A 1984 NEC handbook commentary says Section 230.40 is new (in 1984). I am trying to find the intent behind the original Exception 1 to 230.40. Does anyone have any type of analysis book, a copy of the proposals, or panel comments?

Charlie,
Was it the same section in the 84 code? I have the 83 TCR and the proposals for 230.40 have to to with bare or covered aluminum service entrance conductors.
Don

I thought so Don, I will have to check tomorrow afternoon when I get back in the office.

Charlie,
In the 81 code 230.40 was "Insulation of Service-Entrance Conductors" and in the 87 code it was "Number of Service-Entrance Conductor Sets". (I couldn't find my 84 book)
Don

Don, the 1981 Code has 230-40 but it is Insulation of Service-Entrance Conductors. In the 1984 Code, the proposal would be addressed as 230-XX (NEW) in the TCR. After it was accepted, it was inserted ahead of Insulation of Service-Entrance Conductors and became Number of Service-Entrance Conductor Sets.

Don Ganiere was able to provide copies of the pages from the TCR and TCD the grew into the 1984 Edition of the NEC.

Thank you Don,
Charlie
