## How do I calculate copper wire size?

Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. 30,000 x 1.724 x 10^-8 = 0.0005172 ohm sq.

### How do I know what gauge wire I need?

To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.

**Is 12 AWG the same as 12-gauge?**

AWG stands for American Wire Gauge. This numbering scheme was established way back in 1857, and today, remains the standard in North America that specifies the cross-sectional area of a conductor, and therefore its current carrying capability. 12 AWG, or 12 ga. They all mean the same thing and are used interchangeably.

#### What size is 12-gauge wire?

#### How to calculate cross-sectional area?

To measure cross-sectional area: Figure 5.5 A cross section view to measure stream width and depth Determine the average depth along the transect by marking off equal intervals along the string with the twist ties. Determine the width of each transect by measuring the distance from shoreline to shoreline.

**What is the cross-sectional area of a wire?**

Wire Cross-Sectional Area. The formula to find the cross-sectional area of the wire in kilo-circular mils, or kcmil, is: area (kcmil) = 1000 × diameter2. The formula to find the cross-sectional area of the wire in square millimeters is: area (mm2) = (π ÷ 4) × diameter2.

## What is the cross sectional area of a conductor?

If the cross section of the conductor is square or rectangular, the cross sectional area of the conductor can still be found by simply multiplying the width by the height. Most conductors, found in cables etc. are of course circular in cross section.

## What is the cross section of a wire?

The cross-sectional area of a wire is the size of the face of the wire if it was cut vertically perpendicular to it’s length. The cross-sectional area is independent of wire length and is typically uniform across the entire length.
