Signs You Need an Electrical Panel Upgrade in Myrtle Beach, SC
Your electrical panel is the central hub of your home’s entire electrical system. Every circuit in your house — every outlet, light, appliance, and HVAC component — runs through it. When the panel is working properly, it quietly manages all of that load without you ever thinking about it. When it is not, the signs show up throughout your home, and ignoring them creates real safety risks.
For homeowners in Myrtle Beach, electrical panel issues are more common than in many other markets. The combination of older housing stock, the growing electrical demands of modern households, the stress of coastal storm seasons, and the humidity-driven wear that affects electrical components over time creates conditions where panel problems surface regularly. Knowing what to look for — and understanding when an upgrade is genuinely necessary — can protect your home, your family, and your investment.
At Greg Beverly Services, Inc., we have been handling electrical panel upgrades for Myrtle Beach homeowners for over 40 years. This guide covers the most common signs that your panel needs attention, what a panel upgrade actually involves, and what you should expect from the process.
What Does an Electrical Panel Do?
Before getting into the warning signs, it helps to understand what your panel is responsible for. The electrical panel — sometimes called a breaker box or load center — receives power from the utility company and distributes it through individual circuits to every part of your home. Each circuit has a dedicated breaker that is designed to trip (shut off) when the circuit is overloaded, preventing wires from overheating and potentially causing a fire.
An older home with a 100-amp panel was built for an era when households used a fraction of the electricity that today’s homes consume. A modern household with central air conditioning, electric appliances, home theater equipment, multiple computers, EV chargers, and smart home devices can easily exceed what a 100-amp panel was designed to handle. Most electricians and code authorities now recommend 200-amp service as the standard for new residential construction and major renovations.
Warning Signs That Your Myrtle Beach Home May Need a Panel Upgrade
1. Breakers That Trip Frequently
A breaker that trips occasionally is doing exactly what it was designed to do — protecting a circuit from overload. But breakers that trip frequently, on circuits that are not obviously overloaded, or that trip as soon as you reset them are telling you something important: the panel is struggling with the demands being placed on it.
If you find yourself resetting the same breaker more than a couple of times a year on an ordinary circuit, it is worth having the panel evaluated. Frequent tripping can indicate a circuit that is chronically overloaded, a failing breaker, or a panel that has reached the limits of its capacity.
2. Flickering or Dimming Lights
Lights that flicker or dim when appliances cycle on — the HVAC kicks in, the refrigerator compressor starts, the dryer runs — are a sign that your panel is struggling to supply steady power to all of your circuits simultaneously. In a properly sized panel, large appliances drawing current at startup should not noticeably affect the lighting in other parts of the house.
Persistent flickering, particularly when nothing obvious has changed in your household, can also indicate loose connections within the panel itself — which is a fire risk that needs professional attention immediately.
3. Burning Smell or Scorch Marks Near the Panel
A burning smell coming from your electrical panel, or any visible scorch marks or discoloration around breakers or the panel housing, is a serious warning sign that should prompt an immediate call to a licensed electrician. These signs indicate that wiring is overheating — potentially to the point of igniting the insulation around it.
Do not ignore a burning smell from your electrical panel or try to investigate it yourself. Turn off the main breaker if you can do so safely and call a professional. This is not a situation to delay.
4. Breakers That Will Not Stay Reset
A breaker that trips and will not reset, or that trips again immediately after being reset, is either protecting a circuit from a genuine fault in the wiring or has failed internally. In either case, the circuit is not safe to use until the issue has been diagnosed and resolved.
If resetting the breaker provides temporary relief but the problem keeps recurring, the underlying issue — whether it is an overloaded circuit, a failing breaker, or a wiring problem — needs professional diagnosis.
5. Your Panel Uses Fuses Instead of Breakers
Older Myrtle Beach homes — particularly those built before the 1960s — may still have fuse panels rather than modern circuit breaker panels. Fuse panels are not inherently dangerous when they are properly maintained and not modified, but they have significant limitations. They cannot be expanded to support modern electrical loads, they are frequently modified improperly (replaced with the wrong fuse size, bypassed with pennies or foil), and most insurance companies either refuse to cover homes with fuse panels or charge significantly higher premiums.
If your home still has a fuse-based electrical panel, upgrading to a modern circuit breaker panel is a high priority.
