Connecticut-Specific Considerations
- Higher labor costs: Connecticut electrician rates are above the national average. Get a load calculation first to avoid paying for an unnecessary panel upgrade consultation.
- Eversource and UI rebates: Connecticut utilities offer rebates for Level 2 charger installations. Check current program availability with your provider.
- Older housing in New Haven and Hartford: pre-1960 homes may have 100A panels requiring assessment. Fairfield County homes are predominantly 200A.
- Permits required: Connecticut requires electrical permits through local building departments.

"I built ChargeRight because I was tired of seeing homeowners pay $2,000 to $4,500 for panel upgrades that a $49.99 load calculation would have shown they didn't need. The math doesn't lie. Every homeowner deserves to see it before they write a check."
