The terminology of “nonstray current area” is used to described an area where the electrical potential to earth and currents found on the metallic surface of underground structures are not determined by stray earth currents from DC electric railway system or a similar system having considerable amounts of stray earth currents. Stray earth currents from cathodic protection systems may or may not be considered as creating a stray current area. However, for this paper a nonstray area is an area having small currents and low potentials from one or usually several sources.
