WebBranch circuit electrical wire sizes such as the #14 copper electrical wire shown just below are included in the tables on this page where we give wire sizes for circuits from 15A to 50A. Above is a close-up photo of a #14 copper wire against a millimeter scale. The divisions on the scale of my metal ruler each represent 1 mm. WebOn Average any 240 volt circuit must be a minimum of 14 gauge AWG or larger to meet code requirements. For example a basic 240 volt outlet that draws up to 15 amps would be wired with # 14/2 conductor with ground. This is a North American Standard. Sizes increase with ampreges so read on. Example:
