What is the maximum number of feeders allowed from the same panelboard if each terminates in a single disconnecting means?

• A. Four
• B. Five
• C. Six
• D. Seven

Answer: (C)

The National Electrical Code (NEC) specifies that no more than six disconnects can be used for one service or feeder. This regulation is outlined in Article 225, which deals with outside feeders and branch circuits. When it comes to panelboards, a feeder that terminates in a single disconnecting means falls under the definition of a service disconnect. According to NEC guidelines, each feeder that serves a building or structure must have its own means of disconnection, but those means of disconnection should not exceed six in total for a single service location. This means that if you have one panelboard, you are allowed to connect up to six feeders to it, as each feeder presenting its own disconnect means can be consolidated within that limitation. Thus, the option indicating six is indeed the maximum number of feeders allowed from the same panelboard under the condition described.
