Question:

Re: CQD answer published Friday, November 17 and 24, 2017 -Electric Rooms

(1) Since the question specifically referenced the NYC code, the answer was not 100% correct. NYC uses a modified version of the 2008 NEC. Among the modifications made are: To define a electric closet as " a room designed for or dedicated to the purpose of containing electrical distribution equipment such as vertical risers, bus ducts, transformers, or panel boards". In addition, section 800.133 has been modified to state " Communication wires inside of buildings shall not be installed in electric closets and shall comply with 800.133(A) through (D); new 800.133 (D) reads "Electric Closets. Communications equipment and cabling shall not be installed in Electric Closets. Similar modifications have been made in Article 770, 810, 820 and 830. Since the question indicated it was a IT closet and not a room which would need to comply with 645.4, I believe the answer is No, you may not locate a Electric closet and a IT closet in the same space in NYC.Thanks. Ken

(2)New York City has adopted the 2008 NEC however they have over 80 pages of amendments. The AHJ in NYC is the Electrical Division of the NYC Building Department. Requests for Code clarifications can be sent to http://www1.nyc.gov/assets/buildings/pdf/ed76.pdf.

Hey Ken and Jeff thanks for the additional information about NYC. I'm sure our readers that do work there appreciate it. Our answers are based on the NEC and this is a good reminder that local amendments or requirements can change the answer.
