Installing Electric Wiring into a container

How to install electric wiring into the walls of a shipping container. The CX 44 Panel has built in horizontal and vertical raceways, meeting the national electrical code for Romex® wires without the use of protection plates.
In the video we will show you how to wire a shipping container with Romex® type wire. Wiring is really pretty simple to install. Individual runs can be pushed or slid through the horizontal or vertical chase ways up to 20′ from box to box.

Specialty Tools to make the job easier

Hot knifes are not essential for installation. For more information about specialty tools

The stick was used to help set a consistent height for the electrical boxes.
The orange tape was used to illustrate the electrical wiring runs and their location in our panels. Preplan all of your electrical cuts. Keep the hot knife...HOT!

The hot knife is a plunge cutting tool. Save the cutout pieces of foam for use later to replace the electrical box cuts.

Keep the Wire Flat and Kink Free

Keep the Wire Flat and Kink Free;

To keep the wire flat and kink free. We used a turnstile to unreel the 12 gauge Romex wire.

Bend the Romex over to reduce snags when thearding the wire throught the wall.

We ran the 12-gauge Romex wire behind the PVC water pipe. Keep the glue away from the electrical raceways.

Wiring Transitions to Frame Walls

Wiring Transitions to Frame Walls

To transition from an InSoFast wall to a frame wall locate the horizontal or vertical raceways in the InSoFast panel.  Locate the stud punch out over the open raceway in the InSoFast panel pull wire through. Follow standard code approved installation procedures. Fill any gap around all the electrical cuts or openings with the expanding foam.

Running Wire Around Corners

When Changing direction, you will have to cut a hole to access the raceways. Save this piece to glue back in after your electrical inspection.

When routing wires up the wall into the ceiling, cut access holes at the top of the wall on the ceiling at the raceway locations. The raceways will not match up. Run the wire along the top of the CX44 panel, making sure to push the wire all the way back to the beam. Code requires thatthe wire be 1-1/4" back from the face otherwise a metal protection plate is required.

The electrical boxes can be adhered or mechanically attached. Verify with electrical inspector for local code requirements

InSoFast panels are designed for use with standard Romex® (NM sheathed wire), MC Flex, AC Flex, or rigid metal conduit.

E3802.1 Installation and support requirements

Wiring methods shall be installed and supported in accordance with Table E3802.1.

Where run parallel with the framing member or furring strip, the wiring shall be not less than 11/4 inches from the edge of a furring strip or a framing member such as a joist, rafter or stud or shall be physically protected. (InSoFast panels raceways satisfy the required protection of 1¼”)
Bored holes in framing members for wiring shall be located not less than 11/4 inches from the edge of the framing member or shall be protected with a minimum 0.0625-inch steel plate or sleeve, a listed steel plate or other physical protection.( Raceways that are running through InSoFast studs do not require steel plates because they meet the 1 ¼” depth requirement)
Where installed in grooves, to be covered by wallboard, siding, paneling, carpeting, or similar finish, wiring methods shall be protected by 0.0625-inch-thick steel plate, sleeve, or equivalent, a listed steel plate or by not less than 11/4-inch free space for the full length of the groove in which the cable or raceway is installed.(InSoFast panels are engineered with a groove that forms a raceway with the required protection or “free space” of 1 ¼” along the full length of the groove)
Securely fastened bushings or grommets shall be provided to protect wiring run through openings in metal framing members. (InSoFast panels have no metal or sharp edges)
The maximum number of 90-degree bends shall not exceed four between junction boxes.(This does not apply to NM or Romex® wiring)
Bushings shall be provided where entering a box, fitting or enclosure unless the box or fitting is designed to afford equivalent protection. (does not apply to NM or Romex® wiring)
Ends of raceways shall be reamed to remove rough edges. (Raceways of InSoFast panels have no metal or sharp edges )
Maximum allowable on center support spacing for the wiring method in feet. (The raceways of InSoFast panels provide continuous confinement and support for wiring)
Maximum support distance in inches from box or other terminations. (NM or Romex® wiring must be secured in place within 8” of boxes without cable clamps. Securing wiring with expanding foam adhesive (Great Stuff®) satisfies this requirement)
