12 ga solid copper wire

Best answer


The diameter of a 12 gauge wire is2.05 millimeters. However,the diameter of a solid wire or 12 gauge bare copper wire and 12 gauge braided wire or a stranded wire is not the same. Solid wires have a smaller diameter than stranded wires. The 12 gauge bare copper wire also known as 12 gauge ground wire is the most often used grounding copper wire.
