Hide Power Strips and Plugs (Cable Hider Boxes)
A cable-management box can hide a power strip and plugs while keeping them accessible, but the enclosure must suit the strip and allow heat to escape as its manufacturer directs. Keep the strip’s flexible cord outside walls, floors, and ceilings. Check product listings, ratings, fit, and ventilation before use; if the instructions do not allow enclosure, leave the strip uncovered.
A tidy room should not come at the cost of a hidden heat problem or a damaged cord. A purpose-made cable box can keep a power strip and its plugs out of sight, reduce casual contact, and make dusting easier. Choosing the right box can also save money over time: a good fit may protect cords from everyday snags, while avoiding an unsuitable enclosure can prevent damage and early replacement.
I often see the same challenge after a TV or desk setup is complete: the devices work, but the plugs and power strip remain in plain view. The safe answer is usually not to put them behind drywall or inside a decorative container. It is to use an enclosure intended for this purpose, follow both products’ instructions, and keep the setup open to inspection.
Planning: Identify the Strip, Box, and Applicable Instructions
Start by identifying the exact power strip and cable box, then read the labels and instructions for both. Those details decide whether the products can be used together. There is no universal box size or airflow number that makes every power strip safe to enclose, so do not judge by appearance alone.
A relocatable power tap is a portable power strip with multiple outlets. UL 1363 is a standard for these devices; check the strip’s markings for its applicable listing and electrical ratings. A listing does not mean the strip can be used in any enclosure. Its own instructions still matter.
The NEC also provides two important guardrails. Section 110.3(B) says listed or labeled equipment must be installed and used according to the instructions included with its listing or labeling. Section 400.12 restricts how flexible cords may be used, including prohibiting them from being concealed by walls, floors, or ceilings or run through building openings.
Before shopping or setup, record:
- The strip’s model, listing marks, and marked voltage, current, and wattage limits.
- The box model and whether its maker specifically allows use with a power strip.
- Any stated spacing, ventilation, mounting, and access requirements.
- The location of the receptacle and the path the strip’s cord must take.
If the box maker gives no suitable instructions for enclosing a power strip, do not assume a lid or vent slots make it safe. Choose a different enclosure or leave the strip unenclosed. Local code adoption and amendments can vary; the local authority having jurisdiction governs.
Access and Clearances: Keep Plugs Reachable and Cords Unstrained
A box should conceal the clutter, not make the strip hard to inspect or create pressure on plugs and cords. The interior needs room for the strip, inserted plugs, cord bends, and all clearances required by the product instructions. There is no code-wide minimum dimension for this use.
Measure the actual setup rather than relying on the strip’s body length alone. Right-angle plugs, bulky adapters, and cords that exit from the sides can take more room than expected. Do not force the lid closed, coil cords tightly to make them fit, or press cables against vents.
Keep the strip and its controls reachable enough to check or disconnect them. The wall receptacle should also remain accessible for normal use and inspection. A box that must be moved, emptied, or dismantled just to reach a plug may not be a practical choice.
| Setup detail | What to check | Better choice when it does not fit |
|---|---|---|
| Strip and plug dimensions | All parts fit without pressure | A larger enclosure approved for the use |
| Cord bends | Cords curve naturally and are not pinched | Reposition the strip or choose another box |
| Vent openings | The strip’s vents remain clear | A model with suitable ventilation, if allowed by both makers |
| Lid and access | The lid closes as instructed; plugs remain reachable | Leave the lid open only if instructions allow, or do not enclose |
| Mounting | The maker permits the chosen surface or mount | Place on a stable surface as directed |
Do not treat a generic storage bin, basket, or closed decorative box as a cable enclosure. Its fit and ventilation may be unsuitable, even if the strip physically fits inside. The key test is not “Can I close it?” but “Do both manufacturers permit this use?”
Execution: Position and Route Without Concealing Flexible Cord
Set the box on a stable surface or mount it only in the way its manufacturer allows. Place the strip so its vents and controls are unobstructed, then connect devices without stretching or crushing the plugs. The flexible cord must remain outside building cavities and finishes.
A simple setup sequence helps catch problems early:
- Confirm the receptacle, strip, and enclosure match the instructions you reviewed.
- Place the enclosure near the receptacle so the strip cord reaches without tension.
- Arrange plugs and cords loosely inside the box, leaving required clearances.
- Route the strip’s cord along an exposed, safe path to the receptacle.
- Close or secure the enclosure only as its maker directs.
