Your Locally Owned Electrician in Greenville, SC | Expert Repairs, Installations & Upgrades

You should call an emergency electrician at Mr. Electric of Greenville-SC immediately if you notice:

• A burning smell near outlets or your electrical panel
• Sparking or smoking from any electrical component
• Outlets or switches that feel warm to the touch
• Repeated circuit breaker trips that happen even after resetting

These warning signs point to dangerous conditions such as overloaded circuits, loose connections that generate heat, or failing electrical components. Greenville's humid climate accelerates wear on electrical connections, and with 45 to 70 thunderstorm days annually in South Carolina, so storm damage to electrical systems is common. If you experience any of these electrical emergencies after a severe storm, turn off the power at the main breaker and call us right away. Electrical fires start small but spread fast.

Most homes built before the 1990s in Greenville need electrical panel upgrades to handle modern electrical demands. Older homes typically have 60- to 100-amp service, which was adequate decades ago when families didn't have multiple computers or TVs, but falls short today. Between central air conditioning, home offices with multiple devices, kitchen appliances, EV charging stations, and smart home services, the average home now requires 200-amp service.

Greenville County is the largest county in South Carolina by population, and many neighborhoods feature homes from the 1960s, 70s, and 80s with original electrical panels. If your breakers trip frequently, lights dim when appliances turn on, or you are adding major electrical loads like an electric vehicle charger, an electrical panel upgrade is the safest solution. Our licensed electrical contractors perform load calculations to determine your actual electrical needs and handle the permit process through Greenville County's eTrakit system.

If you experience frequent circuit breaker trips, flickering or dimming lights when appliances turn on, or there's a burning smell near the panel, it's time for an upgrade. Additionally, if your electrical panel is over 25 years old, has rust or corrosion on the breaker box, or you need to add new high-demand circuits, you should call our electricians to discuss upgrading it.

If your home has a Federal Pacific Electric or Zinsco panel, replacement is strongly recommended regardless of its age. These panels are commonly found in homes built between the 1950s and 1980s in Greenville, and have documented failure rates and are considered fire hazards by electrical safety experts. Many insurance companies will refuse coverage or charge higher premiums for homes with these panels installed. All electrical panel upgrades in Greenville County require permits and inspections to ensure your new system meets the current electrical code. Our electricians will inspect your panel, explain what we find, and provide upfront pricing for replacement.

Knob-and-tube wiring, common in Greenville homes built before 1950, is not inherently unsafe if completely original and unmodified. The problem is that most knob-and-tube systems have been altered over the decades with splices, added circuits, and deteriorating insulation. The electrical wiring has no ground wire, cannot safely support three-prong outlets, and was never designed for modern electrical loads.

Most insurance companies refuse to cover homes with active knob-and-tube wiring due to fire risk. If your home still has this wiring, a full rewire is the safest long-term solution. Our Greenville electricians inspect the wiring, explain the risks specific to your home, and provide options for rewiring room by room or all at once. Rewiring requires permits through Greenville County Building Safety and typically takes several days, depending on the size of your home.

Whole-home surge protection is highly recommended for Greenville homes. South Carolina experiences 45 to 70 thunderstorm days annually, and the state averages 14.6 lightning strikes per square mile each year, according to the South Carolina State Climatology Office. A single lightning strike near your home or a surge from the utility grid can destroy electronics, appliances, and damage your electrical panel.

Whole-home surge protector devices are installed at your main electrical panel and protect every circuit in your home from external surges caused by lightning or utility issues. It does not replace surge protector power strips for sensitive electronics, but it provides the first line of defense. Installation typically takes a few hours, and the device adds significant protection for a relatively small investment compared to replacing damaged appliances and electronics after a surge.

Greenville, SC has a subtropical climate with hot, humid summers and frequent thunderstorms, which places extra demand on your electrical system. High humidity accelerates corrosion of electrical connections and components. Hot temperatures mean air conditioning systems run for extended periods during the summer months, increasing the electrical load. With 45 to 70 thunderstorm days each year across South Carolina, power surges from lightning strikes are a constant risk. Humidity also affects outdoor electrical components, GFCI outlets, and any electrical wiring in crawl spaces or unfinished areas. We recommend seasonal electrical inspections before summer to ensure your system can handle peak cooling demand, and whole-house surge protection to guard against the frequent thunderstorms that roll through Greenville County.

Electrical permits are required in Greenville County for all new installations, alterations, electrical repairs, and replacements. This is to ensure work complies with the 2020 National Electrical Code adopted by South Carolina. According to Greenville County Building Safety, all permits are processed through the eTrakit system with a typical review period of 2 to 3 weeks. Electrical inspections are required on all permitted electrical work to verify safety and code compliance. Unpermitted electrical work puts you at risk for fines, failed home inspections during a sale, insurance claim denials, and, most importantly, safety hazards. Our licensed electrical contractors handle the permit application process and schedule required inspections as part of every job. Electrical work requiring permits includes:

• Electrical panel upgrades
• Circuit additions
• EV charging station installations
• Generator installations
• Wiring repairs
• Most outlet or switch work beyond simple fixture replacement

The permit review process in Greenville County currently takes 2 to 3 weeks through the eTrakit system, according to Greenville County Building Safety. This is the review and approval time before electrical work begins. Once the permit is issued, we schedule the work, complete the installation, and then schedule the required final inspection. For a straightforward electrical service, such as adding a dedicated circuit or EV charger, the total timeline from permit application to completed inspection is typically 3 to 4 weeks. Larger projects, such as electrical panel upgrades, will take about 4 to 6 weeks to complete. To ensure your installation goes smoothly, plan ahead, especially if you have a specific deadline. We submit permit applications as soon as you approve the work and keep you updated on approval status and inspection scheduling throughout the process.

