How much current can a 3-12 core 100 mm wire carryHow much current can a 3-12 core 100 mm wire carry?

The current-carrying capacity of a 100 mm² cable depends on several factors, including the type of insulation, installation method, and ambient temperature. Generally, for a 100 mm² copper cable, the current-carrying capacity is approximately 200 to 300 amps when installed in free air, but this can vary. It's essential to consult relevant electrical codes or standards, such as the National Electrical Code (NEC) or the International Electrotechnical Commission (IEC), for precise calculations based on specific conditions.
