Abstract :
Recent changes to the National Electrical Code (NEC) and to Underwriters Laboratories (UL) standards, coupled with technological changes, present new opportunities for ease of installation, labor saving and reliability of power cables and conduits. New techniques for factory sealing in Division 1 and 2 are explained, as are various methods to achieve 40% conduit fill for sealing fittings. New sealing methods for multiconductor cables in conduits are covered as well as new requirements for metal-clad cable seals for Division 1
