Hide Electrical Gear & Fuse Box (Slatted Wood Cover)
A slatted-wood screen can make an electrical panel less visible, but it must remain separate from the equipment and open or come away readily. Plan it outside required working space, preserve the panel door’s full swing, and follow the locally adopted electrical code and manufacturer’s instructions. Slat gaps alone do not prove that a cover is safe.
A breaker panel can interrupt an otherwise calm room, so a wood screen may seem like a simple fix. The hard part is not choosing slat width or stain. It is keeping the panel easy to reach and safe to work on, even after the screen is installed.
I plan these screens as separate architectural features, never as additions to the electrical enclosure. The measurements and checks below can help you develop a design, but local code adoption, panel instructions, and site conditions matter. Ask a qualified electrician or local authority to review anything uncertain before building.
Plan the Screen Around the Panel and Adopted Code
A decorative screen should hide the panel from view without becoming a barrier to its use. Start by identifying the equipment and its instructions, then check the electrical rules adopted in your area. The National Electrical Code (NEC) references below are useful planning checks, not a substitute for local approval.
First, identify whether you are covering a breaker panel, disconnect, or other electrical equipment. Find the panel label and manufacturer instructions, and note any vents, warning labels, handles, hinges, or stated clearance needs. Do not remove the panel cover or deadfront to investigate; that can expose live parts.
Next, confirm which code edition your local jurisdiction has adopted and whether an authority having jurisdiction (AHJ), such as a building inspector, needs to approve the work. Requirements can depend on the equipment, location, and conditions around it. The applicable code edition and equipment instructions should guide the final layout.
Measure before you draw the screen. Record the panel’s width and height, how its door opens, and the clear floor area in front of it. Mark proposed screen edges and the panel door’s full swing with painter’s tape. This helps reveal conflicts before you select slat spacing or build a frame.
Do not attach the screen to the panel, its enclosure, conduit, or wiring. The cover must not hide labels or operating handles, block openings, or carry weight on the electrical equipment. Next step: confirm the local rules and manufacturer instructions before choosing a screen location.
Preserve Working Space, Door Swing, and Dedicated Space
Electrical working space is the clear area needed to approach and service equipment. Under the cited NEC provisions, its width, height, and depth depend on the equipment and conditions. A decorative screen must not occupy that required space, obstruct the panel door, or interfere with applicable dedicated-space rules.
Use these NEC 110.26 figures as planning checks, then verify the locally adopted code and site conditions. The width under 110.26(A)(2) is at least 30 inches (762 mm) or the equipment width, whichever is greater. The space may be offset from the panel’s centerline, but it must still meet the applicable requirements.
The height under 110.26(A)(3) is at least 6 feet 6 inches (1.98 m) or the equipment height, whichever is greater, measured from the floor or grade. Depth under 110.26(A)(1) depends on voltage to ground and the conditions in Table 110.26(A)(1):
| Equipment voltage to ground | NEC working-space depth in the stated conditions |
|---|---|
| 0–150 V | 3 ft (914 mm) |
| 151–600 V, Condition 1 | 3 ft 6 in. (1.07 m) |
| 151–600 V, Condition 2 | 4 ft (1.22 m) |
| 151–600 V, Condition 3 | 5 ft (1.52 m) |
The applicable condition depends on the opposing surfaces and live parts. Do not select a depth by guesswork; have the voltage and condition confirmed against the adopted code. Panel doors or equipment panels must open at least 90 degrees under 110.26(A)(2). The decorative screen must also open or come away without tools, and furniture or stored items must not block access.
Where NEC 110.26(E) applies, dedicated space extends from the equipment footprint to 6 feet above the equipment or to the structural ceiling, whichever is lower. Keep foreign systems out of that space as required. A screen or its framing must not compromise it.
A screen can be visually open yet still interfere with service. Check where its frame, hinges, and open leaf sit, not only where the slats appear when closed. Next step: mark the required working-space boundaries and door swing before fixing the screen’s position.
Frame and Finish Without Loading or Altering the Equipment
A non-load-bearing screen is a separate structure supported by the building, not by electrical equipment. Its frame, hinges, and latches should carry the finished screen’s weight while leaving the panel untouched. Careful placement also helps prevent fasteners from striking concealed wires or other services.
Set the screen wholly outside the required working space. If it swings, confirm that the open screen does not enter that space or obstruct the panel door. A removable screen may suit a tight layout, but it must be readily removable without tools and must not depend on stored items being moved first.
Support the frame from suitable building framing. Before drilling, consider what may be behind the wall and how services run. Do not drill into or fasten to the panel enclosure, deadfront, conduit, or wiring. If you cannot locate safe fixing points, pause and ask a qualified professional to assess the wall.
Choose hinges and latches for the screen’s actual finished weight and size. Provide a way to hold it securely open, so it cannot swing back across the panel while someone needs access. Slats can create a light, architectural appearance, but they do not replace required clearances.
There is no universal safe slat gap or cover-to-panel distance. The NEC does not set a general airflow rate or slat-spacing rule for decorative screens. Follow the panel manufacturer’s ventilation and access instructions. Never cover vents, labels, hinges, handles, or other openings.
