How to Route Cable Through Steel Studs

Steel studs and wooden studs have different code requirements for proper cable penetration and routing. Metal studs present sharp edges and the potential ability for a short circuit, should the cable's outer jacket become compromised. Passing cables properly through metal studs allows peace of mind that the wires are correctly routed, while meeting the approval of your local electrical inspector.

Instructions

- 1
  Locate the knockouts on the sides of each metal stud. Snap a plastic grommet into each knockout, protecting the jacket of the wire as it passes through.
- 2
  Slide the wire from the beginning point through the studs and grommets. Define the location(s) where the wire will terminate.
- 3
  Knock out the perforated panel on the junction box, using the screwdriver and hammer. Discard the perforated piece you punched out.
- 4
  Screw the junction box to the desired outlet or access plate location, using two sheet metal screws. There are two holes on the side of the box for the screws.
- 5
  Slide the wire into the junction box, leaving sufficient quantity inside the box to easily work with after construction is finished. Typically, six to eight inches is enough.
- 6
  Coil the wires inside the junction box. Secure the bundle with a plastic zip tie or a length of electrical tape.
