He said to use tie wire and drill a hole and tie it down to the stud. Is there any code that says you have to do this? Thank you for your help. P.S. When I say running inside studs I mean horizontally, through the existing holes.
Tell the inspector there is a difference between being supported and being secured. Drilled holes or metal stud holes are supporting the wire.....

I understand that 330.30(C) says that. However, under 330.30(B) which is titled "Securing" it does not say that. Perhaps the inspector just needs reminded of what 330.30(C) says. :happyyes:The reference I gave says that the holes in the studs count as securing and supporting.

Here are the pertinent subsections...The securing part comes into play when we get to the box so I see Dave's point as important.
(B) Securing. Unless otherwise provided, cables shall be secured
at intervals not exceeding 1.8 m (6 ft). Cables containing
four or fewer conductors sized no larger than 10 AWG
shall be secured within 300 mm (12 in.) of every box, cabinet,
fitting, or other cable termination. In vertical installations,
listed cables with ungrounded conductors 250 kcmil and
larger shall be permitted to be secured at intervals not exceeding
3 m (10 ft).
(C) Supporting.Unless otherwise provided, cables shall
be supported at intervals not exceeding 1.8 m (6 ft).
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.
Here are the pertinent subsections...
So how do you see the statement in (C) as affecting the requirement in (B) to secure within 12 in.? Must we secure within 12 in. always, even when the run is horizontal through a stud within 6 ft. Can we forego any other type securing?
Why is there no statement in (B)?
I would say that if it goes horizontally through a stud within 12" of the box you are OK.

Makes sense to me... but it is up to the inspector to make the same call.I agree, I always think of the hole in the stud as the equivalent to something like a staple.
Always!Makes sense to me... but it is up to the inspector to make the same call.
Does he want you to use re-bar/bailing wire to tie it down? Then you have to show him the UL listing on that.:happysad:
The horizontal support and secure clause was introduced in the 1999 NEC as 334-10(A)(1). I recall wiring a WalMart store prior to that cycle and having to secure the MC every fourth stud in all the walls.Thanks everyone for the help. I found out that's just his preference and my foreman didn't want to argue with him. Lol
