In a recent conversation about code changes since the 1980's, the subject of NM cable installed in conduit was brought up. Does anyone recall that at one time, NM cable installed in conduit was limited to 3 feet?

Hi Brent, and welcome to ECN.

I'm not sure if you realize that you've posted your question in the non-U.S. area of the forum.

As this appears to relate to the American NEC, I'm taking the liberty of moving the thread to the NEC & Code issues area, where you're likely to get a better response.
