The amount of current (amps) that can pass through a 1 square millimeter (sq mm) copper conductor depends on various factors, including the insulation type, temperature rating, and installation conditions. Generally, a common rule of thumb is that a 1 sq mm copper wire can safely carry about 10 to 15 amps for power transmission in typical applications. However, it's essential to consult local electrical codes and standards for specific applications to ensure safety and compliance.
