Hi guys, I live in New York city and we are still on the 2008 NEC, with a few amendments. Eventually, we will adopt the 2011 NEC and apply our amendments to it. I was reading in this month's EC&M magazine, and I came across Mike Holt's article on code basics. The article mentions a clarificaton as it pertains to spare conductors in a raceway and the ampacity adjustment procedures that was made in the 2011 NEC. I believe that the 2011 NEC stated that spare conductors are not included whenever you have to make ampacity adjustments. I know that there was some confusion, and that was cleared up in the 2014 NEC, but I can not ignore the inevitable when it comes time for the city to adopt the 2011 NEC. Can anyone point out this note or article that pertains to spare conductors not be counted for ampacity adjustment calculations? I'm looking at the 2011 NEC and not 2014. Thanks.
