Introduction 12 AWG is the wire most people reach for the moment a project outgrows 14 AWG — a shop extension cord, a 20A kitchen circuit, a window air conditioner, a bench tool. It has a reputation as the reliable “middle” gauge: not flimsy, not overkill. That reputation is mostly deserved, but it also causes a specific kind of mistake — people keep using 12 AWG for loads that quietly outgrew it, especially once cord length or continuous draw enters the picture.
