    • According to 2 sources
    Since the size of 18 gauge wire is only around 0.0403 inches in diameter, the US National Electric Code or NEC only rated it up to 14 amps in a raceway or 18 amps in free air at 90 degrees Celsius; these levels of power should prevent the cable from getting too hot. If the wire gets too hot, it may damage the insulation and create a fire hazard.
