Electrical Circuit Protective Systems
This category covers electrical circuit protective systems consisting of components and materials intended for installation as protection for electrical wiring systems. The systems are investigated with respect to the disruption of electrical circuit integrity during a period of fire exposure.
Performance criteria for systems utilizing fire resistive cables (FHJR) are investigated using ANSI/UL 2196, "Tests for Fire Resistive Cables." The requirements used to investigate systems incorporating cable protected with electrical circuit protective materials are contained in UL Subject 1724, "Outline of Investigation for Fire Tests for Electrical Circuit Protective Systems."
This product category covers systems that are similar to those covered under Thermal Barrier Systems (XCLF).
