Planning to install an EV charger in your Northern New Jersey home? Discover why an electrical service upgrade might be necessary to support your new vehicle safely.
Do You Need a Service Upgrade for an EV Charger?
In many cases, yes. Installing a Level 2 electric vehicle charger adds a significant load to your home's electrical system. For many older homes in Bergen County, the existing electrical service—often rated at 100 amps—may not have enough remaining capacity to handle the continuous high-power demand of an EV charger without risking tripped breakers or system strain.
Understanding Your Home’s Electrical Capacity
Your home's electrical service is the gateway for power from the utility to your breaker panel. If your home was built decades ago, it was likely designed to handle lighting, small appliances, and a modest HVAC system. Today, however, our homes are taxed with central air conditioning, high-end kitchens, home offices, and now, EV charging.
When a licensed electrician assesses your panel for an EV installation, they perform a load calculation. This formula determines if your current service can handle the addition of a dedicated circuit for an EV charger. If the calculation shows you are near or over your capacity, a service upgrade to 200 amps is the recommended path to ensure safety and code compliance.
Why Northern New Jersey Homes Need Upgrades
Bergen County features a unique blend of historic housing stock and newer luxury builds. Homes in towns like Ridgewood, Englewood, and Teaneck often rely on older infrastructure that was never meant for the modern "electrified" lifestyle. As more residents in Paramus, Franklin Lakes, and Mahwah make the switch to electric vehicles, the demand on our local power grid and individual home panels has increased exponentially.
The Benefits of Upgrading to 200 Amps
- Future-Proofing: A 200-amp service provides enough "headroom" to add future upgrades like heat pumps, solar arrays, or backup generators.
- Safety: Eliminating the risk of overloading your main breaker prevents fire hazards and frequent power outages.
- Peace of Mind: Knowing your home can support simultaneous appliance usage—like running your dryer while your car is charging—without issue.

Frequently Asked Questions
1. How do I know if I have a 100-amp or 200-amp service? You can usually check the main breaker switch at the top of your electrical panel. It will be labeled with the total amperage capacity.
2. Is a permit required for EV charger installation? Yes, most municipalities in Northern New Jersey require electrical permits for dedicated circuits and EV charger installations.
3. Can I use a regular outlet to charge my EV? You can use a Level 1 (120V) outlet, but it is extremely slow. A Level 2 charger requires a 240V dedicated circuit.
4. Does an upgrade increase my home value? Yes, a modern 200-amp electrical panel is an attractive feature for future homebuyers who are likely looking for EV-ready properties.
5. How long does a service upgrade take? A standard service upgrade typically takes one full day, including coordination with your utility provider for power disconnection and reconnection.
6. Does Vaccarella Electric handle the utility company coordination? We guide you through the process, though your utility provider must perform the physical wire connection from the street to your home.
7. What if I have a subpanel? Our electricians will assess whether your main panel or subpanel is the best location for your new dedicated EV circuit.
