our technical resources. Common conductors are copper and aluminum.

The primary two metals used for electrical conductors are copper and aluminum. Wire circular mils conductor.
