Introduction: The Wiring Size Calculator is a practical tool for electricians and individuals involved in electrical installations. Selecting the correct wiring size is essential to ensure that the electrical circuits can safely carry the required current without issues such as overheating. This calculator simplifies the process of determining the appropriate wiring size based on the current flowing through the circuit.
Formula: The formula used by the calculator multiplies the current by a safety factor of 1.25 and then divides the result by 2. This calculation provides the recommended wiring size in square millimeters (mm²), taking into account safety margins for optimal performance.
How to Use:
- Enter the current (A) flowing through your electrical circuit.
- Click the “Calculate” button to obtain the recommended wiring size in square millimeters (mm²).
Example: For example, if you have a circuit with a current of 20A, entering this value and clicking “Calculate” will provide you with the appropriate wiring size for your application.
