WebGrounding is the electrical system’s connection to the ground itself. Article 100 of the NEC defines ground as “the earth.”. Section 250.4 (A) (1) states that grounded electrical systems “shall be connected to earth in a manner that will limit the voltage imposed by lightning, line surges, or unintentional contact with higher-voltage ... WebExtra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage. [citation needed] Extra ground connections on a neutral conductor may bypass the protection provided by a ground-fault circuit interrupter. Signal circuits that ...
