Electrical Panel Upgrades in Florence, SC — 100A & 200A Service, Replacements
100A and 200A panel upgrades, full replacements and fuse-to-breaker conversions, permitted and inspected.
Electrical Panel Repair & Upgrades in Florence & the Pee Dee
Your panel is the heart of the home's electrical system. If you're adding an EV charger, a heat pump, a hot tub, or just tired of nuisance trips and an old fuse box, an upgrade to a modern 100A or 200A breaker panel gives you safe, expandable capacity. Palmetto Electric handles the full job — load calculation, permit, new panel and breakers, grounding, and the utility coordination — and we leave it labeled and inspection-ready.
Florence has plenty of homes from the 1960s–80s with undersized 60A–100A services and obsolete equipment. We tell you honestly whether yours needs a repair, a replacement, or just a few breakers.
Common problems we fix
- Old fuse box or a 60A–100A service that trips under modern loads
- Federal Pacific (Stab-Lok) or Zinsco panel that won't reliably trip
- Adding an EV charger, hot tub, heat pump or addition
- Rust, moisture, scorching or a burning smell at the panel
- Double-tapped breakers and a full, no-space panel
- Aluminum service entrance or loose main lugs
- Home insurance or sale requiring a panel update
What homeowners ask us first
Do I need 100A or 200A service?
Most modern homes go to 200A, especially with electric heat, EV charging or a hot tub. A smaller home with gas appliances may be fine at 100A. We run a load calculation so you don't pay for more — or less — than you need.
Can you just replace the breakers instead of the whole panel?
Sometimes. If the panel bus and enclosure are sound and the brand is safe, replacing individual breakers is cheaper. If it's a Federal Pacific or Zinsco panel, replacement is the safe call — see our panel-safety guide.
What is a fuse-to-breaker conversion?
We replace an old screw-in fuse box with a modern breaker panel. Breakers are safer, resettable, and required for most upgrades and added circuits.

How long does a panel upgrade take?
Most residential service upgrades are completed in a day, including the utility disconnect and reconnect. We coordinate the permit and inspection.
Will my power be off during the upgrade?
Yes, for several hours while we swap the panel. We schedule it to minimize disruption and restore power the same day.
Do I need a permit for a panel upgrade in Florence?
Yes. Service and panel work requires a permit and inspection in South Carolina, and the utility won't reconnect without it. We handle the paperwork.
How much does a 200A panel upgrade cost?
It depends on the service entrance, meter base, grounding and any corrections needed. We give a firm quote after a load calculation. Call (843) 595-9236.
