Before You Buy: 7 Mistakes to Avoid When Choosing an EV Charger

So, you’ve joined the electric vehicle revolution—congratulations! While you’re enjoying the quiet ride and zero emissions, you’ve probably realized that charging at public stations isn’t always convenient. Installing a home EV charger is the next logical step. Over 80% of Canadian EV owners now charge at home, and for good reason. It’s simpler, often cheaper, and ensures your car is ready to go when you are.​

But the process isn't as simple as buying a new toaster. From selecting the right model to ensuring a safe installation, several pitfalls can lead to extra costs, safety hazards, and major headaches.

This guide reveals the seven most common mistakes Canadian EV owners make when selecting a home charger, plus practical steps to avoid each one.

1. Skipping a Professional Electrical Assessment

The Mistake: Many homeowners assume their existing electrical panel can handle an EV charger without checking their home's capacity.

Why It's Dangerous: EV chargers draw significant power. Typically, 30-48 amps for Level 2 charging. Adding this load to an already-stressed electrical system can cause breaker trips, overheating, or fire hazards. Older Canadian homes often have 60-100 amp panels that may already be near capacity from modern appliances.

The Solution:

• Hire a licensed electrician to perform a load assessment
• Check your main service panel's amperage rating
• Verify available breaker space for a dedicated EV circuit
• Consider future electrical needs (second EV, solar panels, heat pump)

Red Flag: Any installer who skips this step or suggests "just plugging into your dryer outlet" is cutting dangerous corners.

2. Choosing the Wrong Charger for Your Vehicle

The Mistake: Buying a charger without confirming compatibility with your EV's charging capabilities and connector type.

Why It Matters: Not all EVs charge at the same speed. A Tesla Model S can accept up to 48 amps, while a Nissan Leaf maxes out at 32 amps. Installing a 48-amp charger for a vehicle that can only use 32 amps wastes money and electrical capacity.

Connector Confusion: Most EVs use the J1772 standard, but Tesla uses NACS (though they include adapters). Some older vehicles use CHAdeMO for DC fast charging.

The Solution:

• Check your vehicle's manual for the maximum AC charging rate
• Verify the correct connector type
• Consider future vehicles you might own
• Choose adjustable amperage chargers (16/32/40/48A) for flexibility

3. Ignoring Permit and Code Requirements

The Mistake: Attempting to install an EV charger without proper permits or code compliance.

Why It's Risky: EV charger installations require permits across Canada. Unpermitted work can:

• Void your home insurance
• Create safety hazards
• Disqualifies you from rebates
• Requires expensive reinstallation

The Solution:

• Always obtain electrical permits before installation
• Use licensed electricians familiar with the Canadian Electrical Code (CEC)
• Ensure inspections are completed and passed
• Keep all documentation for insurance and rebate purposes

Bonus: Some rebate programs require proof of permitted installation, so this step can actually save you money.

4. Poor Charger Placement and Cable Management

The Mistake: Installing the charger in an inconvenient location or failing to plan for proper cable management.

Common Issues:

• The charger is too far from the parking spot
• Cables creating trip hazards
• Inadequate weather protection for outdoor installations
• No consideration for different vehicle charging port locations

The Solution:

• Plan the charger location based on where you actually park
• Consider your EV's charging port location (front vs. rear, left vs. right)
• Ensure adequate cable length (typically 20-25 feet)
• Install proper cable management systems (wall hooks, ceiling retractors)
• Choose weatherproof ratings for Canadian winters (IP65 or higher)

5. Undersized Wiring and Breaker Issues

The Mistake: Using incorrect wire gauges or improperly sized breakers for the charger's electrical load.

The Risk: EV chargers are continuous loads under electrical codes, requiring wiring and breakers sized at 125% of the charger's rating. A 32-amp charger needs a 40-amp breaker and appropriate wire gauge. Undersized components can overheat, creating fire hazards.

• Long cable runs require larger wire gauges to prevent voltage drop
• GFCI protection requirements vary by installation type
• Proper grounding is essential for safety

The Solution: Always use licensed electricians who understand continuous load requirements and can properly size all electrical components.

6. Overlooking Smart Charging Features

The Mistake: Choosing a basic "dumb" charger without considering smart features that can save money and improve convenience.

What You're Missing:

• Time-of-use scheduling: Charge during off-peak hours for 30-50% savings
• Load management: Prevent overloading your electrical panel
• Remote monitoring: Track charging status and energy usage
• Solar integration: Maximize the use of solar power for charging
• Utility program compatibility: Access special EV rates and incentives

The Solution: Invest in a smart charger with Wi-Fi connectivity and scheduling capabilities.

7. Missing Government Rebates and Incentives

The Mistake: Installing an EV charger without researching available rebates and incentives.

What's Available: Canadian provinces offer various rebates:

• British Columbia: Up to $350 for Level 2 chargers through CleanBC programs.
• Alberta: Provincial energy-efficiency rebates and quarterly carbon rebate payments.
• Saskatchewan: Rebates through the federal Canada Carbon Rebate program.
• Manitoba: Up to $150 carbon rebate for individuals; additional EV incentives through federal ZEV programs.
• Ontario: Municipal and utility-based rebates (e.g., Toronto Hydro, Enbridge).
• Quebec: Up to $600 for Level 2 charger installation via Roulez vert.
• New Brunswick: Quarterly federal carbon rebate; some utility EV incentives.
• Nova Scotia: Rebates for EV purchases and installations through Nova Scotia Power.
• Prince Edward Island: Federal rebate participation and local energy grants.
• Newfoundland & Labrador: Quarterly federal rebate; emerging local incentives.
• Yukon: Up to $750 for Level 2 chargers and additional carbon rebates.
• Northwest Territories: 100% rebate on home heating fuel and cost-of-living offsets.
• Nunavut: Covers half of the federal carbon levy, but no rebate program yet.

Federal programs like Natural Resources Canada’s ZEVIP also cover up to 50% of eligible installation costs for home or workplace chargers.

Common Rebate Requirements:

• Licensed electrician installation
• Proper permits and inspections
• Approved charger models
• Pre-approval in some cases
• Specific documentation and receipts

The Solution: Research rebates before purchasing and ensure your installation meets all requirements. Missing these steps can cost you hundreds of dollars in available savings.
