Project overview: 400 Amp Service Upgrade & Panel Installation in Charlotte

Touchstone Electric’s Charlotte team from our Matthews branch completed a comprehensive 400 amp service upgrade for Boon & Company Construction in Charlotte, NC. Led by technician Danny Bishop, this project was completed on April 9, 2024 and designed to provide abundant capacity, robust surge protection, and a clean, serviceable layout for future electrical needs.

This job falls under our core specialties: Panels & Service Upgrades and Meter Base & Service Replacement, ensuring the home’s electrical infrastructure is safe, expandable, and utility-compliant.

Scope of work on this Charlotte service upgrade

We furnished and installed a new 400A service with carefully planned distribution and protection. The installation included:

400 amp CT meter can for accurate metering and utility interface.
200 amp garage disconnect to provide local isolation and serviceability for the garage panel.
200 amp, 30‑circuit exterior main breaker panel for organized, code-friendly circuit management with room to grow.
Two whole‑house surge protectors to safeguard sensitive electronics and major appliances from transient voltage spikes.

The builder coordinated with the utility’s engineering team to align metering and service requirements for a smooth cutover.

Why upgrade to a 400A service?

Modern homes and residential projects in Charlotte increasingly demand higher capacity due to larger HVAC systems, electric vehicle charging, workshop equipment, and future-ready additions. A 400A service helps by:

Supporting multiple high‑demand loads simultaneously without nuisance tripping.
Providing headroom for future circuits such as EV chargers, hot tubs, or expansions.
Improving overall reliability and safety of the electrical distribution.
Organizing circuits in a clear, maintainable layout for easier service and inspections.

Installation standards and workmanship

Our team follows current code and local utility requirements, focusing on neat workmanship and long‑term reliability. Typical best practices on projects like this include:

Proper conductor sizing, terminations, and torque verification.
Appropriate grounding and bonding for service equipment.
Weather‑resistant, exterior‑rated equipment and clear working space.
Accurate labeling for disconnects, panels, and surge devices.

The result is a safe, scalable service that’s ready for today’s loads and tomorrow’s upgrades.
