Hide Breaker Board (Decorative Slatted Screens)
A decorative slatted screen can soften the look of a breaker panel, but it must not hide the panel’s location or delay access. Keep the screen and its supports outside the required electrical working space, preserve the panel door’s full swing, and follow the manufacturer’s ventilation instructions. Confirm measurements against the locally adopted electrical code and your authority having jurisdiction.
A breaker panel is essential, but it can feel out of place in a carefully finished room. A slatted screen can help it sit more quietly in the design. A less cluttered view may make a room feel calmer, though a screen should never trade safe access for a cleaner look.
In my design work, I treat the panel as a fixed point, not something to cover first and measure later. The best screen feels planned with the room, yet leaves the electrical equipment easy to find and reach. The steps below help you make that balance.
Plan the Screen Around the Panel and Adopted Code
Start by recording the panel’s location, size, door swing, and any ventilation instructions. Then check which edition of NFPA 70, also called the National Electrical Code (NEC), your local area has adopted. Local rules and the authority having jurisdiction (AHJ) can affect what is allowed.
Measure before choosing slat depth, frame position, or hardware. A screen that looks open from the room can still stand inside the area needed to work safely at the panel.
Survey the panel before designing
Check the panel label and manufacturer’s instructions. Note the equipment voltage, panel height and width, door hinge side, and where the circuit directory is located. Do not remove the panel cover or touch wiring to gather these details.
Also look for vents or other manufacturer-required openings. There is no universal slat gap or airflow figure for a decorative screen. The panel’s instructions, rather than a guessed spacing, should guide ventilation decisions.
Mark the required space
The NEC sets minimum working-space dimensions for covered electrical equipment. The required width is at least 30 inches (762 mm) or the equipment width, whichever is greater; it does not have to be centered on the equipment. Working-space height is at least 6.5 feet (1,981 mm) or the equipment height, whichever is greater.
Depth depends on voltage to ground and the conditions around the equipment. Use the locally adopted code and have an electrician confirm the right measurement when you are unsure.
| NEC working-space item | Minimum or condition | Design check |
|---|---|---|
| Width | 30 in. (762 mm) or equipment width, whichever is greater | Keep the screen and its supports outside this space |
| Height | 6.5 ft (1,981 mm) or equipment height, whichever is greater | Do not add a top rail that cuts into the required height |
| Depth, 0–150 V to ground | 3 ft (914 mm) | Confirm the measurement point and local code |
| Depth, 151–600 V to ground | 3.5 ft (1,067 mm), 4 ft (1,219 mm), or 5 ft (1,524 mm), depending on conditions | Ask a qualified electrician to identify the applicable table condition |
| Panel door | Must open at least 90° where a hinged door or panel is provided | Check the screen does not stop or narrow the swing |
The depth values for 151–600 volts to ground depend on the conditions listed in NEC Table 110.26(A)(1). Do not select a depth by appearance or assume the shortest one applies. Next step: mark the required area on the floor and wall before laying out the screen.
Preserve Working Space, Door Swing, and Immediate Access
A slatted screen is still an obstruction if it occupies required working space, blocks the panel door, or makes access depend on moving furniture. Open gaps do not change that. Keep the required area clear and make sure the panel can be reached promptly.
A screen that opens may help with access, but it does not automatically make a poor location acceptable. Position the screen and its supports outside required working space, then test how the whole arrangement works in daily use.
Keep access simple
If the screen moves, it should open without tools, keys, or shifting stored items. The opening should give a person clear access to the panel and its circuit directory. Do not put a plant, chair, basket, or other object in the path.
Where a panel door is hinged, confirm it can open at least 90 degrees. Check both doors separately if the panel has more than one. A screen should not collide with the panel door or force someone to hold it aside while opening the equipment.
Keep the dedicated electrical space clear
For indoor equipment, NEC 110.26(E)(1) reserves a dedicated space the width and depth of the equipment, extending from the floor to 6 feet above the equipment or to the structural ceiling, whichever is lower. The code also limits certain foreign systems in this zone.
Ask your electrician or AHJ how the rule applies to the panel and the proposed screen. Do not use the slats as a reason to route unrelated items through the reserved space.
A useful design test is to imagine an urgent repair: can someone identify the panel, reach it, and open it without moving anything? If not, revise the layout before building.
Build and Mount the Slatted Screen Without Loading the Panel
Use a screen frame that stands on its own or attaches to suitable building structure. Never attach it to the panel cover, enclosure, or wiring. Choose hinges, catches, and anchors for the screen’s actual weight and expected use, and add stops so it cannot swing into the panel.
