A gauge for measuring | sending the diameter of round wire according to an | and rece at the r arbitrary standard. The American or charges Brown & Sharpe (B. & S.) gauge is used | strument almost exclusively in America in electrical | ing mast of waves work. Other well-known gauges are the Roebling gauge used extensively for iron and steel wire, and the Birmingham gauge used largely in Great Britain and also in America for wires other than those designed for electrical conductors. The diameters of wires on the B. & S. gauge are obtained from the geometric series in which No. 0000 equals 0.46 inch and No. 36 equals.005 inch. 2. A device for determining the gauge of a wire. It is often in the form of a dise or broad flat ring of sheet steel with notches in the circumference corresponding to the numbers and sizes fixed by that gauge. A more accurate gauge is in the form of a vernier caliper measuring the wire in mils or thousandths of an inch.
