Current ratings for wire
WebAWG sizes of copper wire, the current ratings for the wire assuming 35 EC and 10 EC rise, and feet of wire run for 5% loss at the each temperature-limited current rating. … WebAmpacity is defined by the max. current of wire for a specified temperature such as; 60, 75, 90'C which depends on the electrical/thermal insulation of the wire. The thermal resistance rises sharply with the number of strands in the core, unlike the electrical resistance, so Ampacity is maximum for a single core.
