Upgrading an electrical panel is one of the most impactful improvements you can make to a home or commercial property — and it is also one of the projects that generates the most questions. Whether you are dealing with a panel that is out of space, preparing for a major appliance addition, or coordinating a full 200-amp service upgrade with the utility, there is a lot to understand before the work begins.
Below, the CMC Electric team answers the panel upgrade questions we hear most often from homeowners and business owners across Raleigh, Clayton, and the Triangle. If your question is not covered here, call us or book an appointment online and we will walk you through it.
Several licensed electrical contractors in Raleigh perform panel upgrades, so the decision usually comes down to licensing, experience, and how the contractor handles the details around your project. Start by verifying that the electrician holds an active license with the North Carolina Board of Examiners of Electrical Contractors — you can check any contractor’s status directly on the NCBEEC website. From there, ask whether they pull their own permits through the City of Raleigh, whether they schedule the required inspection on your behalf, and whether they provide a written estimate with an itemized breakdown of labor and materials.
At CMC Electric, panel upgrades are one of our most-requested services. We have performed hundreds of panel replacements and upgrades across Raleigh, Garner, Cary, Apex, and the surrounding Triangle area since 2005. Every project includes a written quote, full permit handling, and our lifetime craftsmanship warranty. We recommend asking any contractor you are considering for at least two or three recent panel upgrade references so you can hear directly from other homeowners about how the job went.
A 200-amp service upgrade is more than just swapping out your breaker panel. In most cases, the project involves replacing the electrical panel itself, upgrading the meter base (the enclosure where the utility’s meter connects to your home), installing a new service entrance cable rated for 200 amps, and upgrading the grounding system to meet current code. Because the utility company owns the meter and the connection to the power line, your electrician needs to coordinate a temporary disconnect so the meter can be pulled, the meter base replaced, and the new equipment energized and inspected before the utility reconnects service.
In the Raleigh area, this coordination typically involves Duke Energy or the local municipal utility. CMC Electric handles the full process — we submit the permit application to the City of Raleigh, schedule the disconnect with the utility, complete the upgrade, arrange the inspection, and confirm reconnection. Most 200-amp residential upgrades are completed in one to two days of on-site work, though permit and utility scheduling can add a few days on either side. We will give you a clear timeline before we start so you know exactly when to expect a brief service interruption.
Yes. Commercial service upgrades follow a similar process to residential upgrades but often involve higher amperage, three-phase power, and more complex utility coordination. A small business that is adding equipment, expanding square footage, or converting a space may need to step up from 100-amp or 200-amp single-phase service to a 200-amp or 400-amp three-phase service, depending on the load demand.
The first step is always a site visit and load calculation. Your electrician should review the existing service size, assess the current and projected demand from lighting, HVAC, equipment, and any planned additions, and then determine whether the existing service can handle the load or needs to be upgraded. For larger commercial upgrades, the utility may require engineered drawings or a formal service application before scheduling the work.
CMC Electric serves both residential and commercial clients throughout Raleigh and the Triangle. For commercial service upgrades, we perform the load calculation, prepare the permit application, coordinate directly with the utility on disconnect and reconnection scheduling, and manage the inspection process. If your business operates on a tight timeline, we will work with you to minimize downtime and stage the work so critical systems stay online as long as possible.
An electrical load calculation is a formal assessment of how much power your home’s electrical system is currently using and how much additional capacity is available. It takes into account every circuit and major appliance connected to your panel — your HVAC system, water heater, dryer, range, and any other large draws — and compares the total demand against the rated capacity of your electrical service. The calculation follows a standard method defined in the National Electrical Code.
You should have a load calculation performed any time you are planning to add a significant electrical load to your home. Common triggers include installing an EV charger, adding a whole-house generator, converting from gas to electric appliances, finishing a basement, or building an accessory dwelling unit. If the calculation shows that your existing panel and service can handle the new load, you may only need a new dedicated circuit. If it shows that you are at or near capacity, a panel upgrade or service upgrade may be necessary before the new equipment can be safely installed.
CMC Electric includes a load calculation as part of any project that involves a significant addition to your home’s electrical demand. We will review the results with you, explain your options, and give you a clear recommendation before any work begins — so you are never surprised by the scope or cost of the project.
Panel labeling is the process of clearly identifying which circuit breaker controls which area or appliance in your home. It sounds simple, but a surprising number of panels in the Raleigh area are unlabeled, mislabeled, or labeled with faded handwriting that is impossible to read. Accurate labeling is a code requirement and a practical safety measure — it allows you or an electrician to quickly shut off the right circuit during an emergency or repair.
