Hide Frame TV Power Cord (One Connect In-Wall Boxes)
To hide a Frame TV’s cables safely, keep its ordinary power cord out of the wall. Use a listed power-relocation kit or a properly installed receptacle, and route the One Connect cable inside the wall only when its exact rating and Samsung’s instructions allow it. Keep required boxes accessible, preserve airflow, and follow local code.
A clean wall can make a mounted Frame TV feel like part of the room, not a display surrounded by wires. It can also reduce loose cords that collect dust or get caught during cleaning. The key is not to conceal every cable by any means available. Power and signal cables have different rules, and the One Connect cable is not automatically safe for in-wall use just because it carries a signal.
I start by identifying the exact TV, box, and cable, then choose a power method that matches the equipment instructions and locally adopted electrical code. That small planning step helps prevent damage, failed inspections, and costly wall repairs.
Plan around the exact TV and One Connect cable
Planning means confirming which Frame TV and One Connect system you have before choosing a box or cable route. Samsung’s cable types and placement instructions can differ by model. Read the TV and One Connect manuals, and use the cable’s own markings to confirm whether it is approved for the planned concealed route.
Record model and cable details
The TV model is the starting point, but it is not enough by itself. Record the One Connect box model, cable part number, cable-jacket markings, and the revision or date of the installation manual. Compare those details with Samsung’s instructions for cable routing, minimum bends, placement, and ventilation.
Do not infer an in-wall rating from a cable’s thin shape, fiber-optic design, or low-voltage use. If the cable has no clear marking, or the manual does not approve concealed installation, contact Samsung or use an approved alternative pathway. A conduit does not make an unrated cable suitable for a wall.
Choose a compliant power method
A listed power-relocation kit moves a receptacle connection to the TV location using the kit’s specified parts and installation method. Another option is a code-compliant receptacle installed behind the TV by a qualified electrician. In either case, keep the TV’s ordinary detachable power cord outside the wall.
| Option | What it does | Best fit | Key check |
|---|---|---|---|
| Listed power-relocation kit | Provides a specified in-wall power path and outlet location | The kit’s instructions match the wall and installation | Use the complete listed assembly as instructed |
| New receptacle at TV | Places a standard outlet behind the screen | A permanent installation or a simpler cable layout | Have it installed to local code |
| Surface raceway | Covers cords on the wall without concealing them in the cavity | Renters or walls where cutting is unsuitable | Use a product rated for the intended cords and location |
Before buying a kit, confirm its listing, installation instructions, box locations, and compatibility with the wall type. A generic product description is not a substitute for its actual instructions. Ask your local building department whether a permit or inspection is required.
Know the code limits before opening the wall
Electrical code requirements depend on the edition adopted in your area and on the specific installation. The key principles are clear: do not conceal an ordinary flexible power cord in a wall, follow listed equipment instructions, and keep required boxes accessible. Confirm local requirements before cutting or wiring.
Keep ordinary power cords outside the wall
NEC 400.12(2) prohibits flexible cords from being run through holes in walls, structural ceilings, suspended ceilings, or floors. That includes the TV’s ordinary detachable mains cord. Do not route it through drywall, inside a wall cavity, or through conduit to make it appear concealed.
NEC 110.3(B) requires listed or labeled equipment to be installed and used according to its instructions. For a power-relocation kit, that means using its specified components, connections, and placement. Do not substitute an extension cord, splice, or different outlet part unless the kit instructions permit it.
Keep boxes reachable and the One Connect box ventilated
NEC 314.29 requires outlet and junction boxes to remain accessible without removing building finish. Do not bury a splice, kit connection, or required box behind drywall. The One Connect box also needs service access; do not permanently close it inside the wall.
There is no universal NEC airflow number or TV-to-wall clearance for every One Connect box. Follow the instructions for your exact model, keep vents unobstructed, and leave room for service. Article 725 rules can also affect separation between power conductors and Class 2 or communications wiring. The permitted method depends on the adopted code and equipment; use an approved barrier, separate compartments or raceways, or another method specifically allowed. Do not assume one spacing rule applies to every job.
Route approved parts and finish the wall
Installation starts with a careful wall survey, not a saw. Find framing, fire blocking, insulation, and existing wiring or plumbing, then confirm that the planned route will not damage a rated wall assembly. If the path is unclear, pause and get qualified help rather than guessing.
Survey the route and place the boxes
- Mark the TV, power-kit, and One Connect box positions. Check the mount’s range of movement and the cable’s path before cutting.
- Use suitable tools to locate studs and check for hidden services. A basic stud finder may not detect every pipe or wire, so treat uncertain areas with care.
- Check for fire blocking and any fire-rated construction. Do not leave an opening or route that defeats a required firestop; restore the assembly using a suitable method.
- Place the kit’s boxes where its instructions allow and where connections remain accessible. Make sure the One Connect box can be reached and ventilated as Samsung directs.
