What is required for each disconnecting means to serve as service equipment?

• A. It must be manually operable only
• B. It should be power-operable but openable by hand
• C. It must include digital controls
• D. It should not exceed a certain amperage rating

Answer: (B)

For a disconnecting means to serve as service equipment, it must be readily accessible and capable of being opened by hand, even if it is also power-operable. This requirement ensures that in case of an emergency or maintenance, individuals can quickly and safely disconnect the electrical service without needing special tools or equipment. Power-operable equipment provides the convenience of remote operation but must additionally offer a manual override that allows it to be opened by hand. This dual capability enhances safety by allowing service personnel to confidently isolate electrical systems when necessary. Other choices do not fully address the necessary combination of accessibility and operational capability outlined in the National Electrical Code (NEC). For example, a requirement focused solely on being manually operable would not accommodate modern conveniences while a restriction on amperage doesn’t pertain to the operational method of the disconnecting means.
