100-Amp to 200-Amp (or Higher) Electrical Panel Upgrades
When you add an EV charger, central air, a home addition, or simply need more modern electrical capacity, a 100-amp to 200-amp service upgrade (or higher) ensures safety, code compliance, and uninterrupted power for all your appliances.
Why Upgrade Your Electrical Service?
-
Meet Increased Power Demands
Modern homes often exceed the limits of a 100 amp service. Upgrading to 200 amps (or 300/400 amps) prevents frequent breaker trips and voltage drop. -
Enhance Home Safety
A new, UL-listed breaker panel and properly sized conductors reduce fire risks and protect your wiring from overheating. -
Protect Your Insurance & Resale Value
Insurance carriers and future buyers expect up-to-code electrical service. A documented upgrade boosts home value and avoids claim denials.