Do not run the strip’s cord through a wall, floor, ceiling, door, or window. Do not staple it, pinch it behind furniture, or extend it through a building opening to hide the route. A power-strip cord is flexible cord, not a replacement for fixed building wiring.
For a cleaner look, position the enclosure behind furniture only if it remains accessible and the furniture does not press on it or block its vents. A cable box can hide the strip and plugs, but it does not make an unsafe cord route acceptable.
Verification: Check Ratings, Ventilation, Access, and Heat
Before relying on the setup, verify that the strip’s marked limits are not exceeded and that the enclosure is used as instructed. Check for damaged cords, blocked vents, tight bends, and difficult access. During initial use, watch for abnormal warmth; stop using the setup if overheating occurs.
Compare the combined load of connected equipment with the strip’s marked voltage, current, and wattage limits. Do not guess from the number of outlets. If a device’s demand or the strip’s rating is unclear, consult its label or manufacturer rather than assuming the load is acceptable.
A closed box can trap heat, even when the strip fits. No general NEC clearance or airflow figure makes an arbitrary lidded container safe. Use an enclosure expressly suitable for the strip and follow its stated ventilation requirements. If neither manufacturer provides instructions that support enclosed use, leave the strip uncovered.
Check the setup again after moving furniture or adding a device. Make sure:
- No cord is damaged, strained, pinched, or hidden in building construction.
- The strip’s vents and the enclosure’s required openings remain clear.
- Plugs are seated without pressure and the lid is used as directed.
- The strip and receptacle remain accessible.
- The marked electrical limits are respected.
If you notice unusual heat, odor, discoloration, or other signs of a problem, disconnect the equipment if it is safe to do so and stop using the setup until you can identify and correct the cause.
Real-World Setups: Choose a Box for the Actual Layout
The right enclosure depends on where the strip sits, how many plugs it serves, and what the instructions allow. These common layouts show how to apply the checks without assuming that one box works for every room.
In a TV area, I commonly find a strip with a mix of standard plugs and larger adapters. The challenge is often plug clearance, not strip length. Measure the connected arrangement, keep the enclosure accessible, and do not route the strip cord through the wall to make the box disappear.
At a desk, chargers and device cords can crowd the lid or block ventilation. Arrange the plugs before closing the box, and remove devices you no longer need rather than packing more into a tight space. For a floor-level setup, use a stable location where people will not step on the box or crush its cords.
| Scenario | Main concern | Practical next step |
|---|---|---|
| TV console | Large adapters and limited space behind furniture | Test the connected plugs and lid clearance before placing the box |
| Home office | Many cords crowding the enclosure | Keep vents clear and remove unneeded connections |
| Open living area | Box may be bumped or stepped on | Choose a stable, accessible position allowed by the maker |
| Rental home | Avoiding permanent changes | Use a freestanding or approved surface-mounted box; keep cords out of walls |
For renters, a removable box can hide a strip without cutting into walls. It does not make it safe to conceal the flexible cord behind drywall or under a floor covering. Follow the same product instructions and cord-routing rules as you would in a home you own.
Frequently Asked Questions
These answers cover common decisions when choosing and using a cable box for a power strip. Product instructions and local requirements take priority where they apply. If the strip and enclosure instructions do not support the planned setup, do not enclose the strip.
Can I put a power strip in a cable management box?
Yes, if the enclosure is intended for that use and the strip’s instructions allow it. Follow both products’ requirements for fit and ventilation.
Can I use a regular storage box instead?
Do not assume it is suitable. A closed storage box may restrict heat dissipation and may not provide required access or ventilation.
Can I hide the power strip inside a wall?
No. Do not bury the strip or its flexible cord behind drywall or inside a wall cavity.
Can the strip’s cord pass through a wall opening?
No. NEC 400.12 restricts flexible-cord uses, including running cords through building openings.
How much clearance does a power strip need inside a box?
There is no universal clearance for every setup. Follow the strip and enclosure manufacturers’ requirements.
How do I know whether the box has enough ventilation?
Use the box only if its manufacturer gives instructions suitable for enclosing a power strip. There is no universal airflow value.
Does UL 1363 mean any enclosure is safe?
No. UL 1363 covers relocatable power taps. The strip’s listing does not approve an unrelated box or override either product’s instructions.
Can I close the box lid completely?
Only if the enclosure instructions allow it with the strip inside and the required clearances and ventilation are maintained.
What should I do if the box or strip feels unusually warm?
Stop using the setup and investigate. Do not continue operating it in an enclosure that may be trapping heat.
Can I hide a power strip behind furniture?
Only if it remains accessible, its vents are clear, and the furniture does not press on the box or cords.
