ARTICLE 728. FIRE-RESISTIVE CABLE SYSTEMS
ARTICLE 728. FIRE-RESISTIVE CABLE SYSTEMS728.1. Scope. This new article (2014 NEC) is designed to centralize the requirements for fire-resistive cable systems, which are defined as a cable and components employed to ensure survivability of critical circuits for the prescribed period of time during a fire.728.4.
