EV Charger & High-Power Equipment Panel Upgrades
Common Upgrades That Require Panel Replacement
Most modern electrical upgrades require more power than older panels can safely provide. Homes built before 2000 often have 100-amp service, which may be insufficient for EV charging, electric appliances, and high-efficiency HVAC systems.
We perform NEC-compliant load calculations to determine whether your existing panel can support new equipment or if a service upgrade to 200 amps is recommended.

Initial Consultation & Estimate
Professional Installation & Configuration
Testing & Ongoing Support
We evaluate your existing electrical panel, service size, and wiring to determine whether a replacement or upgrade is required. Our electricians perform NEC-compliant load calculations to assess your home’s power needs for EV chargers, appliances, HVAC systems, and future expansion.
Our licensed electricians remove the existing panel and install a new code-compliant breaker panel — typically upgrading to 200-amp service for modern homes.
This includes grounding and bonding corrections, circuit organization, labeling, and replacement of outdated components. All work is performed according to the National Electrical Code and local municipal requirements.
Once installation is complete, we test all circuits, verify proper operation, and coordinate inspection approval if required. Power is restored after final connections and utility authorization.
