Welcome to this forum, I hope that it is as positve an experiance for you as it is for me.
You didn't tell us what type of cable you're running. The 300 volt rating doesn't mean a thing in this case. See 411-4. If your cable is not one of the wiring methods allowed in Chapter 3, you're out of luck. I've had plenty of salesmen at the home center (or cabinet mfg) claim that zip cord is OK, they're dead wrong.
Your inspector was remiss in his duties, he should have given you the code section that covered this violation.
