How to calculate heat in wires. | All About Circuits

17.03.2015· A #14 wire has only about 2.4 square inches so the estimate of the wattage that way would be around in the neighborhood of 200 watts. I am not sure i can trust that estimate though, and the wire has no coating. That estimate tells us that three feet of #14 wire can take over 160 amps without melting. That''s got to easily be welding current.
