600A CT Cabinet, Meter Base & 200A Panels — Mooresville, NC
Touchstone Electric completed a comprehensive 600-amp service upgrade for Matthew Johnson in Mooresville, NC. Led by technician Ben Lively from our Charlotte team (Matthews branch), this project modernized the property’s electrical infrastructure with utility-grade components, outdoor main breaker panels, robust grounding, and whole-home surge protection. Completed on September 25, 2024, the installation was permitted and inspected for code-compliant performance and safety.
Project scope and what we installed
- Installed and supplied a 600A CT cabinet for utility metering
- Installed and supplied a CT-rated meter base
- Installed and supplied three 200A outdoor main breaker panels
- Installed and supplied a complete grounding and bonding system
- Installed and supplied a whole-home surge protector
- Installed and supplied wire trays for clean, supported conductor routing
- Filed the electrical permit and coordinated all required inspections
Note: Touchstone will not be responsible for electrical work inside the building.
How this upgrade benefits the home
- Reliable capacity for today and tomorrow: The 600A service with three 200A mains supports high-demand loads, additions, detached structures, EV charging, and future projects.
- Improved safety: New outdoor-rated panels were grounded and bonded to current code, with clear labeling and organized terminations.
- Whole-home surge protection: Adds a vital layer of defense for sensitive electronics and appliances during voltage spikes.
- Clean, serviceable layout: Wire trays and neat conductor management simplify maintenance and future expansions.
- Code-compliant metering: CT cabinet and CT meter base deliver utility-ready accuracy and easier service coordination.
Materials and methods
Our team installed heavy-gauge THHN 4/0 conductors for high-capacity feeders and utilized outdoor-rated aluminum main panels brought to current electrical code. Each panel was grounded, bonded, labeled, and reconnected to existing service entrance conductors and branch circuits. To minimize disruption during the scheduled outage, we planned for a temporary generator solution to provide limited power if needed.
Inspection-ready and compliant
From permitting to final inspection, Touchstone Electric handled the process to help ensure a smooth utility handoff and a safe, compliant installation. Our Charlotte-area team follows NEC requirements and local Mooresville/region standards for service equipment, grounding electrodes, conductor sizing, and exterior panel installations.
Home Safety Plan included
This project included our Annual Home Safety Plan - GOLD initial inspection to benchmark the system after the upgrade. Key checks include:
- Panel inspection: voltage readings, bus condition, bonding, and proper KO sealing
- Safety device testing: surge protector and service disconnects
- Main service review: meter base condition, feeders, riser/weatherhead, water intrusion, and grounding system
- Home protection systems: Smoke/CO detectors, security and camera systems
- Equipment disconnects: HVAC and major appliances
- GFCI testing in required areas
