Romex wire sheathing inside panel

I know a best practice is no more than 1/4" - 1" of sheathing inside the panel, but why? I thought I’ve read something about excess heat, is that true?
I know it’s sloppy and a tad “overcrowded,” but there is nothing in the NEC where this is unacceptable, correct?

Thanks in advance.




Correct as far as the sheathing but coming through a knockout without a connector needs attention. :slight_smile:

The NEC requires at least 1/4" inside the box. As long as there is at least 6" of free conductor outside the sheath it will meet code.

Thanks, Jim. Good information. :slight_smile:

Thanks Jim. Love to learn new stuff. thought it was more than that (6in.)
