This code outlines fire safety requirements for electrical installations in buildings. It provides guidelines on the safe installation of substations, switchgear, wiring, cables, and emergency power systems to prevent electrical fires and restrict their spread.
Specifies requirements for fire safety concerning electrical installations in buildings, applicable to HVAC electrical components.
Quick Reference Values
Fire resistance of electrical shaft doors2 hours
Minimum emergency power supply duration90 minutes
Max earth leakage current for fire protection tripping (RCCB)300 mA
Clearance of oil-filled transformer (>2000L) from building without fire wall15 m
Practical Notes
Always seal electrical shafts at every floor level with approved fire-stopping materials to prevent the chimney effect during a fire.
FRLS (Fire Retardant Low Smoke) or LSZH (Low Smoke Zero Halogen) cables are mandatory in public buildings, basements, and escape routes.
Ensure adequate oil containment (soak pits) and fire separation (blast walls) for indoor and outdoor oil-filled transformers.
