A Keys, welcome to the forum.

Your text is word-for-word identical to NEC-2005, as far as I can tell. What are you trying to change?

320.30 (C) Horizontal runs of Type AC cable installed in wooden or metal framing members or similar supporting means shall be considered supported where such support does not exceed 1.4-m (4?-ft) intervals.

330.30 (C) Horizontal runs of Type MC cable installed in wooden or metal framing members or similar supporting means shall be considered supported and SECURED where such support does not exceed 1.8-m (6-ft) intervals.

Comparing the two sections we see the word secured in 330 that is missing in 320. A cable that is lying in a bored hole is not secured only supported.

Good eye A Keys

Re: 330.30(C)

The question stands. What are you trying to change? 330, or 320?
