Suitable for use in electrical grounding systems including counterpoise grounding and on insulators for overhead transmission and distribution applications. 250 mcm number of strands. 250 mcm is. 1 520 mm 0 060 inches nylon jacket thickness.

This system uses the cross sectional area of the wire as a measurement. Choose from our selection of 250 mcm gauge wire in a wide range of styles and sizes. Circular mil means the area of a circle 1 1000 inch in diameter. In stock and ready to ship.

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. 0 200 mm 0 008 inches outside diameter. 127 00 pvc insulation thickness conductor. Mcn which stands for 1 000 circular mils.

250 mcm wire cable. 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. The color of the sheathing indicates recommended usages. 17 23 mm 0 678 inches weight.

Stranded bare copper bare or tinned soft annealed medium hard or hard drawn stranded bare copper. The charts below indicate the approximate cable outside diameter or various electrical and communication cables. 0 065 inches outside diameter. We first convert from kcmil to circular mil.

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. Typical mcm wire sizes start at 250 and go to 300 350 400 500 600 etc.
