Multi-Floor lighting Plan with NHXMH/N2XH Cable Distribution System

Comprehensive Building Electrical Lighting System

This drawing depicts a complete lighting plan for a 5-level building (basement, ground, 1st, 2nd, and roof levels) with circuit distribution details. The lighting system features integrated normal and emergency lighting circuits with distinct cabling specifications throughout all floors.

The electrical distribution network is organized through multiple distribution panels, with each floor having its own dedicated panel, identified as BK-DP (basement), ZK-DP (ground floor), 1K-DP (1st floor), 2K-DP (2nd floor), and ÇK-DP (roof floor). Each distribution panel feeds multiple lighting circuits using 3×2.5mm² NHXMH cables for normal lighting and 3×1.5mm² N2XH FE180/PH90 fire-resistant cables for emergency lighting.

Lighting Fixtures and Components:
– 60×60cm LED modular ceiling fixtures (both with and without emergency kits)
– 10W LED recessed spotlights (both standard and emergency versions)
– Linear LED fixtures with 14.4W/m power density
– 18W surface-mounted LED fixtures
– Explosion-proof fixtures for specialized areas
– Emergency exit signs with 3-hour battery backup

Technical Details:
– System designed to comply with national electrical codes as noted in project notes
– Room-specific circuit allocation with annotated cable sizes
– Motion sensors (360° ceiling-mounted type) in appropriate locations
– Integrated switching arrangements using standard and commutator switches
– Total building footprint: approximately 550-565m² per typical floor

The drawing includes comprehensive installation notes specifying conductor routing methods (under-plaster, above suspended ceiling), junction box requirements, and mounting heights for switches (110cm) and outlets (40cm).
