These grounding systems typically consist of ground rods or plates that are attached to the structure. Electrical fault currents and lightning strikes can be safely dissipated into the earth with the assistance of these grounding structures.
• The equipment-ground system is an essential part of the overcurrent protection system. The overcurrent protection system requires a low-impedance ground return path in order to operate promptly and properly. In 60 Hz circuits rated 40 A or less, the circuit reactance (jX) is an insignificant part of the circuit impedance.
