Summary: Here is a Great Electrical Wiring Question - Frank from Illinois asks: How many romex 12-2 and how many 14-3 wires am I able to run through an interior wall separating two rooms?In this article on Home Wiring Remodel Tips we will take a look at how to safely install romex house wire and methods to protect the wire from damage.
The Protection of Electrical Wiring is Extremely Important
Safe Wiring Practices
Always use the correct size wire for your circuit. If adding onto an existing circuit make sure to match the existing wire size and type.
Install wiring so that it is protected and will not be damaged by dry wall or wall covering fasteners such as screws or nails.
Drill holes in the center of the framing stud. Before drilling holes look on the opposite side of the framing stud to be sure it is clear of other wiring, pipes or any other existing such system device components.
Always use Metal Safety Plates to protect the electrical wiring where it could be damaged from wall covering nails or screws.
Great Electrical Wiring Question - Here is the Answer!
There is no limit as to how many Romex wires you can run between two rooms, the home wiring method would be the factor when wiring remodel construction projects.
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 used for your remodel construction. If the holes get too close the outside of the studs, then be sure to protect the home wiring or Romex by using Safety Plates, also know as Nail Plates.

In areas where the home wiring may be vulnerable to harm of sheet rock screws or nails, always install Safety Nail Plates to protect the wiring!
When remodeling, routing wiring through corners is a special area of concern because the sheet rock will be anchored securely in this area.
The electrical wiring should be back 1-1/2' away from both nailing surfaces - Interior and Exterior.
