A ___ is/are considered to be service equipment by the NEC.

• A. Service disconnecting means
• B. Panelboard
• C. Meter socket
• D. A and B

Answer: (D)

In the NEC, service equipment means the equipment that delivers power from the service point to the building and includes the devices that provide overcurrent protection for the service conductors. The parts that meet this are the service disconnecting means and the service panelboard, since each plays a direct role in controlling and protecting the service supply to the building. The meter socket, while part of the metering arrangement at the service point, is metering equipment and does not provide overcurrent protection or distribution control, so it isn’t considered service equipment. That’s why the combination of the service disconnecting means and the panelboard are regarded as service equipment.
