neutral wire - The conductor of a polyphase circuit or a single-phase three wire circuit that is intended to have a ground potential. The potential difference between the neutral and each of the other conductors are approximately equal in magnitude and equally spaced in phase. wire gauge - American wire gauge (AWG) is a system of numerical designations of wire diameters. wire wrapping - Method of making a connection by wrapping wire around a rectangular pin. wire - Single solid or stranded group of conductors having a low resistance to current flow. Used to make connections between circuits or points in a circuit. wireless - Term describing radio communication that requires no wired between two communicating points.
