Frequently asked questions

How much does a 100A to 200A panel upgrade cost in Connecticut?

In Connecticut, a 100A to 200A panel upgrade typically runs $2,196–$5,490 installed. The work includes a new 200A main breaker, meter base, service-entrance conductors, and utility coordination. Use the calculator above to refine for your existing panel and install difficulty.

Is a panel upgrade necessary for an EV charger or heat pump in Connecticut?

Not always. NEC 220.83 load calculations frequently show a 100A panel handles a heat pump + EV charger + induction range if existing loads are modest. A smart load-management device ($500 to $1,500) often replaces a $4,000 upgrade by scheduling large loads so the home never exceeds the existing service capacity. Connecticut licensed electricians can run the load calc for $100 to $300.

What permits and rebates apply in Connecticut?

Permit fees in Connecticut average about $380 for a residential service upgrade. The federal 25C credit expired Dec 31 2025 under OBBBA, so federal credits no longer apply to panel work placed in service in 2026. The calculator surfaces 2 programs for Connecticut.

How long does the work take in Connecticut?

A typical 100A to 200A service upgrade is a one-day job, but power is off for 4 to 8 hours during the cutover. If the utility has to replace the service drop or relocate the meter, the calendar can stretch to 2 to 3 weeks because the utility schedules its part separately. The utility-side work is usually free.
