Draka G30074 250 MCM 37 Stranded Lifeline Power RHW-2 RW90 Two-Hour Horizontal Vertical Fire Resistive Cable

Allowable Ampacity for Draka G30074 250 MCM 37 Stranded Lifeline Power RHW-2 RW90 Two-Hour Horizontal Vertical Fire Resistive Cable: 100 Amps

Applications:

Applications Lifeline® fire resistive cables were designed to meet and have successfully passed the two hour fire rating certification test per UL 2196, Standard for Tests for Fire Resistive Cables. Lifeline® Cables can be used in the following applications to provide survivability during a fire: - Fire Pumps - Tall Buildings - Emergency Feeder Cables - Hospitals - Ventilating Fans - Transit - Exit Lighting - Oil Refineries - Elevators - Drilling Platforms Lifeline® Cables are preferred over Mineral Insulated (MI) cables, concrete encasement or the construction of fire rated assemblies based on the facts that Lifeline® Cables are less costly, easier to install, and readily available. Fire resistive cables are required per NFPA 70, Articles 517, 695, 700, 708 and 760 as well as NFPA 72, NFPA 101, NFPA 130 and NFPA 502
