Common use of Power Distribution System Grounding Clause in Contracts

Power Distribution System Grounding. The power distribution system pertains to the incoming AC service, service entrance equipment, power panels, and electrical conductors providing the power to various electrical/mechanical equipment. Grounding of the power distribution system is essential to: o protect occupants from exposure to dangerous shock voltage o provide a path for ground fault current o limit excessive voltages due to lightning or utility switching Typical grounding components for the power distribution system include: o grounding electrode at the service entrance o ground bus in the power panel o ground lugs in the other service entrance equipment such as the safety disconnect or transfer switch o third wire grounding conductor for all the electrical equipment o lightning and surge arresters.
