How do you determine wire gauge size?
To calculate the gauge of stranded wire, you’ll need to double the diameter. So, if you’ve measured a wire’s diameter to be 0.005 inches (0.127 mm), multiply this value by itself. The result will be 0.000025 in (0.000635 mm). Multiply the result by the number of strands in the wire.
How do you size copper wire?
Copper Wire Gauges
Derived from the American Wire Gauge (AWG) standardized measurement system, the term gauge indicates the overall thickness of a given wire. In general, the smaller the gauge number, the larger the size of the wire itself.
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.
