Durham 200A Panel Upgrade with Whole‑Home Surge Protection
Our Raleigh branch completed a comprehensive 200‑amp service upgrade for homeowner Chris Doherty in Durham, NC on March 19, 2026. Led by technician Brad Williams, the project replaced the main electrical panel with a copper‑bus model, added whole‑home surge protection, modernized breakers, and improved the grounding system to meet current code and safety standards.
What We Upgraded and Installed
- Permit and inspection: Pulled the required permit and coordinated inspection for a code‑compliant installation.
- 200A main panel replacement (copper bus): Removed the aging panel and installed a new outdoor 200‑amp panel with a copper bus. We grounded and bonded the panel, labeled all circuits, reconnected the service entrance conductors, and tied in existing branch circuits.
- Whole‑home surge protection: Installed a service‑entrance surge protective device with a $100,000 / 10‑year manufacturer warranty for covered equipment.
- Breaker updates for safety and reliability:
- Standard breakers: 1× 80A, 1× 50A, 1× 40A, 3× 30A (double‑pole), 8× 20A, 6× 15A
- GFCI breakers: 1× 20A (bath/laundry/garage/exterior), 1× 15A (kitchen/exterior/crawl/basement/lighting as applicable)
- Grounding system upgrade: Drove a new ground rod and installed a continuous grounding electrode conductor back to the main service panel for a low‑impedance, code‑compliant path to ground.
- Service conductors: Added XHHW 4/0 stranded conductors where needed for durable, wet‑location‑rated connections.
- Limited power during outage: Provided temporary generator support to keep essential loads running while utility power was disconnected.
Why Choose a Copper‑Bus 200A Panel?
Copper bus bars offer superior conductivity, heat tolerance, and long‑term reliability compared to aluminum. For this Durham home, the new panel includes a 50‑year transferable warranty on the copper panel, helping protect your investment while reducing maintenance concerns over time.
Protection from Spikes and Surges
Service‑entrance surges from lightning, utility events, or large appliances can damage sensitive electronics and shorten the lifespan of HVAC systems and household devices. The installed whole‑home surge protector diverts excess voltage safely to ground, providing a robust first line of defense for the entire home. This model carries a $100,000 equipment warranty for 10 years in the event of a covered surge‑related failure.
Code and Safety Considerations
As inspectors adopt newer NEC standards, certain circuits may require updated protective devices (for example, AFCI in designated areas). In some homes, preexisting conditions like shared neutrals can cause nuisance tripping and may require circuit diagnostics to resolve. For this project, we modernized breakers and added GFCI protection where appropriate to align with current safety practices and inspection requirements.
Warranties Included
- Signature Lifetime Craftsmanship Warranty: Our workmanship is backed for the long haul.
- Panel warranty: 50‑year transferable coverage on the copper‑bus panel.
- Surge protector warranty: $100,000 equipment coverage for 10 years. Claims are secondary to your insurance; direct lightning strikes are excluded. Security systems and medical equipment are not covered.
