Comprehensive grounding and lightning protection system plan for a 5-level building (basement, ground floor, first floor, second floor, and roof). This design features foundation earth electrode system using 30×3.5mm galvanized strip connected to building’s reinforcement steel with specific clamping intervals (approximately 2m). System includes multiple lightning rods with 4m mast heights offering protection radii of 36m each, connected via 2x50mm² copper conductors. The plan incorporates test points for resistance measurement (target: <2 ohm), with specifications for additional ground rods if needed.
Key Components:
– Lightning protection system with active preventers (SE-06, SE-09, SE-12, SE-15)
– Main distribution panel (ADP) with equipotential bonding
– Floor distribution panels with dedicated grounding connections
– Elevator panel grounding integration
– 20mm diameter ground rods at strategic locations
Detailed implementation notes include foundation reinforcement connections, copper ground bar specifications (minimum 30cm for main panel), and verification requirements for site-specific earth resistivity testing (assumed at 100 ohm-m for initial calculations).
