A visual representation depicts the components and connections where overhead power lines transition to a building’s electrical system. This typically includes the mast, insulator, weatherhead cap, entrance cable, and conduit. An example would show these elements and how they fit together, clarifying the path electricity takes into a structure.
This visual guide is critical for safe and compliant electrical installations. It ensures proper grounding and weatherproofing, protecting the building and its occupants from electrical hazards. Historically, these visualizations have evolved alongside electrical codes and safety standards, reflecting advancements in materials and installation techniques. Their use contributes significantly to standardized practices within the electrical industry.
