What is a Level 2 EV Charger?
Section Subtitle
A Level 2 EV charger operates at 240V, significantly faster than a standard 120V Level 1 charger. With a Level 2 charger, most EVs can be fully charged in 4 to 8 hours, compared to 20+ hours with a Level 1 charger.
Benefits of Level 2 Charging:
✔ 5X Faster Charging than a standard home outlet
✔ More Energy Efficient, reducing long-term electricity costs
✔ Compatible with All EV Models, including Tesla, Ford, Rivian, Nissan, and more
To install a Level 2 charger, you’ll need either a dedicated NEMA 240V outlet or a hardwired connection. Let’s compare the two options.
Hardwired vs. NEMA Outlet for Level 2 EV Chargers:
Which One Should You Choose?
Hardwired Installation
A hardwired EV charger is directly connected to your home’s electrical system without a plug, providing better durability and compliance with some local electrical codes.
Pros:
+ Lower Installation Cost – Less materials need.
+ Safer & More Durable – No loose plugs, reducing fire risks.
+ More Features – Many smart chargers (Tesla Wall Connector, Enel X, ChargePoint, etc,.) require hardwiring.
Cons:
- Less Flexibility – Not portable if you move.
NEMA 14-50 or NEMA 6-50 Outlet Installation
A NEMA 14-50 or NEMA 6-50 outlet is a 240V plug that allows you to connect a portable Level 2 charger.
Pros:
+ Flexibility – Easily unplug the charger or take it with you if you move.
+ Compatible with Many Brands – Tesla Mobile Connector, ChargePoint, JuiceBox, Grizzl-E, etc.
Cons:
- Slightly Less Reliable – Outlet wear over time may require replacement.
Which Installation is Right for You?
If you want flexible setup, a NEMA outlet is a great option.
But if you prefer a cost-effective and long-term solution, a hardwired EV charger is the better choice.
Considerations Before Your EV Charger Installation
Before installing a Level 2 EV charger, it’s important to assess your home’s electrical capacity and setup.
Here are the key factors to consider:
Do You Have Space in Your Electrical Panel?
A Level 2 EV charger typically requires a dedicated 240V circuit (40A–60A).
Your electrical panel must have an open breaker slot to accommodate this new circuit.
If your panel is full, you may need a tandem breaker, panel upgrade or subpanel installation, which we can assess during your free estimate.
Where Will You Install the Charger?
Consider whether the charger will be installed indoors (garage) or outdoors (driveway). The charger should be positioned close to where you park for easy plug-in access.
