Steps to find the cross sectional area. When large diameter wire sizes such as the widely used 250 kcmil and 350 kcmil wires are specified in kcmil the wire s diameter can be easily determined with the following formula. Second multiply the diameter by 1000 to find the area in kcmil or by 3.
Mil means 1 1000 inch. Color coded polyvinyl chloride pvc heat and moisture resistant flame retardant compound per ul 1063 and ul 8. 1000 kcmil cu 220 nl epr sim pvc jkt 15kv ct. The formula to find the cross sectional area of the wire in square millimeters is.
First find the diameter of the wire. Use the formula above to calculate the width if the awg is known. Stranded wire construction is favored instead. Circular mil means the area of a circle 1 1000 inch in diameter.
1000 mcm number of strands. Kcmil circular mils x 1000. Suitable for use in electrical grounding systems including counterpoise grounding and on insulators for overhead transmission and distribution applications. Stranded conductors offer greater flexibility than solid 250 kcmil 1 000 kcmil.
Stranded bare copper bare or tinned soft annealed medium hard or hard drawn stranded bare copper. Awg 4 3125 ln mm2 17 16 approx interpolated awg 4 3125 ln inch2 10 74 approx interpolated logical awg numbers are based on continuing the series in a logarithmic relationship to the cross sectional area of the wire. 1 kcmil 1 mcm 1000 cmil 506 7 10 3 mm 2. Area mm 2 π 4 diameter 2.
The n gauge wire s cross sercional area a n in square inches in 2 is equal to pi divided by 4 times the. The n gauge wire s cross sercional area a n in kilo circular mils kcmil is equal to 1000 times the square wire diameter d in inches in. Wire cross sectional area calculations. Solid uncoated copper conductors per astm b3 stranded uncoated copper conductors per astm b3 astm b787 and astm b8 insulation.
We first convert from kcmil to circular mil. 61 cross section area mm2.
