The formula to calculate the percent fill of a conduit is:
\[ P = \left( \frac{V_f}{V_i} \right) \times 100 \]
Where:
Conduit percent fill is a measure of how much of the internal volume of a conduit is occupied by cables or wires. It is expressed as a percentage and is used to ensure that the conduit is not overfilled, which can lead to overheating and damage to the cables. Proper calculation of conduit fill is essential for maintaining the safety and efficiency of electrical installations.
Example:
Calculation:
\[ P = \left( \frac{50}{100} \right) \times 100 = 50\% \]
