Can You Install an EV Charger Outside? What Centennial, CO Homeowners Should Know
If you own an electric vehicle but don't have a garage, you may be wondering whether you can install an EV charging station outside your home. The good news is that many electric vehicle chargers are designed for outdoor use, making it possible to charge your vehicle conveniently in your driveway or another suitable parking area.
For homeowners in Centennial, Parker, and surrounding Colorado communities, outdoor EV charger installation can be a practical solution. However, Colorado's changing weather conditions, electrical requirements, and charger placement all need to be considered.
At Block Electric, we provide professional residential and commercial EV charger installation throughout the Denver metro area. Here's what you should know before installing an outdoor charging station.
Can an EV Charger Be Installed Outdoors?
Yes. Many Level 2 EV chargers are designed for both indoor and outdoor installation, provided the equipment is appropriately rated and installed according to the manufacturer's instructions.
Outdoor charging stations can be mounted on an exterior wall, installed on a suitable pedestal, or positioned near a driveway or parking space.
Common outdoor EV charger installation locations include:
Exterior garage walls
Driveways and parking areas
Carports
Exterior walls near dedicated parking spaces
Freestanding charging pedestals
Residential and commercial parking areas
The best installation location depends on your home's electrical system, available parking space, charger cable length, and exposure to weather.
A licensed electrician can help determine a safe and convenient location for your charging equipment.
Are Outdoor EV Chargers Safe in Colorado Weather?
Colorado homeowners experience a wide range of weather conditions, including snow, rain, freezing temperatures, intense sunlight, and summer thunderstorms.
Fortunately, many modern EV charging stations are designed to withstand outdoor conditions.
However, not every charger is approved for outdoor installation.
When selecting outdoor charging equipment, consider the following factors.
Weather-Resistant Charging Equipment
Choose an EV charger specifically rated for outdoor use. Look for a suitable NEMA enclosure rating, such as NEMA 3R or NEMA 4, or another manufacturer-approved outdoor protection rating.
The appropriate rating depends on the installation location and expected exposure.
Snow and Ice Exposure
Outdoor EV chargers should be positioned to minimize snow accumulation and prevent charging cables and connectors from sitting in standing water or ice.
Charging equipment should also be installed where it can be accessed safely during winter conditions.
Temperature Considerations
Most outdoor-rated EV chargers are designed to operate within a specified temperature range.
Before purchasing a charger, review the manufacturer's operating temperature specifications to ensure the equipment is suitable for Colorado's climate.
Proper Electrical Protection
Outdoor EV charger installations require appropriate wiring, grounding, circuit protection, and weather-resistant electrical components.
Electrical requirements vary depending on the charging equipment, installation method, and applicable electrical codes.
Professional installation helps ensure your outdoor charging station is installed correctly.
Where Should You Install an Outdoor EV Charger?
Choosing the right location is one of the most important decisions when installing an outdoor EV charging station.
A convenient location can make daily charging easier while helping protect the equipment from unnecessary exposure or damage.
Exterior Garage Wall
Mounting a charger on an exterior garage wall is a popular option for homeowners who park in their driveway.
This location may provide relatively convenient access to the home's electrical system while allowing the charging cable to reach the vehicle.
Driveway Charging Station
For homes without garages, an outdoor charger can sometimes be installed on an exterior wall near the driveway.
The location should allow the charging cable to reach the vehicle without creating a tripping hazard or obstructing walkways.
Freestanding EV Charger Pedestal
If a wall-mounted charger isn't practical, a freestanding pedestal may be an option.
Pedestal installations can be useful for detached parking spaces, longer driveways, and certain commercial properties.
These installations may require underground electrical wiring, trenching, and additional protective measures.
Can You Install a Tesla Wall Connector Outside?
Yes. Tesla Wall Connectors are designed for indoor and outdoor installation when installed according to the manufacturer's specifications.
A Tesla Wall Connector can be a convenient option for homeowners who park their vehicles outside or want a permanent charging station near their driveway.
Benefits of a Tesla Wall Connector include:
Weather-resistant equipment designed for approved outdoor installations
Convenient Level 2 home charging
A permanently mounted charging station
Wi-Fi connectivity and compatible charging management features
Charging options for compatible Tesla and non-Tesla vehicles

Our electricians can evaluate your electrical system and help determine an appropriate outdoor installation location.
Does an Outdoor EV Charger Need a Dedicated Circuit?
Most residential Level 2 EV chargers require an appropriately sized dedicated electrical circuit.
EV charging equipment can place a substantial continuous load on your home's electrical system, making proper circuit sizing and electrical load calculations essential.
Before installing an outdoor EV charger, an electrician should evaluate:
Your home's existing electrical service capacity
Available space in the electrical panel
The charger's power requirements
The distance from the panel to the charging location
Wiring and conduit requirements
Grounding and circuit protection
Whether electrical upgrades are necessary
Some homes can accommodate an EV charger without upgrading the electrical panel. Others may need additional electrical capacity or an approved load-management solution.
Block Electric can evaluate your electrical system and recommend an installation approach based on your home's needs.
Is a Hardwired EV Charger Better for Outdoor Installation?
For many outdoor installations, a hardwired Level 2 EV charger is a practical choice.
Hardwired charging stations connect directly to a dedicated electrical circuit rather than plugging into a receptacle.
Potential advantages include:
Fewer exposed electrical connections
No plug-and-receptacle connection at the charging station
A permanent installation
Compatibility with many outdoor-rated charging stations
Potentially higher charging amperage when supported by the equipment and electrical system
Some plug-in EV chargers are also approved for outdoor use, but the receptacle, enclosure, circuit protection, and charging equipment must all be suitable for the installation.
A licensed electrician can help determine which option is appropriate for your property.

How Much Does Outdoor EV Charger Installation Cost?
Outdoor EV charger installation costs vary depending on the electrical system, charging equipment, and installation location.
Factors that can affect the total cost include:
Distance between the electrical panel and charger
Wall-mounted versus pedestal installation
Electrical wiring and conduit requirements
Underground wiring or trenching
Charger equipment and weather protection
Electrical panel upgrades, if needed
Permits and inspection requirements
A charger installed on an exterior garage wall near the electrical panel may require less electrical work than a freestanding charger located farther from the home.
Block Electric provides complimentary estimates to help homeowners understand their installation options and anticipated costs.
