Which labeling information should be found near a device conductor for maintenance?

Which labeling information should be found near a device conductor for maintenance?

• A. To identify color of the wire only.
• B. To identify circuit name, function, source, and destination for maintenance.
• C. To decorate the equipment.
• D. To indicate the manufacturing date.

Answer: (B)

The main idea is that labeling near a device conductor must convey enough information for maintenance to identify and isolate the correct circuit safely. The best choice includes the circuit name, what the circuit is used for (function), where it comes from (source), and where it goes (destination). This combination gives a clear map of the circuit, helping technicians locate it in the system, understand its purpose, and perform safe maintenance or lockout procedures. Color alone doesn’t provide the full context, and decoration or manufacturing date don’t aid maintenance tasks.
