9 Recommended Practices for Grounding
During fault conditions, low impedance results in high fault current flow, causing overcurrent protective devices to operate, clearing the fault quickly and safely. The grounding system also allows transients such as lightning to be safely diverted to earth. Bonding is the intentional joining of normally non-current-carrying metallic components to form an …
