Residential Electrical Plan with Unifilar Diagrams and Load Calculations

This comprehensive electrical plan depicts a three-story residential building with detailed electrical distribution systems. The drawing includes floor plans (first, second/third floors, and roof) with electrical device placements at scale 1:50. Key features include complete unifilar diagrams for three distribution panels (TD-1, TD-2, TD-S), showing circuit breaker ratings, conductor specifications, and circuit allocations. The electrical system utilizes 220V service with PVC conduit installations. Detailed load calculations show a maximum demand of 13,334.70W for TD-1 and similar calculations for other panels, with proper diversity factors applied. The drawing includes complete legends for electrical symbols, grounding details showing 16mm copper electrode installation, and technical specifications for materials (PVC-SAP conduits, TW/THW insulated copper conductors). Lighting and power outlets are strategically placed throughout living spaces including kitchen, bathrooms, bedrooms, dining areas, and terraces. Special circuits are dedicated for high-consumption appliances like electric cooking equipment (8000W), water heater (1500W), and washer/dryer (3000W).
