IEC 60092-307: Electrical Installations in Ships — Cable and Wiring Requirements

Marine Cables: At Sea, Cables Are Lifelines — Literally

IEC 60092-307 specifies marine electrical installation cable requirements. Marine cables are far more stringent than land-based equivalents — because fire escape at sea is essentially impossible.

Key differences: (1) Flame-retardant + fire-resistant dual certification — marine cables must pass both IEC 60332-1 (single-wire vertical flame) and IEC 60331 (circuit integrity under fire, 60–180 minutes). Land-based building cables typically only require one. (2) Low-Smoke Zero-Halogen (LSZH) is mandatory — hydrogen chloride gas released during a fire can be fatal within minutes in an enclosed ship compartment. (3) Watertight bulkhead penetrations — every bulkhead crossing requires a certified Multi-Cable Transit (MCT) seal tested per IEC 60092 fire and watertightness requirements.

Passenger ship SOLAS requirement: Emergency lighting and fire-pump cables must maintain circuit integrity for at least 60 minutes during a fire. Cable selection and installation are directly life-safety decisions.
