EV Charger Installation for Portland Homes & Businesses
Casco Bay Electric installs EV chargers for residential and commercial properties throughout Portland and Southern Maine, handling everything from site assessment and electrical planning to permitting, installation, final inspection, and activation. With experience installing hundreds of chargers, from Level 2 residential units to commercial fast-charging systems, our electricians properly size and protect each circuit to support safe, reliable, long-term performance.
EV charger installation requires more than running a wire from the panel to a wall. We evaluate your vehicle's charging needs, available electrical capacity, circuit requirements, and local permitting requirements to ensure the system is built correctly. Whether you're upgrading to a 240V Level 2 charger that can cut home charging from 24+ hours to roughly 4–10 hours or developing commercial charging infrastructure, we build the electrical system to support your needs now and in the future.
Types of EV Charger Installation Services We Provide
Residential Level 2 Charger Installation
Most homeowners need a 240V Level 2 charger, which cuts charging time dramatically compared to standard outlets. We assess your panel's available capacity, run dedicated circuits (usually 40–60 amps), install the charger per manufacturer specs and code, and handle all permitting and inspection. Installation typically takes one day, though panel upgrades (if needed) may add time. We work with all major charger brands and can recommend hardware based on your vehicle, usage, and budget.
Commercial and Fleet EV Charging
Businesses, municipalities, and fleet operators need chargers that handle multiple vehicles, operate reliably in high-use environments, and integrate with site electrical systems. We design and install Level 2 networks, DC fast-charging systems, and custom charging infrastructure for hotels, marinas, municipal fleets, and manufacturing facilities. This includes load management (so chargers don't overload your service), monitoring systems, and redundancy for mission-critical applications.
Service Panel Upgrades for EV Charging
Older homes often have 100-amp panels that can't safely support a dedicated EV charger circuit. We upgrade electric panels to 150-amp or 200-amp service, bringing your home up to modern code and creating the capacity your charger needs. This is one of our core services — we've upgraded hundreds of Maine homes — and we handle permitting, inspection, and utility coordination seamlessly.
Why Portland Chooses Casco Bay Electric
Licensed Master Electricians Overseeing Every Install
Our work is overseen by licensed master electricians in Maine. Every EV charger installation meets or exceeds the National Electrical Code and local permit requirements. You're not getting an apprentice or a contractor cutting corners — you're getting experienced professionals who understand the electrical load implications and long-term safety of your charger.
We Pick Up the Phone
We staff local offices in Portland, Lewiston, York, and Arundel with estimators and electricians who can talk you through your options today, not next week. If you call with questions about your panel capacity, charger options, or timeline, you reach a real person who can move on your project immediately.
Fast, Flexible Scheduling
EV charger installations are often time-sensitive — you want your charger operational before winter, or before a commercial site opens. We handle 100–130 jobs per week across our service area and can mobilize quickly for new projects. We also take on last-minute work and offer 24/7 emergency service if a charger fails or needs urgent attention.
Fully Equipped In-House
We own excavators, bucket trucks, and thermal imaging equipment. If your charger install requires underground conduit, trenching, or high-access work, we do it in-house without scheduling delays or subcontractor markups. That means faster completion and better cost control for you.
Transparent Permitting and Inspection
Charger installations require electrical permits and final inspection in Portland. We pull permits on your behalf, coordinate with the city, and ensure your installation passes inspection the first time. No surprises, no rework.
Warranty and Ongoing Support
We stand behind every installation with a warranty on our labor. If something goes wrong with the electrical work, we fix it. We're also here for service calls, troubleshooting, and upgrades as your charging needs evolve.
