Typical Challenges for Detached-Garage Chargers
Detached structures introduce additional electrical and construction considerations compared to attached garages.
Long Distance from Panel
The main panel is often in the house, while the charger location is in a separate structure, requiring long cable and conduit runs.
Underground Trenching
Wiring typically needs to be buried between structures, with proper depth, conduit, and protection to meet code and remain durable.
Subpanel Requirements
Many detached garages benefit from a small subpanel to support the charger and future loads such as lighting, tools, or heaters.
Driveway and Landscaping
Trench routes must consider driveways, walkways, irrigation, and existing underground services to avoid damage and extra cost.
Outdoor and Weather Exposure
Equipment and conduit must be rated for outdoor use and installed to handle Edmonton’s climate, including snow, ice, and temperature swings.
Future-Proofing
Properly sizing conduit and circuits now can support higher-power chargers or additional equipment later without re-trenching.
How We Handle Detached-Garage Installations
A structured approach to keep the project safe, code-compliant, and as low-impact as possible on your property.
Route assessment
We review the best path from the house panel to the garage, considering distance, obstacles, and existing underground services.
Trenching and conduit
We install underground conduit at code-compliant depths, with appropriate protection where the run crosses driveways or high-traffic areas.
Wiring and subpanel
We pull the appropriate conductors and, where needed, install a small subpanel in the detached structure to support the charger and future loads.
Charger installation
The EV charger is mounted, wired, and tested, with all connections protected for outdoor and cold-weather operation.
Permit and inspection
We obtain the electrical permit and coordinate inspections so the installation is fully approved and documented.
What We Need From You
The more information you can share up front, the more accurate your quote will be.
- Photos of the house panel and its location.
- Photos of the detached garage and proposed charger location.
- Approximate distance between the house and garage.
- Details about the driveway, landscaping, and any known underground services.
- Your vehicle details and preferred charging speed (if known).
Photo checklist
- Electrical panel (front cover removed if safe).
- Exterior of the house where the trench could start.
- Detached garage exterior and interior wall where the charger could mount.
- Driveway or path between house and garage.
