What is the cost of installing a Level 2 EV charger for two vehicles in one NB garage?

Installing a Level 2 EV charger setup for two vehicles in a New Brunswick garage typically costs $3,500-$8,000 total, depending on your garage's current electrical capacity, distance from the main panel, and whether you choose two separate chargers or one dual-port unit.

The electrical work represents the largest cost component. Most NB garages built before 2020 lack the electrical capacity for EV charging — a Level 2 charger requires a dedicated 240V circuit, typically 40-50 amps per vehicle. For two vehicles, you'll need either two separate 40-amp circuits or one 80-100 amp circuit feeding a dual-port charging station. If your garage currently has basic 15-amp lighting circuits, the electrical upgrade alone runs $2,500-$5,000 including a new sub-panel, circuit breakers, heavy-gauge wire (6 AWG or 4 AWG), and conduit installation.

Distance from your main electrical panel significantly affects cost. If your detached garage is 50+ feet from the house, underground cable installation adds $15-$25 per linear foot. A 75-foot run to a detached garage can add $1,500-$2,500 to the project. Attached garages typically cost less because the wire run is shorter and doesn't require underground burial. Rocky soil conditions common in many NB areas can increase trenching costs for detached garage installations.

Charger hardware costs vary widely based on features and power output. A basic 32-amp Level 2 charger costs $800-$1,500, while smart chargers with WiFi connectivity, scheduling, and load management run $1,200-$2,500 each. Dual-port units that can charge two vehicles simultaneously cost $2,500-$4,500 but require only one electrical circuit and installation, making them cost-effective for two-vehicle households. Tesla Wall Connectors, ChargePoint Home Flex, and Grizzl-E (Canadian-made) are popular choices among NB EV owners.

New Brunswick's cold climate affects charger selection and installation. Choose a charger rated for outdoor use and temperatures down to -40°C — not all residential chargers meet this requirement. The electrical conduit and connections must be weatherproof, and many NB electricians recommend installing the charger inside the garage rather than on an exterior wall to protect it from ice storms and coastal salt air. If installing outside, ensure the charger has a robust enclosure and consider adding a small roof or canopy for weather protection.

Load management becomes critical with two chargers. Most NB homes have 100-amp or 200-amp main electrical services. Two 40-amp EV chargers plus your home's existing electrical loads (heat pump, electric water heater, electric range) can exceed your service capacity during peak usage. Smart chargers with load management features automatically reduce charging power when your home's electrical demand is high, preventing main breaker trips. This technology adds $300-$800 per charger but eliminates the need for expensive electrical service upgrades.

Timing considerations for NB installations include seasonal access and utility coordination. Underground cable installation for detached garages should be completed before ground freeze-up, typically by late November. NB Power may require service upgrades for homes adding significant EV charging loads — coordinate with your electrician early in the planning process, as utility upgrades can take 4-8 weeks to schedule. Winter installations are possible but add complexity and cost for cold-weather materials and heated work areas.

Permit requirements include both electrical permits (always required) and potentially building permits if you're adding a sub-panel or making structural modifications to mount heavy charging equipment. All electrical work must be performed by a licensed electrician and inspected before energizing the circuits.

Budget breakdown for a typical two-vehicle setup: Electrical upgrade and sub-panel ($1,500-$3,000), two dedicated 40-amp circuits ($800-$1,500), underground cable to detached garage if applicable ($1,000-$2,500), two Level 2 chargers ($1,600-$3,000), installation labor ($500-$1,000), permits and inspection ($200-$400). Add 15-25% contingency for unforeseen electrical complications or rock excavation.

Consider future-proofing your installation by running conduit and wire sized for higher amperage than currently needed. EV charging speeds continue to increase, and installing 60-amp circuits now (even with 40-amp chargers) costs only marginally more than upgrading later when faster chargers become standard.
