I need to wire up some heating elements The info I have is the heating element is 10.9 ohms. They each consume a max 16W at 12V. If I did my math right that is around 1.3 amps max for each heater. They recommend 20 gauge wire in the instructions. If I am reading the wire charts right a 20G wire can handle 1.5 amps. Am I covered enough with 20 G wire or should I go up a gauge? Things seem to be a little tight so the smaller the wire I can get away with the better.
