Cornelius Electrical Company serves homeowners, landlords, property managers, and businesses throughout Cornelius and Mecklenburg County with the full range of residential and commercial electrical work. Whether you need a single outlet replaced or a complete service upgrade, we handle the job from diagnosis through final test. We are open daily from 6:30 AM to 10:30 PM, so you can reach us when the problem comes up, not just when it is convenient. Straight scheduling. Upfront pricing. Code-compliant wiring.
From troubleshooting a dead outlet to running new circuits through a finished space, we show up ready to wire. Call us and we'll walk you through the fix.
Some homes need a full rewire. Others just need one outlet fixed. We work across the full range: single-family homes, rental properties, apartment buildings, small offices, retail spaces, and commercial buildings throughout Cornelius and the surrounding area. Homeowners call us for repairs and upgrades. Landlords and property managers call us to bring units up to code before a new tenant moves in. Businesses call us when a circuit trips, when a build-out needs new wiring, or when a panel is no longer keeping up with the load.
When you call, you reach someone who knows the trade and can scope the job on the phone. Hire local and the wiring is done by someone who knows the area. We give honest recommendations on repairs, never an upsell. One call is enough to get the visit booked.
Electrical problems don't wait, and neither do we, so the diagnostic visit is built around finding the root cause rather than just addressing the visible symptom. A dead outlet can point to a loose connection, a tripped GFCI upstream, or a wiring fault in the circuit. Flickering lights can indicate a failing connection at the fixture, a loose neutral in the panel, or a load problem on the circuit. A breaker that keeps tripping or refuses to reset may be overloaded, failing, or responding to a fault elsewhere on the circuit. Half the house losing power or a full outage can signal a service-entrance issue that needs prompt attention. Each symptom tells us something specific, and we follow it to the source.
On a service call, diagnosis comes first. We identify the fault, confirm the scope of the repair, and give you the price before any work begins. AFCI and GFCI protection issues are part of what we check: both circuit types have specific failure modes, and a nuisance trip is different from a protection trip. We keep you informed from diagnosis to final test, so you know exactly what was found, what was done, and what to watch for. Reach out and we'll get it diagnosed.
Doing electrical work right matters, and we'll help you get it right, especially in older homes where the original wiring was never designed for today's loads. Some homes in Cornelius and across Mecklenburg County still carry knob-and-tube wiring, which lacks a ground conductor and was not built for modern circuit demands. Others have aluminum branch-circuit wiring from a later era, which requires specific connection methods to remain safe. Neither is automatically a crisis, but both benefit from a proper inspection and a clear plan for remediation. We assess what is there, explain what it means, and walk you through the options.
A whole-home rewiring job involves pulling new copper branch circuits throughout the home, replacing outdated wiring at every outlet, switch, and fixture location, and bringing the system up to current code. We run a load calculation before the work starts to confirm the panel can carry what the new circuits require. The result is code-compliant wiring throughout, grounded circuits at every location, and a system that is ready for whatever the home needs next. Electrical work done to the standard the next inspection expects is how we approach every rewiring job. Call us and we'll walk you through the fix.
From a single GFCI outlet to a whole-home rewire, the first step is the same: knowing what the job actually requires. Outlet and switch work covers new outlet installation, replacing damaged or outdated receptacles, adding GFCI protection at wet locations like kitchens, bathrooms, and garages, installing dimmer switches, and replacing light switches that have worn out or failed. Each of these jobs improves convenience, brings the location up to code, or both. We confirm the circuit can handle what is being added before the work starts.
Indoor and outdoor lighting installation covers recessed lighting, fixture replacement, landscape lighting circuits, security lighting, and exterior outlet installation. Outdoor lighting is practical for Cornelius properties year-round: it adds visibility at entries and driveways, supports security cameras that need a power source, and extends usable outdoor space into the evening. We handle the wiring and the fixture, not just one or the other.
Ceiling fan installation and replacement rounds out this category. A new fan install involves confirming the ceiling box is rated for fan weight and movement, running or extending the wiring, and connecting the fixture correctly. Replacing an old fan follows the same process. We check the box before the fan goes up, not after. Reach out and we'll get it diagnosed.
Certain appliances draw enough current that sharing a circuit with other loads is not a workable arrangement. Electric dryers, ranges, ovens, and large refrigerators each need a dedicated circuit sized specifically for that load. We run the circuit from the panel, install the correct outlet or connection point, and verify the panel has the capacity to carry it. If it does not, we discuss the panel side of the job at the same time so nothing is left undone.
