For summer peak loads, ensure your HVAC system is on a dedicated, properly sized circuit and consider an energy audit to balance loads. Brownouts strain motors and electronics. For winter ice storms, a permanently installed generator with an automatic transfer switch is the most reliable backup. This system isolates your home from the grid during an outage and provides safe, code-compliant power to essential circuits, preventing damage from frequent power cycling.

Frequent lightning in our area creates high surge risk on the Duke Energy Progress grid, but your home's internal protection is equally important. Utility-side surges can enter through your service entrance. While the utility manages the main grid, protecting your electronics requires a whole-house surge protector installed at your main panel. This device, required by the NEC for new services, clamps dangerous voltage spikes before they reach your sensitive smart home devices.

Overhead mast service is standard here, but it exposes the entrance cable to weather and physical damage. Common issues include masthead separation, water infiltration into the service panel, and damage from falling branches. The mast must be properly secured and sealed. During a service upgrade or inspection, we also verify the mast and cable are sized correctly for your new service capacity and that the point of attachment to your house is structurally sound.

A 100-amp panel from 1974 is likely insufficient for adding a heat pump and Level 2 EV charger simultaneously; doing so would overload the system. This is especially critical if you have a Federal Pacific panel, which is a known fire hazard due to breakers that can fail to trip. A full service upgrade to 200 amps is the standard, safe path forward, which also requires replacing any Federal Pacific equipment with modern, UL-listed panels and AFCI breakers per current code.

Yes, a permit from the Florence County Building Codes Department is legally required for a panel upgrade or service change. This ensures the work is inspected for safety and complies with the NEC 2023, which South Carolina has adopted. As a Master Electrician licensed by the SC Department of Labor, Licensing and Regulation, I handle the permit paperwork and scheduling, ensuring the installation meets all current standards for AFCI protection, grounding, and load calculations.

Yes, the sandy, low-resistance soil common on the coastal plain actually provides favorable conditions for a proper grounding electrode system. However, it's essential that your grounding rods are driven to the full depth required by code and that connections are tight and corrosion-free. A poor ground, even in good soil, can lead to stray voltage, ineffective surge protection, and compromised safety for the entire electrical system.

Your electrical system is over 50 years old, which is a key factor. Homes from that era in Downtown Johnsonville were wired with NM-B Romex, designed for far fewer and less powerful devices than we use today. Modern kitchens and home offices demand more power, and the original circuits are often overloaded, causing voltage drops you notice as dimming lights. Upgrading circuits or the main service panel is a common, code-compliant solution for 2026 living standards.

For an emergency like a burning smell, which indicates an active electrical fault, we prioritize immediate dispatch. From Johnsonville City Hall, we use US-41 for direct access, with a typical arrival time of 3 to 5 minutes. The first step is to safely disconnect power at the main breaker if possible, then we'll locate and isolate the fault—often a failing connection at an outlet or within the panel—to prevent a fire.
