How should branch circuits be labeled according to the NEC?

Branch circuits must be clearly identified in the service panel to indicate their use, as this practice enhances safety and facilitates maintenance. Proper labeling allows anyone accessing the panel to quickly understand which circuits control specific areas or appliances, thereby reducing the risk of accidents and streamlining troubleshooting. The NEC emphasizes the importance of clear identification to ensure that anyone working on the electrical system can do so with an understanding of the system’s layout and functionality.

Labeling provides an essential reference for electricians and other professionals who may need to perform work on the electrical system while ensuring that they can safely isolate circuits without confusion. This practice contributes to the overall safety and reliability of electrical installations.
