Electrical Circuit Integrity Systems

Fire-Resistive Rated Systems & Capabilities

The National Fire Protection Association (NFPA) has fire resistive rating requirements for a 2-hour fire rating on all emergency life safety power feeds for commercial applications and a 1 or 2-hour fire rating on all emergency life safety power feeds for travel infrastructure.  Roadway tunnels (NFPA 502) require a 2-hour rating while Transit (NFPA 130) require a 1-hour rating. These requirements are set forth in the NEC.  The purpose is to provide  for survivability of critical circuits to ensure continued operation during a specified time under fire conditions.

Understanding these new requirements and codes and how they affect your project can be a daunting task.  The experienced staff of Womack Electric Supply is here to assist you, ensuring accurate specification and selection of compliant products via
our in-depth nation-wide inventories through parent company, Crescent Electric Supply, and partnerships with premiere suppliers.

Prysmian Draka’s Lifeline® RHW-2 Power Cables have been qualified and listed to the demanding requirements of UL 2196, Tests for Fire Resistive Cables.  

Lifeline® Cables are preferred over Mineral Insulated (MI) cables, concrete encasement or the construction of fire rated assemblies based on the facts that Lifeline® RHW-2 Cables are less costly, easier to install, and readily available.  Lifeline® RHW-2 Cables can be used in numerous construction applications for fire pumps, life-safety lighting, ventilation systems, elevators, and other specific emergency feeder applications to provide survivability during a fire when installed in accordance with FHIT 25C.

Atkore FRE Composites fiberglass conduit system consists of conduits, elbows, fittings, and adaptors. Using a phenolic resin-based matrix, it is designed to provide transit, utilities, and industry with a non-metallic corrosion resistant, flame resistant, low-smoke, non-toxic conduit system that is suitable for high temperature installations and in commercial construction applications.  

Atkore FRE Composites BreathSaver® XW Conduit system products meet the most stringent industry requirements for safety. 

Resolve One’s NEMA 4X fire resistive stainless-steel enclosures are the only enclosures in the country approved for use with FRE Composites BreathSaver®  conduit and Prysmian’s Lifeline® RHW-2 fire resistive cable in both vertical and horizontal conduit installations.  This 2-hour fire rated assembly (conduit/wire/enclosure) is ideal for emergency and lifeline feeds in commercial applications and buildings with elevators, fire pumps, emergency egress lighting, etc.

Resolve One offers additional pre-fabrication and custom construction solutions bridging design, application, equipment, and successful installation

Life-Safety Solutions for Transit Systems

Prysmian Draka’s Lifeline® RHW-2 Power Cables have been qualified and listed to the demanding requirements of UL 2196, Tests for Fire Resistive Cables when installed per FHIT 25C. 

Lifeline® RHW-2 Cables are preferred over Mineral Insulated (MI) cables, concrete encasement or the construction of fire rated assemblies based on the facts that Lifeline® RHW-2 Cables are less costly, easier to install, and readily available.  Lifeline® RHW-2 Cables can be used in transit system applications for tunnel lighting, life-safety lighting, and for emergency feeder applications to provide survivability during a fire.

Atkore FRE Composites fiberglass conduit system consists of conduits, elbows, fittings, and adaptors. Using a phenolic resin-based matrix, it is designed to provide transit, utilities, and industry with a non-metallic corrosion resistant, flame resistant, low-smoke, non-toxic conduit system that is suitable for high temperature installations and ideal for tunnels, subways, and other confined areas.

Atkore FRE Composites BreathSaver® XW Conduit system products meet the most stringent industry requirements for safety. 

Resolve One’s NEMA 4X fire resistive stainless- steel enclosures are the only enclosures in the country approved for use with FRE Composites phenolic conduit and Prysmian’s fire resistive cable in both vertical and horizontal conduit installations.  This 2-hour fire rated assembly (conduit/wire/enclosure) is approved for use in subway systems and roadway tunnels.  A fire resistive rating is required in transit or roadway tunnels for emergency lighting, and other emergency systems and can be used in any commercial building that has requirements per NEC Article 700, Emergency Systems.

Approved for use in the United States by the Transit Authorities of the following cities: Seattle, San Francisco, Washington DC, and Los Angeles, Massachusetts, Pennsylvania, Maryland, Virginia, and New York City Transit Authority.
