If your panel is outdated, undersized, or showing warning signs, it's not just an inconvenience — it's a safety risk.
Swamp Rabbit Electric provides professional electrical panel upgrades for homeowners and businesses throughout Greenville, SC and the Upstate. With over two decades of hands-on electrical experience, we handle panel upgrades the right way — safely, up to code, and at a fair price.

Most homeowners don't think about their electrical panel until something goes wrong. Here are the warning signs that your panel is falling behind:
If you're resetting breakers every week, your panel can't keep up with your home's electrical demand.
Happens often when you turn on heavy appliances like the dryer, microwave, or AC unit.
Panels from the 1980s and 1990s weren't built for today's heavy electrical loads.
Fuse boxes lack the modern safety features and total capacity of modern circuit breaker panels.
An EV charger, heat pump, hot tub, or home addition all require more amperage than older panels can deliver safely.
This is an emergency — shut off your main breaker and call us immediately.
These brands have known safety defects linked to house fires. Replacement should be a priority.
An electrical panel upgrade is more than swapping out a box on the wall. Here's what the process looks like when Swamp Rabbit Electric handles the job:
We start by evaluating your current panel, wiring, and electrical load. This tells us exactly what amperage your home needs and whether any additional work is required.
Most Greenville homes upgrading from a 100-amp panel will move to a 200-amp panel, which is the current standard for modern residential construction. We'll recommend the right panel size based on your home's actual needs — not a one-size-fits-all upsell.
Electrical panel work requires a permit in Greenville County. We handle the permit application and coordinate the required inspection so your upgrade meets all current NEC and local code requirements, including whole-house surge protection and arc-fault circuit interrupter (AFCI) breakers where required.
Our licensed electricians remove the old panel, install the new one, transfer and label all circuits, and verify every connection. We also check your grounding system and meter base to make sure the entire service is up to standard.
After installation, a county electrical inspector verifies the work. You get a safe, code-compliant panel and the documentation to prove it.
The most common panel upgrade we perform in Greenville is moving from a 100-amp panel to a 200-amp panel. This is the upgrade most homeowners need when they're experiencing tripped breakers, adding new appliances, or planning a renovation.
A 200-amp panel gives you room to safely power today's electrical demands — central HVAC, electric water heaters, EV chargers, home offices, and smart home systems — without overloading your circuits.
If your home was built before 2000 and still has its original panel, there's a good chance you're running on 100 amps or less. Many older homes in Greenville neighborhoods like North Main, Augusta Road, Overbrook, and the West End were wired for a fraction of the electrical load that modern families use daily.
The cost of an electrical panel upgrade depends on several factors, including your current panel size, the new panel's amperage, the condition of your existing wiring, and whether your meter base or service entrance needs to be upgraded at the same time.
For a standard 100-to-200-amp panel upgrade, most Greenville homeowners can expect to invest between $1,800 and $4,000, depending on the scope of work. A simple like-for-like panel replacement where the amperage stays the same will typically fall on the lower end.
Factors that can affect your price include the age of your home, accessibility of the panel location, whether new wiring is needed, and permitting fees. Homes with outdated wiring, panels in difficult-to-access locations, or service entrance equipment that also needs replacement will be on the higher end.
Look at the main breaker at the top of your panel — the number printed on it is your panel's amp rating. Or just give us a call and we'll tell you.

Whether you're searching for an electrician near you, emergency electrical repair, panel upgrades, EV charger installation, or lighting services in Greenville—you're in the right place.
Most panel upgrades are completed in a single day, typically within four to eight hours. Larger projects or homes requiring additional wiring work may take longer, but we'll let you know the timeline upfront.
Yes. Electrical panel upgrades require a permit in Greenville County, and the work must pass a code inspection. We handle the entire permitting process for you.
If your home was built before 2000, has a 100-amp panel, and you're adding large appliances like EV chargers, heat pumps, or additional HVAC units, a 200-amp upgrade is almost always the right call. We can perform a load calculation to confirm.
Absolutely. Beyond preventing electrical fires and eliminating nuisance breaker trips, a modern panel increases your home's resale value, allows you to run today's appliances safely, and brings your electrical system into compliance with current safety codes.
A panel replacement swaps your old panel for a new one at the same amperage. A panel upgrade increases your amperage — typically from 100 to 200 amps — which may also require upgrading your meter base, service entrance conductors, and grounding system.
Yes. These panels have well-documented safety issues, and we strongly recommend replacing them. If you're unsure what brand your panel is, we can identify it during an inspection.
