What must each disconnect in a grouping be marked with?

• A. The name of the electrician
• B. The load served by that disconnect
• C. The maximum voltage rating
• D. The date of installation

Answer: (B)

Each disconnect in a grouping must be marked with the load served by that disconnect. This requirement ensures that anyone interacting with the disconnect can quickly identify what loads are being controlled. Such markings are crucial for safety and operational efficiency, as they inform service personnel and users about the specific circuits or equipment that the disconnect interrupts. Knowledge of which load is served helps in troubleshooting, maintenance, and operational procedures, preventing accidental disconnection of critical systems. This aligns with the NEC's emphasis on safety and clarity in electrical installations, enhancing the awareness of users regarding the purpose and function of each disconnect switch. Clear markings contribute to more effective communication about electrical systems and aids compliance with safety standards.
