Understanding Electrical Panel Height: What the Code Really Says
Are you installing a new electrical panel in your home? Or perhaps you’re hiring an electrician and wondering what the proper panel height should be? You’re not alone. Electrical code requirements for panel height can be a bit confusing, so let’s break them down clearly.
What We’re Covering
Today, we’re discussing electrical panel code heights—specifically the height of an electrical panel and where it should be mounted according to code. While requirements may vary slightly between Canada and the U.S., they’re quite similar across North America. Always check with your local electrician and inspection department for final confirmation.
The Basics: Panel Types and Layout
For reference, we’re working with a Square D 40/80 main circuit panel rated at 200 amps. This panel includes:
- A main breaker at the top
- Incoming wires from the utility entering at the top
- A breaker compartment that extends from the main breaker down to the bottom, where individual branch circuit breakers are located
Code Requirements for Height
On new construction, the maximum height allowed for the top breaker is 67 inches (5 ft 7 in) from the floor.
⚠️ Note: This refers to the top breaker, not the top of the enclosure itself.
Because different manufacturers design panels to be mounted in various orientations (right-side up, upside down, or even sideways), what matters is the position of that top breaker—not the panel’s shape or layout. Always double-check the manufacturer’s label to confirm allowed mounting orientations.
Orientation Examples
- Upside Down Mounting: The main breaker is at the bottom. The highest branch breaker becomes the new “top breaker,” and it must still be within that 67-inch limit.
- Sideways Mounting: If allowed, the highest reachable breaker along the side must not exceed 67 inches from the floor.
Panel Size Matters
Not all panels are created equal. Larger residential or commercial panels—like a 60/120 circuit unit—can be 6 or even 7 feet tall. That means you’ll have to mount the entire panel lower to stay within the 67-inch rule for the top breaker.
In these cases, the bottom of the panel may end up very low, which isn’t ideal either. Always consider the total size of the panel when planning your installation.
Exceptions for Renovations
The 67-inch rule applies to new builds. If you’re doing a renovation or retrofit, there’s often a little more flexibility. Inspectors typically use their discretion in older homes—especially where ceiling height may be limited (e.g., old basements under 7 feet tall).
While the code requires 2.1 meters (about 7 feet) of head clearance and 1 meter (roughly 3.3 feet) of working space in front of the panel, an inspector may allow some leniency in tight spaces as long as the area is safe and accessible.
Minimum Height Considerations
While there’s no official minimum height, you generally shouldn’t mount a panel too low. Panels placed too close to the floor can be accessed by children or easily obstructed.
As a good rule of thumb, aim to mount the panel at eye level, which conveniently aligns with the 67-inch maximum height for the top breaker.
Final Thoughts
Every installation is unique, but here’s a quick checklist to keep in mind:
- ✅ Max height to top breaker: 67 inches
- ✅ Maintain 3.3 feet clearance in front of the panel
- ✅ Ensure 7 feet of vertical clearance above
- ✅ Adjust panel position based on its total size
- ✅ Verify orientation and mount per manufacturer’s specs
- ✅ Consult your local inspector, especially on retrofits
Always work with a licensed electrician and follow your local electrical code for best results.
