Earth Grid —A system of grounding electrodes consisting of inter-connected connectors buried in the earth to provide a common ground for electrical devices and metallic structures.
NOTE—The term ‘earth grid’ does not include ‘earth mat’.
Earth Mat—A grounding system formed by a grid of horizontally buried conductors and which serves to dissipate the earth fault current to earth and also as an equipotential bonding conductor system.