If the wall has insulation, masonry, unusual framing, or an unknown fire rating, the route may need a different method. A surface raceway or professional installation can be safer than forcing a concealed route.
Install the power path and route signal cable separately
Follow the kit instructions exactly, including box orientation and the designated supply and outlet components. If you choose a new receptacle instead, have it installed in a manner that complies with the locally adopted code. Do not join the TV’s factory power cord to an in-wall wiring run.
Pass the One Connect cable through the wall only if the exact cable is marked or otherwise documented as suitable for that concealed use and Samsung permits it for your model. If not, use a manufacturer-approved in-wall cable or an approved accessible pathway. Do not pinch, sharply bend, pull tight, or trap it behind the TV mount.
After the work, secure the boxes and cables as instructed, preserve access to connections, and restore fireblocking where required. Mount the TV, place the One Connect box in its approved location, and check that its vents are clear.
Compare common installation situations
A useful installation plan matches the cable and wall conditions, not just the desired look. These examples show how the same Frame TV goal can call for different solutions. They are practical scenarios, not a claim that every home has the same framing, cable, or code requirements.
Scenario: cable rating is unclear
If a cable has no legible rating and the manual does not clearly approve in-wall use, do not conceal it. In a typical planning visit, I treat that as a stop point: confirm the cable specification with the manufacturer, or choose an approved cable or accessible route. The safe answer is based on the exact part, not its appearance.
Scenario: rental or finished wall
A renter, or a homeowner who does not want to open a finished wall, can use a surface raceway suited to the cable and location. It will not make the cord disappear inside the wall, but it can create a neat, removable route. Check lease terms before attaching or cutting anything.
Scenario: no safe path behind the TV
A stud, fire block, pipe, or wiring may block the planned route. Do not drill through framing or move a box without checking what is behind it and whether the change is allowed. An electrician or qualified installer can assess another route, a new receptacle location, or a surface solution.
Verify the installation before using the TV
Verification means checking the equipment, access, routing, and operation after installation. It is the final chance to catch a pinched cable, blocked vent, hidden connection, or incorrect kit part before the TV is in regular use. Keep the documents so later service does not depend on guesswork.
Run this final check
- Confirm the power kit’s listing and that its exact components were installed as directed.
- Confirm the One Connect cable’s markings and approved use for the concealed route.
- Check that required outlet, junction, and kit connection points remain accessible.
- Check the One Connect box’s vents and service access against the model instructions.
- Ensure the cable is not pinched, sharply bent, tensioned, or trapped by the mount.
- Test the TV and connected devices. Where required, arrange inspection by the local authority.
- Keep model numbers, cable and kit documentation, and permit or inspection records.
If the TV loses signal or the box becomes unusually warm, turn it off and check the cable path and ventilation against the manufacturer’s instructions. Do not solve the problem by sealing the box into a tighter space.
Frequently asked questions
These answers address the main decisions behind a clean Frame TV installation: which cords can enter a wall, what to do with the One Connect cable, and how to keep boxes compliant and serviceable. Always check your exact model instructions and the electrical rules adopted where you live.
Can I put the Frame TV’s power cord inside the wall?
No. NEC 400.12(2) does not permit an ordinary flexible power cord to run through a wall. Use a listed power-relocation kit as instructed or have a compliant receptacle installed at the TV.
Can the One Connect cable go inside the wall?
Only if the exact cable is suitable for that concealed use and Samsung’s instructions permit it for your model. Verify its markings and documentation before routing it.
Does a conduit make any cable safe for in-wall use?
No. Conduit does not change a cable’s rating. Use only a cable approved for the route and installation conditions.
Can I hide the One Connect box inside the wall?
Do not bury it or block its vents. Keep it accessible and follow the ventilation and placement instructions for the exact box model.
Can I cover a junction or kit connection with drywall?
No. NEC 314.29 requires covered outlet and junction boxes to remain accessible without removing building finish.
How much space does the One Connect box need?
There is no single clearance that applies to every model. Follow Samsung’s instructions and keep all vents unobstructed.
Do power and One Connect cables need a set spacing?
The applicable separation rules depend on the adopted NEC edition, wiring method, and equipment. Use a method specifically permitted by code and the kit instructions rather than assuming a universal gap.
Can I install an in-wall kit myself?
It depends on the kit instructions, local rules, and your skill. Check permit and inspection requirements. Hire an electrician if the work involves unfamiliar wiring, an uncertain wall, or a new receptacle.
What if I cannot confirm the One Connect cable’s rating?
Do not conceal it until you confirm its suitability. Ask Samsung about the exact part number or use an approved accessible route.
A seamless result depends on keeping the right parts in the wall and the right parts accessible. Confirm the TV and cable details, use an approved power method, preserve ventilation and access, and document what you install. If any rating or route is uncertain, stop and verify it before closing the wall.
