250 mcm wire diameter. 250 mcm is. 0 903 lbs per ft allowable ampacity. 1 520 mm 0 060 inches nylon jacket thickness. 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.

250 mcm number of strands. The sheath binds the inner wires together and its outer markings indicate the number of wires and size or gauge awg of wire within the sheathing. Circular mil means the area of a circle 1 1000 inch in diameter. The lower the gauge the thicker the wire and the greater its capacity for electrical current.

230 amps at 90 c data provided on this page is subject to change based on different manufacturers variances. We first convert from kcmil to circular mil. Wire size selection guide to use this guide place your wire or cable in the appropriate circle to determine wire outside diameter. 250 mcm wire cable.

The charts below indicate the approximate cable outside diameter or various electrical and communication cables. 0 065 inches outside diameter. Choose from our selection of 250 mcm gauge wire in a wide range of styles and sizes. 1 kcmil 1 mcm 1000 cmil 506 7 10 3 mm 2.

0 286 lbs per ft ampacity. Mcn which stands for 1 000 circular mils. 37 cross section area mm2. Typical mcm wire sizes start at 250 and go to 300 350 400 500 600 etc.

215 amps at 60ºc 255 amps at 75ºc 290 amps at 90ºc. This system uses the cross sectional area of the wire as a measurement. In stock and ready to ship. Sizing the conductors.

127 00 pvc insulation thickness conductor. The national electrical code nec recommends a maximum voltage drop of 3 percent for individual household circuits known as branch circuits this is a good goal to shoot for when sizing the conductors for an underground cable the following are the maximum lengths of cable you can use while still maintaining a 3 percent voltage drop for the given wire size awg and. Stranded bare copper bare or tinned soft annealed medium hard or hard drawn stranded bare copper. 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.

Stranded conductors offer greater flexibility than solid 250 kcmil 1 000 kcmil. Suitable for use in electrical grounding systems including counterpoise grounding and on insulators for overhead transmission and distribution applications. The color of the sheathing indicates recommended usages.
