The only purpose of earth conductors is to operate the circuit protective devices in the event of a fault, thereby protecting lives and property.

The purpose of bonding all metal parts of the building together is to reduce the voltage potential between parts.If all parts are grounded to a common point, the voltages induced by a lightning strike are safely shunted to ground.This also has the benefit of reducing noise that can be induced by structural parts at different potentials.

The ground also serves a critical function in the event of a current fault to ground by providing a low resistance path to trip fault detection equipment or circuit breakers.

All grounds should terminate at a common point.
