What are fire resistive or fire rated cables.
Ul fire resistive cable.
Fire resistant cables are often used to maintain circuit integrity of those vital life safety systems such as fire alarm and suppression services.

Fire resistance rated designs are used to achieve code compliant installations where the building codes require hourly rated designs.
August 29 2017 ansi approved.
First a concern was brought to ul s attention that when fire resistive cables were installed in conduit with a zinc coating the circuit integrity was compromised by a reaction of the zinc with the copper conductors lowering.
2 with ahj approval a larger size conduit may be required if an egc is used.
Ul standard for fire retardant cable.
The definition of a fire resistive or fire rated cable is a cable that will continue to operate in the presence of a fire.
They have passed rigorous ul fire resistive testing maintaining a constant signal connection for two hours at 1850 f.
We test assemblies to international standards establishing an hourly rating to provide evidence of compliance to code requirements.