EV charger installation follows the same logic. A Level 2 home charger requires a dedicated 240-volt circuit with a breaker sized to the charger's output. We run the circuit from the panel to the charger location, size the breaker correctly, and run a load calculation against the existing panel to confirm it can handle the addition. EV adoption in the Cornelius area has grown steadily, and we handle these installs regularly for both homeowners and businesses adding charging for employees or customers. One call is enough to get the visit booked.
Cornelius sits on Lake Norman in a four-season climate that brings both high summer cooling loads and occasional winter ice events. Afternoon thunderstorms are a regular part of summer here, and they produce the kind of surge events and outages that test both panels and protection devices. Older housing stock in parts of the area means panel capacity is a recurring conversation. The three services below come up constantly for that reason. You schedule it. We power it. Simple as that.
A panel upgrade replaces an undersized or aging breaker panel with one that can carry the home's current and future electrical load. That often means upgrading to 200-amp service, replacing a fuse box that was never designed for modern circuit counts, and coordinating the service-entrance and meter work that goes along with it. Older homes in Cornelius and across Mecklenburg County frequently carry panels that were sized for a much lighter load than modern households place on them. Adding an EV charger, a home office, or updated appliances can push an aging panel past its practical limit. We run a load calculation, confirm the scope on the call, and give you the price before anything is scheduled.
Generator installation on the electrical side covers the transfer switch, the connection to the home's critical circuits, and the wiring between the generator and the panel. A properly installed transfer switch keeps the generator isolated from the utility line, which protects both the equipment and anyone working on the line during an outage. Lake Norman's exposure to summer storm systems and the occasional winter ice event means outages are a real and recurring problem for Cornelius homeowners and businesses. We scope and price the electrical side of the installation on the call so you know what is involved before committing to a schedule.
A whole-home surge protection device installs at the main panel and intercepts voltage spikes before they reach the branch circuits. That is a different level of protection than a plug-in power strip, which only covers the devices plugged into it. Afternoon thunderstorm activity around Lake Norman makes surge events frequent throughout the summer months. A single event can damage appliances, electronics, and the power supplies inside HVAC equipment throughout the home. We explain the device, the installation, and what it covers on the call before the visit is scheduled.
An electrical inspection gives you a clear picture of what the system contains and where it stands. For buyers, a pre-purchase inspection covers panel condition, wiring type, grounding and bonding, GFCI and AFCI coverage, and any visible defects in the system before the sale closes. For landlords and property managers, a rental property inspection confirms the unit meets current code requirements and identifies anything that needs attention before a tenancy begins. Sellers use inspections to get ahead of questions that come up during a buyer's due diligence. We document what we find, explain what it means, and give you a clear account of what the next step involves. We keep you informed from diagnosis to final test. Call us and we'll walk you through the fix.
Pricing is straightforward. You get the rate on the phone, and the price is confirmed before anything is scheduled. We go through what the job involves, what access is needed, and what the work covers so the number you hear reflects the actual scope. There are no vague estimates followed by a different figure when the work is done.
Common questions we hear involve the cost to rewire a house, the cost of a panel upgrade, what it runs to install an EV charger circuit, ceiling fan installation cost, the cost to add a dedicated circuit, generator transfer switch wiring cost, and what an electrical inspection costs. The right answer to each of those depends on the scope, and the scope is something we work through on the call. Ask what it covers and you get a straight answer. One call is enough to get the visit booked.
Cornelius is our primary service city, and we work throughout the surrounding communities in Mecklenburg County and the Lake Norman region. That includes Davidson, Huntersville, Mooresville, Denver, Concord, and Kannapolis. Residential and commercial customers across the area can call for a quote on any job, from a single repair to a full-service upgrade.
Breakers that trip frequently, breakers that feel warm or will not reset, a panel that hums or buzzes, visible corrosion or rust inside the panel, and a fuse box that has been modified with the wrong fuse sizes are all signs the panel needs attention. An aging panel that was sized for a lighter load than the home now carries can also show these symptoms without an obvious single fault. A panel inspection identifies what is causing the problem and what the repair or replacement involves.
A whole-home surge protector installs at the main panel and intercepts voltage spikes before they reach the branch circuits and connected devices. Afternoon thunderstorm activity around Lake Norman makes surge events a regular occurrence in the summer months, and a single large spike can damage appliances and electronics throughout the home. It is a different level of protection than a plug-in strip, which only covers the devices plugged directly into it.
