If you are going to continue to run the cable behind the studs then you must fasten it every 4 feet. I would say the guy that ran those cable was no electrician. __________________ Do not PM with questions that can be asked in a forum. I will not respond.

It is a metal pole barn that doesn't come with traditional stud walls. I'm trying to separate some of the space into a different room so am putting up the walls myself. Does that explain it? I can post more pics if you need them.

It doesn't have stud walls as built, but I have been adding them so I can add insulation and drywall. The electrician wired it and attached the boxes to the horizontal 2x6s in the pics. I have been moving the boxes to the vertical studs as I build them. Attached Thumbnails

One wire in bottom and one in top is fine. The outside of the building is metal. The inside is wrapped by double bubble insulation. Is that considered a vapor barrier?

Single gang boxes do not have clamps, just knockouts. The KO's can accept two cables. __________________ Answers based on the National Electrical Code. Local amendments may apply.
