Electrical Single Line Diagram AutoCAD DWG with Panels and Load Data

This AutoCAD DWG file presents a complete set of electrical single-line diagrams prepared for large institutional and commercial buildings. The drawings illustrate detailed power distribution architecture, including main incoming supply, transformers, LT panels, sub distribution boards, MCC panels, and feeder connections. Load flow paths are clearly shown with circuit numbering, breaker ratings, cable sizing, and protection devices. The layouts include segregation of critical and non-critical loads, earthing connections, and coordination between substations, utility rooms, and building service areas. Voltage levels, panel schedules, and feeder routes are represented to support accurate electrical planning and execution.

The drawing set further covers electrical distribution for multiple building zones such as laboratories, office blocks, service areas, parking zones, and specialized functional spaces. Each single line diagram shows connected loads, demand factors, diversity considerations, and panel capacities to ensure system reliability and safety. Measurement details, schematic alignment, and clear annotations make this DWG suitable for coordination with architectural, structural, and MEP drawings. These electrical AutoCAD drawings are ideal for architects, electrical engineers, civil engineers, builders, and consultants who require precise documentation for approvals, construction, and system integration using AutoCAD, Revit, 3D Max, and SketchUp compatible workflows.
