Newly Revised NEC 2008 Updates Definition of Exposed Run Cable

The recently revised National Electrical Code (NEC 2008) has “adjusted” the definition for Exposed Run Cables.  It got more specific on what “Exposed” means:

NEC 2008 Article 725.154(D) hazardous (classified) location (2) and article 727.4(5) allow exposed run (ER) listed cables “to be installed exposed.  The cable shall be continuously supported and protected against physical damage using mechanical protection such as dedicated struts, angles or channels.  The cable shall be secured at intervals not exceeding 1.8 m (6 ft.).��?
