Rick,

New York has adopted the 'I Codes' with their own variations (and Name) so the Residential Code is not called the IRC but it is very similar I am sure.

I am a little unclear on how this works, but it references the 1999 NEC and has about 70 pages of text, diagrams and tables on Electrical installation. It only includes rules for materials and installations most likely encountered in a one or two Family Dwelling. It seems to say that anything not included there should be subject to the applicable parts of the NEC (1999)

I have not had a chance to read or compare too much but I have not come across anything contrary to the rules in the NEC thus far. There are additional requirements that Electrical installations must conform to that are not in the NEC though.

For Example:
Rules for drilling and notching wood-framed members and Penetration of Fire-Rated Walls.