6. You Are Planning a Major Renovation or Addition
Adding square footage, renovating a kitchen or bathrooms, finishing a basement or bonus room, or adding a workshop or home office are all projects that add significant electrical load. Before these projects begin, a panel assessment is essential to confirm the existing panel can support the new circuits — and if not, to plan the upgrade as part of the overall project budget.
7. You Are Adding High-Draw Appliances or Equipment
Adding an EV charger, upgrading to a high-capacity HVAC system, installing a hot tub or pool pump, or adding large kitchen appliances all require dedicated circuits with sufficient amperage. If your panel is already near capacity, there may not be room to add the breakers these circuits require without an upgrade.
A panel upgrade is frequently triggered by — and coordinated with — the installation of EV chargers and generators in Myrtle Beach. We regularly handle both projects together to minimize disruption and permitting costs.
8. Your Panel Has Known Safety Issues
Certain panel brands and models manufactured in the mid-20th century have documented safety problems that have led to widespread replacement recommendations from electrical authorities and insurance companies. If you are unsure whether your panel is one of the affected models, a licensed electrician can identify it and advise you on the appropriate course of action.
9. The Panel Feels Warm to the Touch
An electrical panel that feels warm — or hot — on its exterior surface is a warning sign that should be investigated. Some warmth from a panel under normal load is expected, but notable heat often indicates that something is drawing more current than it should, or that there is a connection issue causing resistance and heat buildup within the panel.
10. Your Home Is More Than 25-30 Years Old and Has Never Had a Panel Assessment
If you own a Myrtle Beach home built in the 1970s, 1980s, or 1990s and the electrical panel has never been assessed by a licensed electrician, it is worth scheduling one. Panels from that era were designed for electrical loads that modern households routinely exceed, and components that have been in service for 25-40 years may be approaching the end of their reliable service life.
100-Amp vs. 200-Amp Panels: What Is the Difference?
The amperage rating of your panel determines how much electrical current it can safely distribute throughout your home at any given time.
100-amp panels were the residential standard from roughly the 1950s through the 1980s. For the era they were designed in — homes without central air conditioning, electric dryers, or high-draw modern appliances — 100 amps was sufficient. In today’s homes, a 100-amp panel is a limiting factor for most households.
150-amp panels exist as an intermediate option and are sometimes used in smaller homes or properties with limited utility service capacity. They represent an improvement over 100-amp service but are not the standard for modern residential use.
200-amp panels are the current residential standard and what most electricians recommend for any home upgrade. A 200-amp panel provides sufficient capacity for central air conditioning, electric appliances, EV chargers, home office equipment, generators, and any other modern electrical demand. It also provides room to grow as household needs change over time.
For larger homes or properties with especially high electrical demands — workshops, pool equipment, multiple EV chargers, whole-house generators — 400-amp service or subpanel installations may be appropriate.
What Is Involved in a Panel Upgrade?
A panel upgrade is not a simple project, but it is a well-defined one when handled by a licensed electrician who knows the local requirements.
Assessment and planning. Before any work begins, we evaluate your existing panel, service entrance, and overall load to determine what is needed and confirm the scope of the upgrade.
Permitting. Panel upgrades in South Carolina require an electrical permit and inspection. We handle all permit applications on your behalf. The permit ensures the work is inspected and documented — which protects you as the homeowner and is required for insurance purposes.
Utility coordination. In most cases, the utility company needs to temporarily disconnect service to the home to allow safe removal of the old panel. We coordinate this as part of the project.
Panel removal and installation. The old panel is removed, the new panel is installed and connected to the service entrance, and all existing circuits are reconnected to the new panel. Any new circuits being added as part of the project are installed at this stage.
Inspection. The completed work is inspected by the local authority having jurisdiction to confirm it meets all code requirements.
Power restoration. Once the inspection is passed, the utility restores service and the new panel is fully operational.
The entire process typically takes one to two days for a standard residential panel upgrade. More complex projects with extensive additional work may take longer.
Why Hire a Licensed Electrician for Your Myrtle Beach Panel Upgrade
Panel work is not a DIY project under any circumstances. South Carolina requires electrical permits for panel upgrades, which means the work must be performed by a licensed contractor and inspected before it is considered complete. Unlicensed electrical work is illegal, voids homeowner’s insurance, and creates liability issues if problems arise later.
Beyond the legal requirements, panel work involves working directly with the main service entrance — the point where utility power enters your home. This is live voltage that cannot be safely turned off by the homeowner, and mistakes in this area can be immediately fatal.
