Electrical Panel Clearance Requirements
Electrical panel clearance requirements help provide safe access for inspection, maintenance, service, and emergency operation of electrical equipment.
This page focuses on common electrical panel working space requirements for residential and multifamily electrical panels operating at 1,000 volts nominal or less to ground.
For many standard residential and multifamily electrical panels, the common field answer is:
36 inches of clear working space in front of the panel, 30 inches wide, and 6 feet 6 inches high.
The panel door should be able to open at least 90 degrees, and the working space must be kept clear. The area in front of the panel should not be used for storage.
Always verify the adopted electrical code edition, approved plans, equipment type, and local amendments with the local Authority Having Jurisdiction.
Scope of This Page
This page is focused on typical residential and multifamily electrical panel clearance issues, including:
Dwelling unit electrical panels
Residential service panels
Multifamily unit panels
Garage electrical panels
Meter/main equipment
Subpanels
Common panelboards operating at 1,000 volts nominal or less to ground
Storage or obstruction corrections in front of panels
This page does not cover every commercial, industrial, utility, or high-voltage installation.
Commercial panels that operate at 1,000 volts nominal or less to ground may still use NEC 110.26 working space requirements. However, larger commercial equipment, switchgear, electrical rooms, service rooms, industrial equipment, utility equipment, and equipment over 1,000 volts may have additional or different requirements for working space, access, entrance and egress, dedicated electrical space, and safety clearances.
Do not apply the basic residential panel clearance answer to all commercial or high-voltage equipment without checking the adopted code, approved plans, equipment rating, and AHJ requirements.
Quick Answer
Question:
How much clearance is required in front of an electrical panel?
General Answer:
For many residential and multifamily electrical panels operating at 1,000 volts nominal or less to ground, the common minimum working space is 36 inches in front of the panel, 30 inches wide, and 6 feet 6 inches high. The panel door should open at least 90 degrees, and the working space should not be blocked by storage, appliances, cabinets, shelves, furniture, or other obstructions.
NEC 110.26 — Equipment 1,000 Volts Nominal or Less
National Electrical Code Section 110.26 covers spaces about electrical equipment.
The working space rules in NEC 110.26(A) apply to electrical equipment operating at 1,000 volts nominal or less to ground where the equipment may require examination, adjustment, servicing, or maintenance while energized.
Common residential and multifamily equipment may include:
Electrical panels
Service equipment
Panelboards
Disconnects
Meter/main equipment
Subpanels
Some control equipment
For residential and multifamily inspections, this is the main code section commonly used for electrical panel clearance.
How Much Clearance Is Required in Front of an Electrical Panel?
For most common residential and multifamily panels operating at 1,000 volts nominal or less to ground, the required working space is commonly:
Depth: 36 inches in front of the panel
Width: 30 inches wide or the width of the equipment, whichever is greater
Height: 6 feet 6 inches high or the height of the equipment, whichever is greater
Door opening: Panel doors should open at least 90 degrees
Storage: The working space should not be used for storage
This clearance allows safe access to examine, adjust, service, maintain, and operate the electrical equipment.
Working Space Depth
The working space depth is measured in front of the electrical equipment.
For many typical residential and multifamily electrical panels, the common minimum depth is 36 inches.
However, the required depth can increase depending on the voltage to ground and field condition.
The code uses conditions based on what is opposite the panel, such as:
Exposed live parts on one side and no live or grounded parts on the other side
Grounded parts, concrete, brick, or tile opposite the equipment
Exposed live parts on both sides of the working space
Because of this, 36 inches is the common starting point, but some installations may require more.
Working Space Width
The working space width is commonly required to be at least:
30 inches wide or the width of the equipment, whichever is greater.
The panel does not always have to be centered in the 30-inch working space unless required by the local jurisdiction, approved plans, or field condition.
The important issue is that the required working space is clear and usable.
Working Space Height
The working space height is commonly required to be at least:
6 feet 6 inches high or the height of the equipment, whichever is greater.
Low ceilings, ducts, piping, shelves, cabinets, or other obstructions may create inspection issues if they interfere with the required working space.
Panel Door Opening
The electrical panel door or hinged cover should be able to open at least 90 degrees.
If a wall, cabinet, appliance, shelf, or other obstruction prevents the panel door from opening properly, it may be a correction.
Clear Space — No Storage
The required working space should not be used for storage.
Common problems include:
Boxes stored in front of the panel
Shelving installed too close
Workbench blocking access
Washer or dryer blocking access
Water heater blocking access
Furnace blocking access
Cabinets built around the panel
Furniture blocking the panel
Tools or material stored in the working space
Electrical panels must remain accessible.
California Electrical Code Panel Clearance
In California, electrical panel clearance is reviewed under the California Electrical Code, Title 24, Part 3, along with local amendments.
California jurisdictions commonly use Section 110.26 for working space around electrical equipment operating at 1,000 volts nominal or less to ground.
Always verify:
Adopted California Electrical Code edition
Local amendments
Approved plans
Utility requirements
Manufacturer installation instructions
Local inspection policies
Electrical Panel in a Garage
Electrical panels are often located in garages.
Common garage clearance problems include:
Storage boxes
Shelving
Work benches
Tools
Appliances
Water heaters
Laundry equipment
Vehicles
Cabinets
The required working space must remain clear even if the garage is used for storage.
Electrical Panel in a Closet
Electrical panels may not be allowed in certain closet locations, especially clothes closets.
A closet location can create a correction even if the panel appears to have enough front clearance.
Always verify the adopted electrical code and local amendments before installing or approving a panel in a closet.
Electrical Panel Near a Water Heater or Furnace
Electrical panels are sometimes installed too close to water heaters, furnaces, or mechanical equipment.
The issue is whether the electrical panel still has:
Required working space depth
Required working space width
Required working space height
Clear access
Door opening clearance
Dedicated electrical space where required
A water heater, furnace, or appliance should not block the required working space in front of the panel.
Dedicated Electrical Space
Some electrical equipment also requires dedicated electrical space.
Dedicated electrical space may restrict piping, ducts, leak sources, or unrelated equipment above or around the electrical equipment.
This is separate from the working space in front of the panel.
Always verify the adopted code, approved plans, and local inspection requirements.
Common Electrical Panel Clearance Corrections
Common inspection corrections include:
Less than 36 inches of working space in front of the panel
Less than 30 inches of working space width
Less than 6 feet 6 inches of headroom
Panel door cannot open at least 90 degrees
Storage in front of the panel
Cabinet, shelf, or workbench blocking access
Water heater, furnace, washer, dryer, or appliance blocking the panel
Panel located in a clothes closet or prohibited location
Panel access blocked by locked gate, locked room, or obstruction
Equipment installed too close to a wall or corner
Dedicated electrical space obstructed
Panel not installed per approved plans
Unsafe or restricted access to service equipment
Example Inspection Question
Question:
There are storage boxes in front of an electrical panel. Is this a code issue?
General Answer:
Yes. Electrical panel working space must be kept clear. For many residential and multifamily panels operating at 1,000 volts nominal or less to ground, the common required working space is 36 inches in front of the panel, 30 inches wide, and 6 feet 6 inches high. Storage boxes, shelving, appliances, furniture, or other obstructions in this space may require correction.
