Overview

Cellino Plumbing, Heating, Cooling & Electric completed a 100-amp sub panel installation and Level 2 EV charger setup for homeowner Luke Salaam in Williamsville, NY. As electric vehicle ownership became more common, the homeowner wanted a dedicated charging solution that delivered faster charging speeds without overloading the existing electrical system.

 

After evaluating the home’s current electrical capacity, our team recommended installing a 100-amp sub panel to safely support additional demand. This upgrade allowed for the installation of a 48-amp Level 2 EV charger, providing significantly faster and more reliable charging compared to standard outlets.

 

The result was a future-ready electrical system designed to support both current EV needs and potential future upgrades.

Challenge: Adding EV Charging Capacity Safely

Installing a high-capacity EV charger requires careful load calculations, proper circuit protection, and strict adherence to electrical codes. The existing panel did not have sufficient capacity to safely support a 48-amp charger alongside the home’s everyday electrical usage.

 

Our electricians needed to integrate the new sub panel seamlessly while maintaining proper grounding, breaker sizing, and clear labeling. Routing wiring efficiently and positioning the charger for convenient daily use were also key considerations.

 

Cellino’s team coordinated every step to ensure the system upgrade was completed safely, efficiently, and with minimal disruption to the homeowner.

The completed project delivered fast, dependable EV charging without compromising household electrical safety. The new 100-amp sub panel provides dedicated capacity for the charger while preserving the integrity of the home’s primary electrical system.

 

The 48-amp Level 2 EV charger now allows Luke to charge his vehicle quickly and reliably at home, eliminating reliance on public charging stations. Clean installation, proper labeling, and thorough testing ensured the system was fully operational and built for long-term performance.

 

The homeowner appreciated the clear communication, professional workmanship, and confidence that the electrical system is equipped to handle modern energy demands.
