What is the current rating of 12 AWG wire?
Rating. *National Electric Code specifies that the overcurrent protection device (e.g. a fuse or breaker) must not exceed 30A for 10 AWG wire, 20A for 12 AWG wire and 15A for 14 AWG wire.
What guage of wire should I use?
thickest gauge wire available. Thicker wire will be able to handle lighter current volumes, but a thin wire will short circuit and damage the equipment if high volume current is passed through it. For a 10-15 amp breaker, a 14-gauge cable should be ideal. A 12-gauge cable is thicker and useful when
