| - | There are many competing charts online indicating what current is allowed with various gauge wires. Maximum current ratings are to prevent the insulation on the wire from breaking down or melting due to overheating. When bundled together, the maximum rating must be reduced to account for the decrease in heat dissipation. I have listed below a conservative maximum current of the typical wire gauges, but even these maximum ratings must be reduced under various loading conditions. | + | There are many competing charts online indicating what current is allowed with various gauge wires.
