A Level 2 (240-volt) charger adds roughly 20–40 miles of range per hour for most EVs, versus a few miles per hour from a standard outlet. Installation is one of the most common electrical requests in the area.
Hardwired charger or 240V outlet?
Many chargers can plug into a NEMA 14-50 outlet or be hardwired. Hardwiring often allows higher charging current and avoids outlet wear; outlets are flexible if you might move the charger. Outlets for EV charging generally require GFCI protection under current code, which can add cost.
What drives the price
- Distance from the panel to the parking spot, and whether the wire runs through finished space.
- Panel capacity: a load calculation determines if your panel can take a 40–60A circuit. If not, options include a lower-amp circuit, load management, or a service upgrade.
- Detached garage or outdoor mount: trenching or exterior conduit adds cost.
- Permit and inspection.
Incentives
Federal, state, and utility incentives for home chargers change often, and some have expired. Ask your utility (Delmarva Power or your municipal electric utility) and check current Delaware programs before buying. Don't rely on any incentive figures you see online without confirming them.
