It could be either, but given Greenville's high lightning strike frequency, grid-induced surges and sags are common. These voltage fluctuations are particularly hard on sensitive smart home electronics. The first step is to have us install whole-house surge protection at your main panel to defend against external spikes. We can then monitor your incoming power quality and inspect your home's internal connections to rule out loose wiring, which is another frequent cause of flickering in older systems.

Preparation focuses on protection and backup. For winter ice storms that can bring down lines, a properly installed and permitted generator with a transfer switch is key. For summer brownouts from peak AC demand, whole-house surge protection is critical, as brownouts and the subsequent power restoration often come with damaging voltage surges. Ensuring your heating and cooling equipment is on dedicated, properly sized circuits also helps it operate more reliably during these stressful grid events.

Yes, terrain directly impacts grounding efficacy. Rocky, shallow soil—common in our rolling foothills—has higher resistance, making it harder to establish a low-resistance path to earth for fault currents. This can compromise your grounding electrode system. We often need to drive additional ground rods or use concrete-encased electrodes (Ufer grounds) to achieve the NEC-required grounding resistance, ensuring your breakers will trip properly during a fault and protecting your home from lightning-induced surges.

Overhead service masts are standard, but they face specific challenges. The mast head and weatherhead can degrade over 40+ years, allowing moisture ingress that causes corrosion inside your panel. Heavy tree canopy in neighborhoods like the West End can cause line abrasion or fall on service drops during storms. We inspect the mast's structural integrity, the condition of the service entrance cables, and the seal at the weatherhead to prevent water damage, which is a leading cause of panel corrosion and failure.

For an emergency like that, our dispatch prioritizes immediate response. From our staging near Falls Park on the Reedy, we can typically be en route via I-385 and reach most West End addresses within 8 to 12 minutes. A burning odor indicates an active fault that requires immediate professional shutdown and diagnosis to prevent fire. Please evacuate the area around the panel and call for service right away.

Safely, no. A Federal Pacific panel is a known hazard with a high failure rate for breakers not tripping during a fault, and it must be replaced before any major upgrade. Furthermore, a 100-amp service from 1984 lacks the reserve capacity for a 40-50 amp EV charger or a heat pump's startup surge. This project starts with replacing the hazardous panel and almost certainly requires a service upgrade to 200 amps to provide safe, code-compliant power for modern demands.

Homes from that era, like many in the West End, were built for a different standard of electrical use. Your original 1984 NM-B Romex wiring and 100-amp service panel are now 42 years old and were designed for fewer, less power-hungry appliances. Modern kitchens and home offices add significant simultaneous loads that can strain an older system, causing voltage drop and that noticeable dimming. This is a clear sign your system is operating at its original design capacity, not a failure, but an indication an assessment is prudent.

All major work requires a permit from Greenville County Codes Enforcement and must comply with the 2023 National Electrical Code, which South Carolina has adopted. This includes a detailed plan for the new service, panel location, and load calculations. As a licensed Master Electrician through the SC Department of Labor, Licensing and Regulation, I handle the entire permit process—application, inspections, and final approval—ensuring the work is documented and safe, which is also required by Duke Energy before they will reconnect upgraded service.
