By Dave Rongey Electrical Question - Summary: How many romex 12-2 and how many 14-3 wires am I able to run through an interior wall separating two rooms?
Great Question!
There is no limit as to how many Romex wires you can run between two rooms, the method would be the factor.
The path for the Romex wiring must be installed using methods which will protect the wiring from nails and screws used to install sheet rock and other wall coverings.
Drill the holes for the Romex in the center of the wall studs or framing material. If the holes get too close the outside of the studs, then be sure to protect the Romex by using Safety Plates, also know as Nail Plates.
Below you will see some photos of recent projects that I have selected to help you with your project. [Click on the images to Enlarge]
In areas where the wiring may be vulnerable to harm of sheet rock screws or nails, always install Safety Nail Plates to protect the wiring!
Routing wiring through corners is a special area of concern because the sheet rock will be anchored securely in this area.
The wiring should be back 1-1/2' away from both nailing surfaces - Interior and Exterior.
