Cable run problem

Hi all, I'm in the process of remodeling my 2nd floor of my home. No doubt many of you veteran electricians must have come across the building techniques used when a home was built in the 1800's. My plan is to install a 3 way switch at the bottom and top of the stair way. The problem I have is the 2x4's they used were never installed the way they are today; Today you have a 4 inch deep wall (okay closer to 3 and 1/2 inch deep). Back when this house was built, the 2x4's were installed in such a way that the wall is only 2 inches thick. Can I use MC 12-2/G cable or is there a better/cheaper way to do this? Thanks, Roger

You just need to keep the cable at least 1 1/4 inch from the side of the studs. Something like a Colorado Jim would work to secure the cable. You will need to use metal boxes with plaster rings since the wall is so shallow.

As PC said, you just need to keep the cable 1 1/4" away from the nailing face of the stud. You can use NM-b cable instead of more expensive MC cable (If allowed in your area).

pcboss, Tolyn Ironhand; Thank you for your help. I have never heard of a Colorado Jim. I'll have to google it and see what I come up with. Roger

Another question regarding the Colorado Jim (I Googled it and I can see how it would work my situation). Can NM-b, coax and Cat6 EtherNet cable be in the same bracket? Or do they need to be in separate brackets? Roger

Normally it is recommended to keep line voltage cables, and communication cables, separated by 12" or more when run parallel to each other.
