Project overview in Charlotte, NC
On March 16, 2026, Touchstone Electric’s Charlotte team (Matthews branch) completed an indoor subpanel installation for homeowner Charla Williams in Charlotte, NC. Lead technician Danny Bishop furnished and installed a midsized garage subpanel, sized to support current household needs and make room for a permitted EV charger addition.
This project falls under our Panels & Service Upgrades category, with a focus on professional Subpanel Installation for safe capacity expansion and cleaner circuit organization.
What we installed
- Midsized indoor subpanel (12/24, up to 125A): A versatile, space-efficient panel mounted in the garage to accommodate present circuits and future loads.
- 100A 2‑pole feeder breaker: Installed to supply the new subpanel with reliable, dedicated capacity.
- Four 15A standard breakers: Configured for bathroom lighting and standard branch circuits in alignment with 2020 code requirements.
- 1/0 SER 4‑wire feeder (approximately 10 ft): Service‑entrance rated cable run from the main panel to the subpanel to deliver robust, code‑compliant power distribution.
- Permitting for an EV charger: The new panel was added to the electrical permit to facilitate a future car charger installation in the garage.
The result is a tidy, expandable panel layout that opens up circuit space, reduces strain on the main panel, and positions the home for a smooth EV charger upgrade.
Why a garage subpanel was the right move
- Room for growth: Extra breaker capacity for new circuits and an EV charging circuit without overloading the main panel.
- Convenience: Locating the subpanel in the garage simplifies future additions and maintenance for garage and nearby loads.
- Organization: Grouping related circuits in one panel improves labeling, troubleshooting, and long‑term serviceability.
Clean installation and homeowner expectations
To complete the installation, a small section of sheetrock below the new panel was cut. As noted at the time of service, Touchstone Electric is not responsible for any sheetrock repairs. Our team completed neat penetrations and kept the work area tidy so patching and painting can be handled efficiently after inspection.
Permitting and code notes
This installation was performed under an electrical permit in Charlotte, NC and includes the subpanel as part of the plan for a future EV charger. As local inspectors continue implementing NEC 2020 requirements, some homes may be asked to upgrade certain circuits to AFCI protection. In some cases, adding AFCI protection can reveal preexisting issues such as shared neutrals, which may cause nuisance tripping and require additional diagnostic time to resolve. Our team is prepared to identify and address these conditions when they arise.
