Requirements for Circuit Identification Signs in Distribution Boxes
22 (A): This section specifies the labeling requirements for disconnects and circuits. Essentially, every circuit in an electrical panel must be clearly identified so that users know which circuit controls which device or area. You need to label every circuit breaker clearly and accurately to meet National Electrical Code (NEC). This standard describes requirements for numbering and labeling of real property electrical distribution equipment, circuits, and site lighting at Lawrence Livermore National Laboratory. This is an internal LLNL standard meant to guide the design of new facilities, facility modifications, and. Learn what the NEC requires for electrical panel labels, from circuit directories to arc flash warnings and solar system markings.