Choose a screen style for the room
A fixed screen can suit a panel that sits outside the required working space and remains easy to reach. A hinged or movable screen may work where it can open at once and does not create a new obstruction. In either case, the panel’s location should remain clear to people who may need it.
| Screen approach | When it may fit | Main risk to check |
|---|---|---|
| Fixed slatted panel | Screen is fully outside required working and dedicated spaces | It may make the panel harder to locate or reach |
| Hinged screen | It can swing open fully, with no key, tool, or moved object needed | The screen may enter the required space or hit the panel door |
| Freestanding screen | It can remain stable and outside the required clearances | It may shift, tip, or be moved into the access path |
Slat direction and finish are design choices, not code safeguards. Wider gaps do not prove adequate airflow, and narrow gaps do not prove the panel is properly ventilated. Follow the equipment maker’s instructions and leave any required vents unobstructed.
Plan for weight and movement
Before installation, decide where the frame’s load will go. Use suitable wall, floor, or ceiling structure as appropriate, rather than relying on the electrical enclosure. For a hinged screen, choose hardware sized for its weight and add a positive stop to limit its travel.
Do not add a lock or a catch that needs a key or tool for access. After mounting, open and close the screen several times. Confirm it stays secure and cannot swing into the panel, its door, or the required clear space.
Verify Clearances, Labels, Operation, and Local Approval
A final check should confirm that the finished screen looks right and still leaves the electrical equipment safe to access. Measure the clearances again with the screen in place, inspect the full door swing, and check the directory and any ventilation openings. Ask the AHJ or a qualified electrician to resolve code questions.
Use a final inspection checklist
- Confirm the panel’s voltage, dimensions, door swing, and manufacturer instructions.
- Measure working-space width, depth, and height against the adopted code.
- Keep the screen and its supports outside the required working space.
- Confirm the dedicated electrical space is addressed.
- Open the screen without a key, tool, or moving stored items.
- Open the panel door at least 90 degrees, where a hinged door is provided.
- Keep the panel location and circuit directory easy to identify.
- Check that the screen is secure and does not block required vents.
- Confirm local approval requirements with the AHJ or a qualified electrician.
Two planning examples
In one common layout, a panel sits beside a hallway door. A fixed screen may look neat, but the door swing and hallway traffic can narrow access. I would first mark the required working space, then test the panel and room doors before choosing a fixed or hinged design.
In another layout, the panel is on a broad wall with open floor space in front. A freestanding or hinged screen may be possible if it stays outside required clearances and opens without delay. These are planning examples, not code approvals; measurements and local review still decide what works.
Frequently Asked Questions
These short answers cover common design and safety questions about slatted screens near breaker panels. Local code adoption, equipment instructions, and the AHJ govern the final decision, so use them to guide planning rather than replace a site review.
Can I put a slatted screen in front of a breaker panel?
Only if it does not occupy required working space or delay access. Keep the screen and its supports outside the required clearance, and ensure the panel remains easy to locate and open. Slats do not make an obstruction acceptable.
How wide should the slat gaps be?
There is no universal code spacing for decorative slats around a breaker panel. Check the panel manufacturer’s ventilation instructions and preserve any required vents. Do not treat wide gaps or a grille-like look as a substitute for clear working space.
Can the screen be fixed in place?
A fixed screen may be suitable only when it stays outside required working and dedicated spaces, does not block the panel door, and leaves the panel readily accessible. If it makes access difficult, choose another layout or omit the screen.
Can I use a hinged screen?
A hinged screen may be considered if it opens immediately without tools, keys, or moving stored objects. It must not swing into the panel or its required clearance. Check its movement and the panel door swing before finalizing the hardware.
How much space must remain in front of the panel?
The NEC working-space depth depends on voltage to ground and the conditions around the equipment. It is 3 feet for 0–150 volts to ground; for 151–600 volts, the table includes 3.5-, 4-, and 5-foot depths. Confirm the correct condition locally.
Does the panel door need to open fully?
Where a hinged equipment door or panel is provided, NEC 110.26(A)(2) requires it to open at least 90 degrees. Make sure the screen, its hinges, and nearby furniture do not prevent that opening.
Can I attach the screen to the panel cover?
No. Mount the screen to suitable building structure, not the panel cover, enclosure, or wiring. Choose anchors and hardware for the screen’s weight, and ensure its frame does not enter required clearances.
Who should confirm the installation?
Ask a qualified electrician to check panel details, clearances, and the applicable code conditions. Contact the AHJ about local requirements or approval. This is especially important when the voltage, working-space depth, or adopted code edition is uncertain.
A slatted screen can make a breaker panel feel more at home in a finished room, but the design must serve access first. Measure the required clearances, keep the screen out of them, and test every door and moving part before installation. When the code conditions are unclear, pause and confirm them with a qualified electrician or the AHJ.
