This standard describes requirements for numbering and labeling of real property electrical distribution equipment, circuits, and site lighting at Lawrence Livermore National Laboratory. Understanding the numbering system for electrical wires is a critical part of being able to understand the symbols and diagrams used in electrical designs. Everything is arranged according to functions, so each function has a unique name, i. "=K1", "=K2", "=G1", etc. That means that every single wire can be identified in. Purpose – This Article is about all electrical equipment numbering system, Electrical Panel Numbering System, Electrical Wire Numbering System, Electrical Relay Numbering System, Electrical Drawing Numbering System, Electrical Schematic Numbering System, Electrical Cable Numbering Systems.
