How much romex sheath to expose in a panel pass through?

I have romex passing through one panel into another panel (they are connected through a metal nipple) where it will terminate at a breaker in the second panel. I believe at least 1/4" of sheath has to be exposed and there is no maximum but where should I strip the sheeting? Where it enters the pass-through panel or as it enters the destination panel?

Hi, I would strip it where it enters the first panel and run the individual conductors into the 2nd panel.

Since the first panel is being used only as a raceway the sheathing should not be removed until it enters the second panel where it's being terminated. By leaving the sheathing on in the first panel makes it clearly visible it is a cable that is passing through. Also the NEC requires 1/4" of the sheathing to enter the device box which in your case is the second panel.
