Code-Compliant Federal Pacific Subpanel Replacement in Columbia, SC

Touchstone Electric’s Columbia team completed a safety-focused Panels & Service Upgrades project with a specialized Subpanel Installation for homeowner Chris Cooper. On July 10, 2024, our technician Tyler Harris replaced a recalled 100-amp Federal Pacific subpanel, installed a code-required furnace disconnect, and corrected improper wiring with the proper #10 AWG conductors rated for 30 amps. The result is a cleaner, safer, and fully code-compliant electrical distribution setup for this Columbia, SC home.

Following the work, Chris Cooper praised our service with a positive review, recognizing our attention to detail and commitment to electrical safety.

What We Replaced and Installed

Federal Pacific equipment has a documented history of reliability concerns, and in this home the existing subpanel and disconnect were due for replacement. We removed the recalled subpanel and installed a modern, midsized indoor subpanel designed for dependable performance and easier maintenance. We also corrected the existing 30-amp disconnect that was fed from the old panel, ensuring it was rewired with properly sized conductors and protected by the correct breaker.

  • Removed: Recalled 100-amp Federal Pacific subpanel and outdated Federal Pacific disconnect with improper wiring.
  • Installed: A midsized indoor subpanel (12/24, up to 125 amps) to serve existing household circuits.
  • Added disconnect: ≤60-amp pull-out equipment disconnect to provide a safe, visible means of isolation for servicing equipment.
  • Corrected wiring: Rewired affected 30-amp circuits with #10 AWG NM-B (10/2) conductors appropriate for 30-amp loads.
  • Code-compliant furnace disconnect: Provided per NEC 440.11, which requires a disconnect for any furnace connection.
  • Labeling and testing: All new breakers and circuits were labeled and function-tested for proper operation.

Breakers and Circuit Updates

To pair the new subpanel with the home’s existing loads, we installed new breakers that match each circuit’s ampacity and application. This ensures correct overcurrent protection and helps prevent nuisance tripping and overheating.

  • Two 30-amp double-pole breakers for 30A equipment and appliances.
  • One 50-amp standard breaker for higher-demand loads such as ranges or subfeeds.
  • Two 15-amp tandem breakers to serve lighting and general-use circuits where appropriate.
  • One 20-amp tandem breaker for small appliance circuits.
  • Two 20-amp standard breakers for dedicated small appliance loads.
  • Four runs of #10/2 NM-B to support the corrected 30-amp circuits.

Why This Work Matters

Recalled and outdated electrical gear can compromise safety and reliability. By replacing the Federal Pacific subpanel, upgrading the disconnect, and matching each circuit with the correct breaker size and conductor, we reduced potential hazards and improved system performance. The dedicated furnace disconnect—required by NEC 440.11—adds a clear, on-site means to de-energize equipment during service, protecting both the home and anyone performing maintenance.

Benefits for the Homeowner

  • Safety: Modern, code-compliant subpanel and properly sized conductors reduce overheating and tripping risks.
  • Serviceability: Clearly labeled circuits, a visible disconnect, and appropriate breakers streamline maintenance and future upgrades.
  • Reliability: New breakers and corrected wiring support stable operation of everyday appliances and HVAC equipment.
  • Prepared for the future: A midsized subpanel offers room to adapt as household electrical needs evolve.
