It is not advisable. Many Challenger panels from that period have known safety issues, including faulty bus bars and breakers that may not trip properly under fault conditions. A 150A service from 1998 likely lacks the spare capacity for a 40-50 amp EV charger circuit without a full load calculation. The safest path is a panel upgrade to a modern, UL-listed unit with AFCI/GFCI protection, which provides the necessary capacity and safety for major new loads.

For summer peaks, ensure your HVAC system is serviced and consider a hard-wired surge protector to guard against grid-switching surges. For winter storm preparedness, a properly installed generator with a transfer switch is critical. Never use a portable generator with extension cords plugged into household outlets—this is a major fire hazard and can backfeed the grid, endangering utility workers. A transfer switch isolates your home and allows safe operation of essential circuits.

First, turn off the main breaker to the 150A panel immediately. Our typical response from Cane Savannah Elementary School, using US-76, is about 12-15 minutes. A burning smell often indicates a failing connection on a bus bar or a breaker that has overheated to the point of failure. Do not attempt to reset any breakers. Securing the main power prevents further damage and reduces fire risk until the issue can be diagnosed.

All panel work requires a permit from the Sumter County Planning and Zoning Department and a final inspection. As a Master Electrician licensed by the South Carolina Department of Labor, Licensing and Regulation, I handle that process. The work must comply with the 2023 National Electrical Code, which mandates AFCI protection for most living area circuits and specific surge protection requirements for dwelling units. This ensures the installation is documented, safe, and up to modern standards.

Overhead service masts are common here. You should visually inspect the mast head and weatherhead for rust, damage, or where the service drop cable enters your home. Ensure tree branches are trimmed well back from the lines. The mast is your responsibility from the weatherhead down. Any sagging, corrosion, or physical damage compromises the seal against moisture and can lead to service interruptions or a fire hazard at the point of entry.

Your electrical system is now 28 years old. Homes in the Sumter County Fringe built around that time were wired with standard NM-B Romex for the expected loads of the era. Modern kitchens, home offices, and entertainment systems draw significantly more power than a 1998 panel was designed to handle. This mismatch often causes voltage drops, seen as dimming lights, and can lead to overheating on circuits that are now overloaded.

While utility fluctuations can contribute, our location on the flat coastal plain sees frequent lightning, which is a primary cause of damaging surges. Duke Energy Progress manages the grid, but surges can travel miles from a strike. Modern solid-state electronics are highly sensitive. A whole-house surge protective device installed at your service entrance is the only effective defense, working in tandem with point-of-use protectors to clamp these high-voltage transients.

Yes, terrain directly impacts grounding effectiveness. Sandy, low-moisture soil on the coastal plain has higher electrical resistance, which can impair the function of your grounding electrode system. This is critical for surge protection and safety. We often need to install additional ground rods or use chemical treatments to achieve the low-resistance ground required by code, ensuring fault current has a reliable path to earth.
