Hide Samsung Frame Cable in Wall (Conduit Box)
To conceal a Samsung Frame’s One Connect cable, first verify that the exact cable is approved for in-wall use. A conduit or brush plate does not change its rating. Keep the TV’s flexible AC cord out of the wall; provide power through a properly installed receptacle or listed in-wall power kit. Check the TV instructions and local code before cutting.
Plan the route and identify the cable
Start by identifying the parts, wall conditions, and local rules before making an opening. The One Connect cable carries the TV’s connection to its One Connect box, but its appearance or product name does not prove it can go inside a wall. Confirm the cable’s approval and plan a separate, compliant way to power the TV.
I start by recording the TV model, One Connect box model, cable part number, and any markings on the cable jacket. Then I check the model-specific Samsung instructions and documentation for that exact cable. Samsung products and cable versions can differ, so an approval for one cable should not be assumed to apply to another.
A cable listing is evidence that a cable has been tested and approved for a stated use. For concealed low-voltage wiring, look for the marking and documentation required for the intended installation, such as a suitable CL2 or CL3 rating where applicable. Do not treat “One Connect,” “Invisible,” or “Slim” as proof of an in-wall rating.
If the cable’s rating or Samsung’s approval cannot be verified, do not conceal it. Ask Samsung or the cable manufacturer for guidance, or obtain the specified in-wall cable. Keep an unverified cable visible until you have a confirmed option.
Before planning the route, note the wall type, stud locations, nearby receptacles, and the location of the One Connect box. Look for possible plumbing, wiring, insulation, and fire blocking. A wall with a fire-rated assembly may have extra limits on openings and repairs; check local requirements before changing it.
Next step: Write down the model and cable details, then confirm the exact cable’s in-wall use before choosing a pathway.
Keep TV power separate from the One Connect cable
The One Connect link and the TV’s AC power cord serve different purposes and must be treated differently. A low-voltage cable may be concealed only when its rating and instructions allow it. A TV’s flexible power cord must not be hidden in a wall, even when it passes through conduit or a brush plate.
The supplied AC cord is a flexible cord. NEC 400.12 generally prohibits concealing flexible cords in walls. Putting the cord inside a conduit does not make that concealed route acceptable. Do not use an extension cord in the wall either.
Instead, use one of these approaches:
- Have a suitable receptacle installed behind the TV by a qualified person where required.
- Use a listed in-wall power-relocation kit, installed exactly as its instructions require.
- Keep the TV’s power cord outside the wall if neither in-wall option is suitable.
A power-relocation kit is a listed assembly that provides a compliant way to move power to the TV area. Follow its instructions for the source connection, destination module, wiring method, and installation. Do not substitute loose parts or assume that a low-voltage pass-through kit can carry AC power.
Keep line-voltage wiring and low-voltage cable separated as required by the applicable wiring rules. NEC 725.136 and other relevant rules address separation. Do not place them together in one unpartitioned opening unless the specific code conditions permit it. A low-voltage brush plate is not a power outlet.
Electrical boxes also need to remain accessible. Under NEC 314.29, covered boxes must be accessible without removing building finish. Do not bury a receptacle, junction box, or splice behind drywall, a panel, or fixed trim.
Next step: Decide on the TV power method before opening the wall, and check that it meets the kit instructions and locally adopted code.
Choose and install a suitable pathway
A conduit or pass-through gives an approved cable a protected route; it does not make an unapproved cable safe to conceal. Size the pathway for the cable and its connectors, and follow the cable maker’s handling instructions. There is no universal conduit diameter or bend radius for every Samsung setup.
A pathway is the route and hardware used to guide a cable through or behind a wall. Depending on the product and wall, that may be a listed low-voltage pass-through system or conduit. Check the pathway’s listing and instructions, including allowed cable types, opening size, and bend limits.
Step-by-step installation
Use this sequence to reduce avoidable wall damage and keep the installation serviceable. If the work involves branch-circuit wiring, a fire-rated wall, or a code question you cannot resolve, pause and get qualified help before cutting or closing the wall.
Survey the wall. Locate studs and check for electrical wiring, plumbing, insulation, and fire blocking. Confirm that the planned openings will not damage a rated wall assembly or create a penetration that needs a specific firestop detail.
Mark the endpoints. Plan one opening near the TV and another where the One Connect box will sit. Leave the box and connectors reachable for service. Check the cable’s route length before cutting; it should reach without tension.
Confirm components. Use a listed low-voltage pathway for the verified One Connect cable. Separately, select a suitable receptacle or listed in-wall power kit for TV power. Follow each product’s instructions; do not combine power and low-voltage conductors in a shared, unpartitioned space unless the code allows that specific arrangement.