A transfer switch isolates the generator from the utility line, which is both a code requirement and a safety necessity. Without a transfer switch, generator power can back-feed the utility line and create a hazard for anyone working on the line during an outage. We install the transfer switch, connect it to the home's critical circuits, and wire the generator connection so the system operates correctly when the power goes out.
An inspection makes sense before buying a home, after a major storm, when a home is being prepared for sale, or when the wiring is old enough that the current condition is not clear. Landlords use inspections before a new tenancy to confirm the unit meets current code requirements. The visit covers the panel, branch circuits, outlets, grounding and bonding, GFCI and AFCI coverage, and any visible wiring concerns.
Knob-and-tube wiring lacks a ground conductor and was not designed for modern circuit loads. Aluminum branch-circuit wiring requires specific connection methods to remain safe, and connections that were made with the wrong hardware can become a problem over time. Neither is automatically an emergency, but both benefit from an inspection and a clear remediation plan before circuits are extended or loads are added.
Diagnosis starts with the reported symptom and works backward through the circuit. That means testing the affected outlets and breakers, checking connections at the device and at the panel, and tracing the circuit to identify where the fault originates. A burning smell, a warm outlet, or a breaker that trips under a specific load each points toward a different part of the circuit, and the inspection follows that evidence to the source.
For most electrical work, the affected circuit is de-energized before any connections are made or changed. Panel work requires shutting off the main breaker or coordinating a utility disconnect depending on what the job involves. We confirm what access and shutdown the job requires on the call so you can plan around it before the visit is scheduled.
Someone with access to the property and the panel needs to be present for the visit. For residential work, that is typically the homeowner or a designated adult. For commercial or rental properties, the property manager or a building contact who can provide access and approve the scope works as well. We confirm the access requirements when the visit is booked.
A burning smell near an outlet usually indicates a loose or failing connection that is generating heat, which is a condition that can progress quickly. A burning smell near the panel can point to a failing breaker, an overloaded circuit, or wiring that has been damaged. Both warrant a call right away rather than a wait-and-see approach.
Call (980) 479-9789 and describe what you are noticing so we can assess the urgency.
After the work is complete, we test the circuits, devices, and fixtures involved in the job to confirm they are operating correctly. For outlet work, that means testing for power and correct polarity. For panel work, it means confirming breaker function and checking the load. We keep you informed from diagnosis to final test, so you know what was done and how it was verified.
In a home with two-wire ungrounded circuits, replacing a two-prong outlet with a three-prong outlet without running a ground wire or installing a GFCI device is a code violation. The correct approach depends on the circuit layout and what the location requires. GFCI protection is one code-compliant method for protecting an ungrounded outlet location, and running a ground wire back to the panel is another where the circuit allows it. We scope the right approach for each location.

| Homeowners and businesses adding Level 2 charging for one or more vehicles | EV charger installs require a dedicated circuit and a panel with available capacity. We scope both on the call so the full picture is clear before the visit is scheduled. |
What are the signs that a home needs a full rewire rather than targeted repairs?
A home that still carries knob-and-tube or aluminum branch-circuit wiring, one that has had repeated unexplained faults across multiple circuits, or one where the wiring has never been updated since original construction are all candidates for a full rewire evaluation. If repairs keep surfacing in different parts of the house, that pattern often points to a systemic wiring condition rather than isolated faults. We assess the system, explain what we find, and give you a clear picture of whether targeted repairs or a full rewire makes more sense for the situation.
What causes a breaker to trip repeatedly on the same circuit?
Repeated tripping on the same circuit usually means one of three things: the circuit is carrying more load than it was sized for, there is a wiring fault somewhere along the circuit that is triggering the protection, or the breaker itself is failing. A breaker that trips under a specific appliance load points toward an overload condition. One that trips without an obvious load change points toward a fault in the wiring or a device on the circuit. We trace the cause before replacing anything, because swapping the breaker without finding the underlying problem leaves the real issue in place.
How does EV charger installation work, and what does the home need to support it?
A Level 2 home EV charger requires a dedicated 240-volt circuit with a breaker sized to the charger's output rating. Before we run the circuit, we check the existing panel for available capacity and run a load calculation to confirm the panel can carry the addition without affecting other circuits. If the panel is already at or near capacity, we discuss the panel side of the job at the same time. We scope the full picture on the call so you know what is involved before anything is scheduled.
Faults Traced Before Anything Is Replaced
We identify the root cause of an electrical problem before recommending a repair. That means honest recommendations on repairs, never an upsell, and no parts replaced that did not need to be.
