**Introduction:** The Wire Trough Size Calculator is a practical tool for electricians and engineers engaged in electrical installations. Wire troughs play a crucial role in organizing and protecting electrical wires and cables. This calculator streamlines the process of selecting the appropriate wire trough size based on the current and the number of conductors in your electrical system.

**Formula:** The formula used by the calculator takes into consideration the current (multiplied by 1.25) and adds a constant factor of 0.25. This result is then multiplied by the quantity of conductors and divided by 2, providing the recommended wire trough size in inches.

**How to Use:**

- Enter the current (A) flowing through your electrical system.
- Input the number of conductors.
- Click the “Calculate” button to obtain the recommended wire trough size in inches.

**Example:** For instance, if you have a current of 20A and 10 conductors, entering these values and clicking “Calculate” will provide you with the appropriate wire trough size for your application.
