When was 310.15(B) added to the NFPA 70 code book?
I am looking for the edition that added 310.15.B (2) Adjustment factors to the NEC.
According to Don's post it was added in 1996.
As mentioned is there any specific reason why this year is important?
I didn't take what Don said to mean iy was 1996. I think he meant that before 1996 it was listed as Note 6 not 310.15(B)(2). My impression is it is still there in 1993 esp. since jumper stated it is in 1951 NEC
IDK what the OP wants at this point.
1. When was that exact table formed and numbered that way?
or
2. When was derating for more than 3 CCCs first required?
My guess is #2

You may be right but I inferred he wanted to know when the de-rating came into effect not the specific table in that section.I thought that the OP was asking when the table was added.
