2 0 Wire Size Chart

American wire gauge size calculator and chart.

2 0 wire size chart. 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. Wire size ampacity charts. 60 c 140 f nm b uf b. For application of this section the main.

Current is measured in amperes or amps. 60 c 75 c 90 c 60 c 75 c 90 c 1 2 3 4 1 1 1 4 1 1 2 2 2 1 2 3 3 1 2 4 14. Awg wire sizes see chart below awg. Common sizes include 14 12 10 8 6 and 2 gauge wire.

The n gauge wire diameter d n in inches in is equal to 0 005in times 92 raised to the power of 36 minus gauge number n divided by 39. Amperage is a measure of the electrical current flowing through a circuit. D n in 0 005 in 92 36 n 39. American wire gauge awg is a standardized wire gauge system for the diameters of round solid nonferrous electrically conducting wire.

Gauges you use 1 2 3 which makes more sense mathematically than double nought. The smallest awg size is 40 and the largest is 0000 4 0. 90 c 194 f thwn 2 thhn xhhw 2 use 2. The larger the awg number or wire guage the smaller the physical size of the wire.

The calculator allows entry of a voltage drop but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with nec article 210 19 fpn no. 120 240 volt 3 wire single phase service entrance conductors service lateral conductors and feeder conductors that serve as the main power feeder to a dwelling unit and are installed in raceway or cable with or without an equipment grounding conductor. Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter. Awg general rules of thumb for every 6 gauge decrease the.

In the american wire gauge awg system wire size diameters can be calculated by applying the formula d awg 005 92 36 awg 39 inch. Wire is sized by the american wire gauge awg system. Wire gauge calculations wire diameter calculations. Size copper aluminum diameter wires in conduit.

You must use the correct size wire for the amperage requirement of the circuit to prevent the wire from over heating. For the 00 000 0000 etc.
