What is a requirement for labeling service conductors?

Labeling service conductors is essential for ensuring safety and compliance with electrical codes. The requirement for labeling applies specifically to any services that are less than the rated protection of the conductors. This means that if the conductors have a certain amperage rating, labeling is necessary to indicate their capacity and ensure that they are not overloaded or misused.

Labeling helps in identifying and communicating the maximum permissible load, which is crucial for maintenance, repair, and safety checks. Proper labeling ensures that individuals working on or near these conductors are aware of their limitations and can make informed decisions to prevent potential hazards such as overheating or electrical fires.

In contrast, labeling is not limited to commercial services, nor does it apply only to services over 400 amperes or those with significantly high volt ratings. The requirement is broader and applies to all situations where the service may not meet the rated protection, prioritizing safety and correct usage regardless of the setting.