Do not paint the panel enclosure or cover it with wood, fabric, or another finish. Keep the screen independent, and make sure its frame does not touch or load the equipment. Next step: have the support points, screen movement, and equipment instructions reviewed before installation.
Verify Access, Clearances, and Manufacturer Requirements
A final check confirms that the screen works in real use, not only in a drawing. Open the decorative cover and panel door fully, confirm required clearances remain clear, and look for contact with equipment, blocked labels, or restricted airflow. Resolve any issue before the screen is considered complete.
Before installation, check the panel’s make and model, voltage information, door swing, and manufacturer instructions. Confirm the locally adopted code edition and mark the required working-space boundaries. If the equipment’s voltage, condition, or ventilation needs are unclear, get help rather than assuming a standard dimension applies.
After the frame is mounted, test its movement. The cover should open or be removed immediately and without tools; it should not jam against the panel door or require someone to shift furniture. When open, it needs positive retention so it stays out of the way.
Then open the panel door at least 90 degrees and compare the actual clearance with your marked layout and the applicable code requirements. Check that no slat or frame blocks the equipment, its labels, vents, or operating handles. Ensure the cover does not touch the enclosure or hang from it.
Next step: take photos of the screen open and closed, and ask the electrician or AHJ to review the final condition if required or if any clearance is uncertain.
Design Case Studies: Where Slatted Screens Can Go Wrong
These illustrative design cases show how the same screen idea can work differently based on the panel location. They are planning examples, not reports of specific installations or proof that a layout meets local code. Apply the measurements and checks to the actual equipment and site.
Case 1: Panel on a broad hallway wall. A screen can sit beside or in front of the panel only if it remains outside the required working space and does not impede the panel door. A hinged leaf that lands across the access area may look tidy when closed but fail in use. Mark the swing and working-space boundaries first.
Case 2: Panel in a narrow utility area. A screen may leave too little room for access if it projects into the required depth or has a wide open leaf. A removable cover could be considered only if it comes away readily, without tools, and is supported independently. Check the complete route to the panel, not just the closed position.
Case 3: Panel with visible vents or airflow instructions. Open slats do not automatically provide enough airflow. If the panel has vents or its instructions call for free airflow, do not enclose it until the design has been reviewed. There is no generic slat gap or airflow value that overrides those instructions.
In each case, the design decision follows the equipment and the clearances, not a preferred screen style. Next step: test the proposed layout at full size before ordering materials.
Quick Comparison: Fixed, Hinged, or Removable Screen
The best screen type depends on the room, the panel door, and available clear space. This comparison helps narrow the design, but it does not establish code compliance. Every option must preserve required working space and ready access.
| Screen approach | When it may suit the layout | Main check |
|---|---|---|
| Fixed slatted screen | Only where it sits entirely outside required working space and does not prevent ready access | A fixed barrier can obstruct access even if the panel door itself opens |
| Hinged screen | Where the open leaf can stay clear of the work area and panel door | Confirm full swing, secure open position, and no contact with equipment |
| Readily removable screen | Where a fixed or swinging panel would obstruct access | It must come away without tools and without moving stored items |
Do not use a locked cover or fixed cabinet where it blocks ready access or occupies required working space. A screen should not turn an accessible panel into a storage nook or a task that requires extra steps. Next step: choose the option that clears the measured space in both its closed and open positions.
Frequently Asked Questions
These answers address common design questions about slatted screens and electrical panels. Local code adoption and the manufacturer’s instructions control the final details. When either is unclear, seek review before installing a cover.
Can I put a slatted wood cover over my breaker panel?
You can consider a separate screen if it does not block required working space, door swing, access, labels, vents, or manufacturer-required ventilation. Confirm the layout against local code.
How much space must remain in front of a panel?
NEC 110.26 sets working depth by voltage to ground and conditions. The listed values include 3 feet for 0–150 V, and 3 feet 6 inches, 4 feet, or 5 feet for 151–600 V under Conditions 1, 2, or 3. Verify which applies locally.
How wide must the working space be?
The cited NEC minimum is 30 inches (762 mm) or the equipment width, whichever is greater. The space may be offset from the equipment centerline.
How tall must the clear area be?
The cited minimum is 6 feet 6 inches (1.98 m) or the equipment height, whichever is greater, measured from floor or grade.
Can the screen be hinged?
Yes, if it opens without tools, stays clear of the required working space, and does not obstruct the panel door. The equipment door must open at least 90 degrees.
Is there a required gap between the wood slats?
There is no universal NEC slat-gap or airflow value for decorative screens. Follow the equipment instructions and do not cover vents or openings.
Can I attach the screen to the electrical panel?
No. Support it from building framing, not the panel, enclosure, conduit, or wiring. Do not drill into or alter electrical equipment.
Can a screen occupy the space above the panel?
Where NEC 110.26(E) applies, dedicated space extends from the equipment footprint to 6 feet above the equipment or the structural ceiling, whichever is lower. Check the adopted code and keep prohibited foreign systems out.
A well-planned slatted screen makes electrical gear less prominent without making it harder to reach. Measure the full working space, follow the panel instructions, and keep the screen independent of the equipment. If a dimension, airflow need, or code condition is uncertain, have the layout checked before building.
