Bill:
Look here at a new 2002 NEC item in Article 80, although not mandatory, it does give valuable information.
I would recommend that a proposal be drafted to cover this in the full body of the code in Article 110:
"80.9 Application.
(A) New Installations. This Code applies to new installations. Buildings with construction permits dated after adoption of this Code shall comply with its requirements.
(B) Existing Installations. Existing electrical installations that do not comply with the provisions of this Code shall be permitted to be continued in use unless the authority having jurisdiction determines that the lack of conformity with this Code presents an imminent danger to occupants. Where changes are required for correction of hazards, a reasonable amount of time shall be given for compliance, depending on the degree of the hazard."
Frank: You agree? Any other AHJ's here? Come aboard, the posts are going to get hotter and hotter during the next few months because we only have until November to send in proposals for the 2005 NEC, and there is a deadline just look at the rear pages in the new 2002 NEC.
