Painting the cover of an electrical panel is a task that many homeowners take on as part of interior renovations or just to spruce things up. However, there are important safety considerations and code requirements to keep in mind before painting an electrical panel cover. Understanding the codes and best practices can help ensure the job is done properly.

What Does the Code Say About Painting Electrical Panels?
The National Electrical Code (NEC) contains regulations for the installation and modification of electrical systems and components, including electrical panels. The NEC does not explicitly prohibit painting the cover of an electrical panel. However, there are a few code requirements that relate to this task:
Accessibility
NEC Article 110.26 requires all electrical equipment to be “readily accessible,” which is defined as having unobstructed access. This means there must be sufficient room in front of the electrical panel to open the door fully and easily access the inside. Painting the cover itself does not violate this code, but the paint job could potentially impact accessibility if not done with care.
Identification
NEC Article 408.4 requires all electrical panelboards to be clearly marked to identify the purpose. This includes voltage, amperage, and other key details. Painting over these important markings could put the panel out of compliance.
Locks
Some local codes prohibit locking or requiring tools to open electrical panel doors. Paint that seals the panel door shut could violate these types of codes.
So in summary, the NEC does not prohibit painting a panel cover itself, but it is essential to consider related codes concerning accessibility, identification, and operation.
Safety Precautions When Painting an Electrical Panel
While painting an electrical panel cover is not expressly forbidden, it is still a project that warrants extra safety steps. Here are some key precautions to take:
Turn Off Power
The power supplying the electrical panel should always be turned off prior to working on or near it. Locate the main breaker or switch that controls the whole panel and turn it to the “off” position.
Remove Cover
Remove the panel cover fully before painting it. It should never be painted while attached and energized. The cover needs to be taken off the panel box and laid on a flat work surface for painting.
Avoid Wet Paint Inside
Use tape, drop cloths, or other protection to prevent any dripping wet paint from getting inside the panel or on the wiring and components. Even after drying, paint could flake off inside over time.
Let Paint Dry
Allow sufficient time for the paint to dry thoroughly before reattaching the cover. Rushing to put it back on while paint is still tacky can cause issues with operation and sealing.
Check Operation
After reattaching the cover, turn the power back on and carefully check that the door opens fully and properly. Make sure the painting did not mechanically obstruct operation.
Following these best practices helps keep electrical panel painting projects code compliant and safe. Never attempt to paint a panel while energized.
Choosing the Right Paint
While the NEC does not specify types of paint, some are better suited than others for use on electrical panels:
Avoid Conductive Paints
Never use paints containing conductive metal particles, such as aluminum or copper. These can cause short circuit hazards. Read labels carefully and only use paints intended for household application.
High-Heat Paint
Look for paints made specifically for high heat areas, such as engine block paints or BBQ and stove paints. Electrical components can generate heat, so high temp paint resists damage.
Gloss or Semi-Gloss
Flat paint tends to show scuffs and marks more easily. Higher sheen paints like gloss or semi-gloss are more durable options for panel covers. The extra shine can also make labels and warnings stand out.
Light Colored Paint
Light paint colors reflect light better, keeping the panel interior brighter and labels easier to see. Darker colors tend to absorb light and can make the cover feel warm.
Primer
For the best adhesion and finish, use an appropriate primer before painting the final coats. Primers also help topcoat paint last longer.
Choosing quality, durable paint designed for high heat, along with proper prep and priming, allows for a long-lasting painted panel cover that stays compliant.
Can You Paint Different Parts of an Electrical Panel?
Beyond just the outer cover, it’s important to understand how paint can and cannot be applied elsewhere on an electrical panel:
Wires and Components
Paint should never be applied to live wires, breakers, bus bars, or other internal components. Even with the power off, painting these poses risks. For one, the paint could flake or rub off over time and expose underlying energized parts. Paint can also potentially act as an insulator and cause components to overheat. Only professionals should paint within the interior of a panel.
Wall Behind Panel
The wall or mounting surface behind the panel can be painted, so long as the work is done carefully to avoid getting paint on the panel or its components. Use drop cloths and tape off the outer panel edges. Avoid conducting spray painting directly at the panel.
Labeling
Painting existing labels or not properly recreating them after painting puts a panel out of compliance. Local codes may also prohibit painting over UL and other approval markings. Check regulations.
Panel Exterior
The outer cabinet and cover of the panel are OK to paint using proper safety procedures and high-quality paint. This allows electrical panels to match changed decor without replacing.
In summary, only the outer surfaces should ever be painted, not wires, bus bars, or other internal components carrying electricity. Take care to also avoid application behind the panel.
Conclusion
Painting over an outdated or worn electrical panel cover can modernize its appearance without the cost of full replacement. This is permitted by electrical code under certain conditions:
– Power to the panel must be turned off prior to painting.
– Paint should be high quality and high heat-resistant.
– Painting must not affect the interior components or impede safe operation.
– All labels and markings must be accurately recreated.
As long as these factors are properly addressed, painting just the outer panel cabinet and cover can be an affordable way to update the look without compromising safety and function. This should only be attempted by qualified homeowners, not renters. Consulting an electrician is advisable if unsure about any details. With proper precautions and planning, a painted panel can both comply with code and keep an electrical system looking its best.
