Most Common Installation Deficiencies - 2002

The Board welcomes any input from instructors, inspectors, licensees and other concerned parties relative to this list or any other items of concern. The Board would like to remind all concerned parties that the 2002 NEC becomes effective July 1, 2002 as part of the Board's administrative rules. Some local municipalities may adopt the 2002 NEC at an earlier date therefore, it is advisable to check with the local authority before starting an installation. However, no matter what edition of the NEC the local municipality is under installations in the State of New Hampshire must be performed to the current edition of the NEC as adopted by the Electricians' Board.
