When a conductor is not visible on a terminal, what identification is required?

When a conductor is not visible on a terminal, it is essential to provide clear identification to ensure proper understanding and safety in electrical systems. The requirement to include the word "White" or "W" next to the conductor hole serves to specify the function or type of the conductor, particularly in the context of wiring systems.

In electrical wiring, color codes are standardized to indicate different functions: for example, a white conductor typically represents a neutral wire. By providing this identification next to the terminal, it conveys critical information that aids in future maintenance or troubleshooting, ensuring that anyone interacting with the wiring can quickly understand its purpose without relying on assumptions.

This practice not only aligns with safety standards but also promotes clarity and prevents errors during installation, inspections, or repairs. In contrast, options that suggest using generic labels, stickers, or stating that no identification is necessary do not provide the same level of immediate recognition and understanding, which is vital in managing electrical systems efficiently and safely.
