100A Subpanel Installation and Fuse Box Upgrade in Campobello, SC
Our Asheville team, serving the area from our Taylors branch, completed a professional panel upgrade and subpanel installation for homeowner Kim Chafee in Campobello, SC. Led by technician Aaron Smith, this project modernized an aging fuse box, added a new 100-amp feeder to a midsized indoor subpanel, and included thorough diagnostics to ensure safe, reliable power throughout the home. Completion date: August 18, 2025.
Project overview
Older fuse boxes can limit capacity and make maintenance difficult. By replacing the fuse box with a modern breaker panel and adding a properly fed 100A subpanel, we created more circuit space, improved safety, and positioned the home for future electrical needs like appliances and renovations.

- Secondary category: Subpanel Installation
- Location served: Campobello, SC
- Technician: Aaron Smith
Scope of work completed
- Fuse box replacement: Removed the existing fuse box and installed a compact breaker panel for safer, easier reset and maintenance.
- Midsized indoor subpanel (12/24 up to 125A): Added a dedicated subpanel to create room for new and existing circuits.
- 100A feeder installation: Installed a 4-wire SER #2 service-entrance cable (approximately 40 feet) from the main panel to the new subpanel to provide a full 100-amp capacity.
- Main breaker for subpanel: Installed a 100-amp two-pole breaker to safely supply the subpanel.
- Branch breaker updates: Added two 15-amp standard breakers to support lighting and standard circuits as needed.
- Water heater connection: Connected a new water heater once it was on site and the home was ready for final hookup.
- Circuit reconnection and cleanup: Reconnected circuits to the new panel correctly and corrected improper connections identified during testing.
- Electrical permit: Filed the electrical permit with the county and coordinated inspections.
- Scheduling note: The initial visit found the job not ready; we returned promptly to complete installation once conditions were met.
This combination of panel replacement, subpanel installation, and breaker updates restored capacity and improved safety while providing space for future expansion.
Code compliance and diagnostics
We followed current NEC practices, including running a 4-wire feeder so the subpanel has isolated neutrals and grounds. During diagnostics, we inspected, tested, and corrected any circuits that were connected improperly to reduce nuisance tripping and improve reliability.
As local inspectors increasingly implement NEC 2020, some projects may require AFCI protection on certain circuits. Preexisting conditions like shared neutrals can cause immediate tripping when AFCI protection is added. If those issues are discovered, additional diagnostics and circuit corrections may be recommended to bring the system into compliance.
