Before you install a home charger in Connecticut

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Connecticut electrician to quote the install before this math becomes a real decision.
