The New Hampshire State Building Code Review Board recently voted to adopt the 2011 National Electrical Code with one amendment. The amendment is a modification made last cycle to Section 210.5 (C) Identification for Branch Circuits. This section was modified by deleting the requirement to identify by phase each ungrounded conductor of a branch circuit, where the premises wiring system has branch circuits supplied from more than one nominal voltage system. The 2011 NEC with the single amendment is effective July 1, 2011.
