question about flex armoured cable runs

had an electrical run made on an exterior wall in the attic. This nm 14-2 cable i feel like should of been installed into an armored cable at least.

The attic space is being converted into a bedroom. i know code wouldnt' allow this but if you were running a 14-2 cable along an exterior non framed wall. cable sitting along plywood behind 2x4 studs. Im thinking the siding guy down the road is going to hit this cable.

wouldnt it of been common practice to at least protect this cable.

NM cable can be installed in open stud walls, but it must be run through holes or stapled at least 1-1/4" from the face of the framing. Armored cable is not required in an attic space, and doesn't really make much difference in terms of protection required for the cable.

That framing looks way off to me.
Bottom of the wall is framed like balloon wall construction which is not allowed.
By having the 2 X 4's laying flat against the wall leaves no room for insulation.
When adding a bedroom most areas require permits, and need to go through zoning and the heath dept.

Armored cable (MC/AC) provides no protection from nails of screws and have the same requirements and NM cable when run through framing members. The outside jacket is only aluminum. The cables need to be kept 1 1/4" away from any nailing face inside or out, or have protective nail plates installed. I suggest adding some 1 1/2" strapping to your framing.

I suggest straightening up that mess like has already been mentioned.

it must be run through holes or stapled at least 1-1/4" from the face of the framing.
OR.....hire an electrical contractor who will do it right.
