Several months or so ago there was a thread here I think. Googling etc. to no avail,. Somebody wrote that there was someplace in the National Electrical Code that said that for sub-mains you had to lift the neutral (isolate it) in the sub-main box, and run it back to the main box. I am looking for where (article) where this is mentioned. Also I hear rumored that there is now a spec that calls out that if a line is #14, 15 amp it has to be a particular color, and also a #12, 20 amp it has to be another color. I am about to rewire the shop and would like to have it up to the code. As above article or any info??
Many thanks for the info.
