Re: Article 314.17
Actually them spots are intended to hold the wire.So his point is somwhat valid.However if you have a stable holding the wire i see no problem.It comes down to the listing of the box and what it was aproved for.

Re: Article 314.17
I fail to see the relevance 314.17 has on the installation, unless he's misreading it, or you're missing his point.
So if 314.17 was cited, perhaps one (or all) of the cable clamps fell out of the box?
The NM is to be stapled within 12" of the box. (334.30)
If it were a single-gang box, you can omit the cable clamp if you staple within 8" of the box (314.17(C), exception).
I agree with Jim. If he's got a beef with a 14-2 and a 14-3 in the same KO, he should be citing 110.3(B). Chances are your box and clamp aren't listed for both at the same time.

You're working with NM, not knob & tube.

Re: Article 314.17
The exception to 314.17(C) states that "multiple cable entries shall be permitted in a single cable knockout opening." I take that to be in reference to the prior sentence referring to single gang boxes. I don't believe you are permitted to have multiple cables enetering a single knockout opening in a multi gang box, unless specifically stated in manufacturer's instructions.
There may be others on the site who take the last sentence of the exception as a stand alone sentence, thereby allowing that practice.

Re: Article 314.17
"this ia muli- box 4 gang with 4 3 ways."
The exception to 314.17(C) is for single gang plastic boxes.
since you are using a multigang box, the exception is not applicable. If the listing of the box permits more than one cable per clamp, it would be acceptable. I doubt whether the manufacturer would permit more than one cable per clamp. If you tell us the manufacturer of the box installed, we can look it up and tell you if you are permitted to do so.
Stapling the cable to the framing is not the same as securing it to the box. Multigang type boxes are required to have the cable secured to the box.

In my area we are required to install one wire per hole in any nonmetallic multi-gang box.
