Equipment or Building?

摘要

At some properties, a single electric utility service supplies multiple buildings or structures. The service could directly supply one of the buildings, and feeders or branch circuits supply other buildings from that service equipment. Another arrangement might be that the utility service is freestanding, such as on a pole or pad-mounted, and feeders or branch circuits supply all buildings or structures. Specific grounding and bonding rules apply to separate buildings or structures supplied by feeders or branch circuits. The requirements are located in Part Ⅲ of National Electrical Code (NEC) Article 250 (specifically, 250.32).
