The formula to calculate the wire ampacity is:
\[ I = \sqrt{\frac{T_c - T_a}{R_{dc} \cdot R_{ca}}} \]
Where:
A wire ampacity is defined as the maximum current that a conductor can carry continuously without exceeding the temperature rating.
Let's assume the following values:
Using the formula:
\[ I = \sqrt{\frac{90 - 30}{0.5 \cdot 0.1}} = \sqrt{\frac{60}{0.05}} = \sqrt{1200} \approx 34.64 \text{ kiloamps} \]
The wire ampacity would be approximately 34.64 kiloamps.
Let's assume the following values:
Using the formula:
\[ I = \sqrt{\frac{75 - 25}{0.3 \cdot 0.2}} = \sqrt{\frac{50}{0.06}} = \sqrt{833.33} \approx 28.87 \text{ kiloamps} \]
The wire ampacity would be approximately 28.87 kiloamps.
