This report discusses two topical areas associated with localized fire barrier cladding systems for cables and cable raceways, namely, ampacity derating and cable functionality. Ampacity is defined as the electrical current carrying capacity of a particular cable in a given set of routing and environmental conditions. Ampacity derating refers to the process by which cable electrical current carrying limits are reduced in order to compensate for the thermal insulating effects of a raceway fire barrier cladding system. Cable functionality refers to the practice of assessing fire endurance ratings for a raceway fire barrier based on an assessment of the protected cables' ability to perform the intended design function before, during, and after the fire endurance exposure.
