The National Electrical Manufacturers Association (NEMA) has published RV 2-2011 Application and Installation Guidelines for Nonmetallic-Sheathed Cable and Underground Feeder and Branch Circuit Cable. Last revised in 2008, the standard is produced by NEMA’s Building Wire and Cable Group and Dues Center.
RV 2 provides installers and code enforcement officials with information on the proper application of nonmetallic-sheathed cable listed according to UL 719 and underground feeder and branch circuit cable listed according to UL 493. “This publication covers critical installation issues, such as proper fitting assembly and stapling techniques, that maintain the mechanical integrity of the nonmetallic-sheathed cable system,” explained NEMA.
The revision reflects changes to the National Electrical Code that took effect January 1, 2011, and the updated description of category PWVX as it appears in the 2010 UL White Book.
