Fire retardant vs. fire resistant cables
Fire retardant vs. fire resistant cables
(OP)
I understand that flame retardant cables don't have capability to continue in operation during a fire, while fire resistant cables can operate during fires for certain time.
most of power plants require LV & MV cables to be flame retardant where I may think that flame resistance cables may be required for vital circuits. I couldn't find any recommendation in NEC.
Any clue?

This is of course if you are anticipating a high temperature environment such a near by fire during an emergency.

Feeder-Circuit Wiring.
Feeder-circuit wiring shall meet one of the following conditions:
(2) Be a listed electrical circuit protective system with a minimum 2-hour fire rating.
ARTICLE 728: Fire Resistive Cable Systems
An information note recommends UL 2196-2006, Standard for Tests of Fire Resistive Cables.