The 2020 National Electrical Code was adopted in South Carolina with an effective date of January 1, 2023. It requires GFCI protection in bathrooms, kitchens (countertop receptacles), garages, outdoors, crawl spaces, laundry areas, wet bar sinks, and within 6 feet of any sink, tub, or shower. GFCI outlets detect imbalances in electrical current and shut off power in milliseconds to prevent electrocution.

Many older Greenville homes built before these requirements were in effect lack GFCI protection in these areas. Retrofitting GFCI outlets is often required during home sales, remodeling projects, or when adding circuits in these locations. Our electrical contractors install GFCI outlets that meet current code, test them to ensure proper function, and label circuits clearly. Upgrading to GFCI protection is one of the most important electrical safety improvements you can make for home safety.

A comprehensive electrical safety inspection examines your electrical panel for proper amperage and circuit labeling. It looks for signs of overheating or corrosion, and whether breakers match circuit wire sizes. We inspect visible electrical wiring for damage, improper splices, outdated materials like knob-and-tube or aluminum wiring, or ungrounded wires. Outlets and switches are tested for proper grounding, GFCI function in required locations, and secure connections.

We check for code violations, evaluate whether your electrical system meets current demand, and identify safety hazards like overloaded circuits or Federal Pacific panels. The electrical inspection typically takes 1 to 2 hours, depending on the home's size. We provide a written inspection report explaining what we found, what needs immediate attention, and what upgrades improve safety or prepare your home for added electrical load. Electrical inspections are recommended every 3 to 5 years, before buying or selling a home, or when adding major appliances or EV charging stations.

Our Greenville electricians recommend scheduling a professional electrical safety inspection every 3 to 5 years. This helps to catch problems before they become dangerous or expensive. But schedule one immediately if you notice flickering lights, frequent breaker trips, warm outlets, burning smells, or any other unusual electrical symptoms. Greenville County mandates electrical inspections for all permitted electrical work. Inspections are strongly recommended before buying or selling a home, after storm damage, when planning major remodeling projects, or before adding high-demand electrical loads, such as EV charging stations or home additions. Homes over 25 years old benefit from inspections even without obvious problems, as wiring insulation deteriorates over time and connections loosen. Regular electrical inspections identify issues early, keep your electrical system code-compliant, and protect your family from electrical fires and shock hazards.

South Carolina law allows homeowners to perform minor electrical work on their own primary residence, such as replacing a light fixture or swapping out a switch. But most electrical work requires a permit and a licensed electrical contractor. According to Greenville County Building Safety, residential rental properties must use a South Carolina-licensed contractor for all electrical work. Even in your own home, electrical work involving electrical panels, circuits, electrical wiring, or anything requiring a permit must be done by a licensed electrician.

The risks of DIY electrical work include electrocution, fire, code violations, failed inspections, fines, and insurance claim denials if the work is improper and causes damage. Our licensed electrical contractors hold valid South Carolina electrical contractor licenses issued by SCLLR, carry insurance, and guarantee all electrical work meets code. We handle permits and electrical inspections, ensuring the job is done safely and correctly the first time.

Every electrician on our team holds a valid South Carolina electrical contractor license issued by the state's Department of Labor, Licensing, and Regulations (SCLLR). South Carolina law requires all electricians to carry this license when performing electrical work in Greenville and the surrounding areas. Before obtaining a license, electrical contractors must pass exams demonstrating competency with the National Electrical Code and local ordinances, and provide verified work experience.

Our team maintains licensing through ongoing education on code updates and safety standards. You can verify our licensing status at any time through the SCLLR Licensee Lookup system. Licensed electrical contractors carry insurance, understand the current electrical code, and guarantee that electrical work meets safety standards. Hiring unlicensed electricians puts you at risk for unsafe work, code violations, and no recourse if problems arise.

A backup generator makes sense for Greenville homeowners who want protection from power outages caused by the 45 to 70 thunderstorms South Carolina experiences annually. Whole-home generators automatically detect power loss and restore electricity within seconds. This ensures your HVAC, refrigerator, medical equipment, and essential systems keep running during a power outage. Portable generators will cost less upfront but require manual setup, fuel storage, and only power select circuits. Your decision depends on how often your area loses power, whether anyone in your home relies on medical equipment, and your budget.

Generator installation requires an electrical permit through Greenville County, a dedicated circuit, and proper placement outside your home. The licensed electricians at Mr. Electric of Greenville-SC will size the generator based on your electrical load, handle the permit and inspection process, and ensure safe installation. Natural gas generators connect to your existing gas line, while propane models require a tank. Contact us today for a generator installation or to learn more about our local electrical services.
