When Does Your Home Need a 200-Amp Service Upgrade?

Modern Kentucky homes run more electrical load than builders planned for in the 1980s and 90s. Heat pumps, EV chargers, and standby generators all stress an aging 100-amp service — and Federal Pacific or Zinsco panels are a safety issue on their own.

See our service upgrade options — licensed electricians serving Lexington and Central Kentucky.

Signs you need more capacity

If you're adding major loads, your panel may already be at its limit. These are the most common triggers we see in Fayette County homes:

Frequent breaker trips when AC and dryer run together
Adding an EV charger, heat pump, or standby generator
100-amp service with no room for new circuits
Federal Pacific or Zinsco panel — insurance and safety concern

Cost and timeline

Most straightforward 200A service upgrades in Central Kentucky fall between $2,400 and $3,800 including permits and utility coordination. Power is out for a few hours during the cutover — we schedule around your needs.

Pairs with other upgrades

Many Lexington homeowners bundle a 200A upgrade with EV charger installation or a generator transfer switch. One coordinated project avoids duplicate permit and labor costs. Book a consultation to plan your upgrade.