How does backup generator installation work on the electrical side?
The electrical side of a generator installation covers the transfer switch, the wiring between the generator and the panel, and the connection to the home's critical circuits. A properly installed transfer switch isolates the generator from the utility line, which is both a code requirement and a practical necessity during an outage. Lake Norman's exposure to summer storm systems and winter ice events makes generator hookups a regular request for Cornelius homeowners. We scope and price the electrical side of the installation on the call so you know what is involved before committing to a schedule.
What is involved in a panel or service upgrade, and how long does it typically take?
A panel upgrade replaces an aging or undersized breaker panel with one that can carry the home's current and future load. That work typically involves removing the old panel, installing the new one, transferring the existing circuits, and coordinating the service entrance and meter work that goes along with it. A straightforward panel replacement on a single-family home is generally a full-day job. More involved work, such as a service entrance upgrade or a home with a large circuit count, may run into a second day. We give you a clear scope and timeline on the call before the visit is booked.
Why do outlets and switches stop working even when the breaker has not tripped?
An outlet or switch that has stopped working without a tripped breaker is often caused by a loose or failed connection at the device itself, a tripped GFCI outlet upstream on the same circuit, or a wiring fault between the panel and the device. Many circuits share a GFCI outlet that protects several other outlets downstream, so a tripped GFCI in one room can cut power to outlets in another. We trace the circuit from the device back to the source to identify exactly where the problem is before making any repair.
Code-Compliant Work on Every Job
Every job we complete is wired to the standard the next inspection expects. We confirm code requirements for the specific location and circuit type before the work starts.
What do flickering or dimming lights usually indicate?
Flickering that affects a single fixture usually points to a failing connection at the fixture itself or a problem with the bulb or the outlet. Flickering that affects multiple fixtures on the same circuit suggests a loose neutral connection somewhere in the circuit, which can be at a junction box, a device, or at the panel. Lights that dim when a large appliance starts up are typically responding to a voltage drop under load, which can point to an undersized circuit or a panel that is working close to its capacity. Each pattern tells us something different, and the diagnostic visit follows that evidence to the source.
When should I call an electrician instead of attempting a repair myself?
Any work that involves the breaker panel, service entrance, or wiring inside walls should be handled by someone who knows the trade. Outlet and switch replacement in a straightforward location is something some homeowners attempt, but a mistake at a device can create a fault that is not immediately visible and surfaces later as a more serious problem. Work that requires a permit, any job involving aluminum or knob-and-tube wiring, and anything that involves the panel or service entrance are all situations where calling us first is the right move. We can scope the job on the call and let you know what is involved before you commit to anything.
Scope Agreed Before the Panel Is Opened
We go through what the job involves on the call, confirm the price before anything is scheduled, and keep you informed from diagnosis to final test so there are no questions about what was done or why.
How is surge protection different from a standard power strip, and is it worth adding?
A plug-in power strip with surge protection only covers the devices plugged directly into it. A whole-home surge protection device installs at the main panel and intercepts voltage spikes before they reach any branch circuit in the home. That means appliances, electronics, and the control boards inside HVAC equipment throughout the house are all covered by a single device. Afternoon thunderstorm activity around Lake Norman makes surge events a regular occurrence through the summer months, and a single large spike can cause damage across multiple rooms. We explain the device and what it covers on the call before the visit is scheduled.
How does grounding and bonding work in older homes, and why does it matter?
Older homes with two-wire circuits lack a ground conductor, which means outlets at those locations have no path to carry fault current safely away from a device. That affects both safety and the ability to use modern three-prong equipment correctly. Bonding ties the grounding system together so all metal components in the electrical system are at the same potential, which reduces the risk of a shock between two grounded surfaces. In older Cornelius homes, grounding and bonding conditions vary depending on when the home was built and what updates have been made since. An inspection covers both, and we explain exactly what we find and what the options are.
What is involved in adding circuits for a workshop, home office, or large appliance?
Adding circuits for a workshop, home office, or major appliance starts with confirming the panel has available capacity and the right breaker slots to support the new load. We run a load calculation against the existing panel before any circuit is run. The circuit itself is sized to the load it will carry, run from the panel to the location, and terminated at the correct outlet or connection point. If the panel does not have room, we discuss the panel side of the job at the same time. We scope the full picture on the call so the price you hear reflects everything the job involves.
Call us at (980) 479-9789 to get a quote or schedule a service call. We are open daily from 6:30 AM to 10:30 PM, and we will walk you through exactly what the job involves before anything is booked.
