If permitted, new electrical wiring may be run behind baseboards to serve a new wall receptacle, or to a switch and new ceiling light fixture. To pass the cable through the wall studs a notch is cut in the wood and a metal shield, sometimes called a nail guard, is fastened over the notch to protect the new wires from nail and screw punctures.
This method will not work with thinner wall material such as ½inch drywall, at least ¾inch of wall material is needed to bury the metal sheath. For walls less than ¾inch, the studs behind the baseboard can be notched to run a new NM cable and a metal plate used at each stud to protect the wires from punctures.
