22 Awg Stranded Wire Ampacity

For allowable ampacities for fixture wire please see the national electrical code handbook.

22 awg stranded wire ampacity. Use the stayonline wire ampacity chart to look up the rated amperage of different sizes and types of cords. Because of the small gaps between the strands in a stranded wire a stranded wire with the same current carrying capacity and electrical resistance as a solid wire always have a slightly larger overall diameter. The number of strands and the awg of a strand are separated by a slash. This amp chart highlights the types of cords gauge size range number of cord coductors ampacity of current carrying conductors and much more.

For instance for no. American wire gauge conductor size table american wire gauge awg is a standardized wire gauge system for the diameters of round solid nonferrous electrically conducting wire. But the table also mentions 60 c and ampacity at 20 c insulation. Awg is sometimes also known as brown and sharpe b s wire gauge.

The larger the awg number or wire guage the smaller the physical size of the wire. Wire temperature rating ambient temperature c 200c 250c 450c ambient temperature f 41 50 0 97 0 98 0 99 106 122. For example a 22 awg 7 30 stranded wire is a 22 awg wire made from seven strands of 30 awg wire. For ambient temperatures other than 40c 104f multiply the ampacities shown above by the appropriate factor shown below.

For an m 0 awg wire use n m 1 1 m in the above formulas. We realize that the use of the legacy inch unit is not optimal included here due to the historical nature of the wire gage which should also be discontinued. Current is measured in amperes or amps. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.

The smallest awg size is 40 and the largest is 0000 4 0. My intention is to run 5v at 2a max 0 9 1 0a normal through two of them and i m trying to find out whether this cable will suffice. You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. I have a spare cable with four stranded 22 awg wires in it.

Stranded wires are specified with three numbers the overall awg size the number of strands and the awg size of a strand. Reading on wikipedia about awg i find that 22 awg has an ampacity of 7a. The awg table below is for a single solid round conductor. 0000 or 4 0 use n 3.
