Wire Gauge Thickness Calculator

The max length indicates the maximum length of wire of that gauge that can be use at the given values you entered.

Wire gauge thickness calculator.

If the wire gauge is ok to use it will have a check mark on the same line. D n in 0 005 in 92 36 n 39. Second multiply the diameter by 1000 to find the area in kcmil or by 3 1415 4 to calculate square millimeters. Voltage loss or drops through incorrectly sized cables are one of the most common reasons for low voltage 12v.

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. This website provides a wire size calculator voltage drop calculator wire ampacity charts and more. First find the diameter of the wire. This online cable size calculator tool makes it easy to establish the correct size of cables for any dc power system.

Average wire gauge charts for copper sheet wire. Wire gauge diameter area and resistance chart. Wire gauge calculations wire diameter calculations. 4 the nec allows a maximum of a 3 voltage drop on the main branch of a circuit at the farthest outlet of power and 5 total to both feeders and branch.

For example to see the effective gauge of a cable made from 10 20 gauge wires select 20 gauge from the drop list then type 10 into the number of wires field and press the tab key. Cable sizes are particularly important for low voltage battery cables solar panels wind turbines and load cables. For full table with stainless steel aluminum strip and tubing rotate the screen. Typically most automotive systems run at 13 8v but you can select 6 12 13 8 default or 24 volts.

The higher the gauge number the thinner the metal. This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps voltage distance and load. Wire gauge is a measure for the size of a wire either in diameter or in cross sectional area. This chart shows approximate gauge thickness for metal to give a relative idea of different gauges.

Wire size calculation selection of the appropriate line when calculating the cross section according to the above formula the result is a value in square millimeters mm 2. Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing. The combination is equivalent to a single 10 awg gage. Use the formula above to calculate the width if the awg is known.

The n gauge wire diameter d n in millimeters mm is equal to 0 127mm times 92 raised to the power of 36 minus gauge. American wire gauge size calculator and chart. This will rarely fit exactly on a commercial cross section.