Protect framing. Under NEC 300.4(A)(1), when a bored hole is less than 1¼ inches (32 mm) from the edge of a framing member, protect the cable with a steel plate at least 1⁄16 inch (1.6 mm) thick, or an equivalent permitted by code. Check the locally adopted code and the installation conditions.
Install and pull carefully. Fit boxes and pathway parts as instructed. Do not force a connector through a conduit, crush the cable, stretch it, or make a sharp bend. Follow Samsung’s handling guidance for the exact cable.
Check before finishing. Confirm that the cable reaches both devices with no pull or kink, and that its connectors can be accessed. Keep electrical boxes accessible. Complete any required inspection and restore firestop materials where the wall assembly requires them before patching and painting.
Next step: Keep the pathway within the cable and component instructions, and leave access for future service.
Compare concealment options and verify the result
The right option depends on the cable’s verified rating, the wall, and how power will reach the TV. Comparing those details before work begins can prevent an unsafe shortcut and reduce the need to reopen a finished wall. Use the table as a planning aid, not a substitute for product instructions or local code.
| Option | One Connect cable | TV power | Best fit | Main check |
|---|---|---|---|---|
| In-wall low-voltage pathway | Only if the exact cable is approved for concealed use | Separate compliant receptacle or power kit | A verified in-wall-rated cable and a suitable wall route | Cable listing, pathway instructions, and separation |
| Listed in-wall power-relocation kit plus low-voltage pathway | Only if approved for in-wall use | Through the kit, installed as listed | When a compliant power location is needed behind the TV | Kit instructions and electrical requirements |
| Surface raceway | Routed on the wall, not inside it | Use a suitable surface power method; do not hide a flexible cord in the wall | When the cable cannot be verified or wall access is limited | Raceway compatibility and power method |
| Visible cable, neatly managed | Remains outside the wall | Use the supplied cord as instructed | When approval or wall conditions are unclear | Secure routing without pinching or damaging the cable |
Before concealing anything, I verify four things: the cable identification and approval; the power installation; the cable’s function and connector seating; and access to boxes and the One Connect box. Check the One Connect box manual for ventilation clearance rather than placing it in a sealed cavity.
Take photos of the open-wall route and note where the boxes and pathway sit. These records can help with future repairs or changes. If an inspection is required, arrange it before closing the wall.
Common installation scenarios
These examples describe planning patterns, not a substitute for checking a particular home or Samsung model. The same-looking TV setup can need a different solution if its cable, wall construction, or local rules differ.
- Cable approval is unclear: Keep the cable outside the wall while you confirm the part number and documentation. A conduit does not resolve the uncertainty.
- The cable is verified, but power is not planned: Stop before cutting. Choose a compliant receptacle or listed power-relocation kit first.
- The framing route puts a hole close to an edge: Apply the required framing protection, including the NEC 300.4(A)(1) threshold where applicable.
- The wall contains a junction or receptacle in the proposed path: Do not cover it. Keep the box accessible and revise the route if needed.
Next step: Test and document the installation before patching the wall.
Frequently asked questions
These answers focus on the two checks that matter most: whether the exact One Connect cable can be concealed and how the TV receives power. When instructions or code rules differ, use the model-specific Samsung guidance and the locally adopted electrical code.
Can I put the Samsung One Connect cable inside a wall?
Only if the exact cable is approved for the intended in-wall use. Check its markings and Samsung documentation for your models. If you cannot verify approval, keep it outside the wall.
Does conduit make an unapproved One Connect cable safe to conceal?
No. Conduit provides a pathway, but it does not change a cable’s rating or approval. Use only a cable approved for the installation.
Can I run the TV’s supplied power cord through the wall?
No. NEC 400.12 generally prohibits concealing flexible cords in walls. Use a properly installed receptacle or a listed in-wall power-relocation assembly instead.
Can I run the power cord through conduit inside the wall?
No. Concealing the flexible cord in conduit does not make the installation acceptable. Choose a compliant in-wall power solution.
Can the One Connect cable and TV power wiring share one opening?
Do not put them together in an unpartitioned space unless the specific code conditions allow it. Follow NEC 725.136, applicable wiring rules, and the product instructions.
How large should the conduit be?
There is no single size for every cable and connector. Size the pathway for the exact cable and connectors, and follow the pathway maker’s instructions. Do not force a connector through it.
What does the 1¼-inch framing clearance rule mean?
Under NEC 300.4(A)(1), a bored hole less than 1¼ inches (32 mm) from a framing-member edge needs a steel plate at least 1⁄16 inch (1.6 mm) thick, or a code-permitted equivalent.
Can I cover a junction box after the TV is mounted?
No. NEC 314.29 requires covered electrical boxes to remain accessible without removing building finish. Do not bury a box, receptacle, or splice.
Should I test the system before patching the wall?
Yes. Confirm cable function, connector seating, power operation, box access, and the One Connect box’s manual-specified ventilation clearance before finishing the wall.
