2021 Code Revision and Interpretation Committee Code Interpretation (Last Updated: March 14, 2023)

In an effort to help the electrical industry make a smooth transition into the new Electrical Code and ensure the continuity in the performance of electrical work, the Department of Buildings will be posting code interpretations on its website. Listed below are new code-related questions and corresponding interpretations by the Code Committee. The users of this list should have available the 2008 edition of the NEC and the associated NYC Amendments to the 2008 NEC , as well as (Local Law 39/11) that went into effect on March 1, 2012.

All interpretations are based on the 1999 NEC and associated NY City amendments.

Whenever there are a few sections referenced, the first one is the "lead section", and the rest are secondary sections. All the secondary sections are referenced with the purpose of offering additional clarifications.