Circuit rebalancing and load balancing refer to redistributing the electrical loads across the two bus bars (called “legs”) inside your panel so that power draw is roughly even. When one leg carries significantly more load than the other, it can cause voltage imbalances, flickering lights, and premature wear on equipment. Rebalancing involves moving circuits from the overloaded leg to the underloaded one, which sometimes requires physically relocating breakers within the panel.
These services are especially valuable if you have added circuits over the years without a system-wide review, if you are experiencing dimming or flickering that is not tied to a single fixture, or if you are preparing for a home sale and want your panel to pass inspection cleanly. CMC Electric performs panel labeling and load balancing as standalone services or as part of a broader panel upgrade — and we include a labeled panel directory card with every job so you always know what each breaker controls.
The meter base — sometimes called the meter pan or meter socket — is the enclosure mounted on the exterior of your home or building where the utility’s electric meter sits. It connects the utility’s incoming power line to your service entrance cable and ultimately to your electrical panel. Over time, meter bases can corrode, develop loose connections, or simply become outdated and incompatible with modern metering equipment.
You will typically need a meter base replacement in one of three situations: you are upgrading your service from 100 amps to 200 amps and the existing meter base is not rated for the higher amperage; the utility has flagged your meter base as damaged or non-compliant during a routine read or inspection; or your meter base has physically deteriorated due to weather, corrosion, or age. In all three cases, the work requires coordination with the utility because the meter must be pulled before the base can be replaced and reinstalled.
CMC Electric handles meter base replacements across Raleigh and the surrounding area. We pull the permit, contact the utility to schedule the meter disconnect, replace the base with a unit that meets current code and utility specifications, and coordinate the inspection and reconnection. The actual on-site work is usually completed in a few hours, though utility scheduling can add a day or two to the overall timeline. We keep you informed at every step so you know exactly when the brief service interruption will happen.
Any time your electrician needs to work on the meter base, the service entrance cable, or the main breaker, the utility’s meter must be removed first. This is not something your electrician does unilaterally — the utility company (typically Duke Energy in the Raleigh area) must be contacted in advance to schedule a meter pull, and in many cases the utility sends a technician to remove and later reinstall the meter.
The typical sequence looks like this: your electrician submits a permit application and schedules the work; the utility is notified and a disconnect date is set; the utility pulls the meter on the scheduled day; your electrician completes the panel swap, meter base replacement, or service upgrade; the city inspector performs the required inspection; and once the inspection passes, the utility reinstalls the meter and restores power. In straightforward cases, the power outage lasts only a few hours on the day of the swap.
For remodels that involve a panel relocation or a full service upgrade, the timeline may be slightly longer because additional wiring, trenching, or conduit work is required before the meter can be reconnected. CMC Electric coordinates this entire process from start to finish. We handle the permit, schedule the utility disconnect, complete the electrical work, arrange the city inspection, and confirm the reconnection — so you have a single point of contact instead of juggling calls between your electrician, the permit office, and the utility.
The timeline depends on the scope of the project. A straightforward panel replacement — where the service size stays the same and the meter base does not need to be swapped — can often be completed in four to six hours of on-site work. A full 200-amp service upgrade that includes a new meter base, service entrance cable, grounding, and panel typically takes one to two full days on site.
In both cases, there will be a period without power. For a simple panel swap, the outage is usually limited to a few hours while the old panel is disconnected and the new one is wired and energized. For a service upgrade involving a meter pull, the outage begins when the utility removes the meter and ends when the inspection passes and the utility reconnects — which is usually the same day if the inspection is pre-scheduled, or the following business day in some cases.
CMC Electric minimizes disruption by pre-staging materials, scheduling the utility and inspection before we arrive, and keeping you informed of the timeline so you can plan around the outage. If you work from home or have medical equipment that requires power, let us know when you request your estimate and we will build a plan that accounts for those needs.
Yes. Electrical panel upgrades require a permit in Raleigh and throughout Wake County. The permit ensures that the work is reviewed by a city electrical inspector to confirm it meets the current North Carolina Electrical Code. Performing panel work without a permit can result in fines, complications during a home sale, and — most importantly — safety risks from uninspected wiring.
The inspection process is straightforward. After your electrician completes the upgrade, the city inspector visits the property and checks that the panel is properly rated, the breakers are correctly sized for their circuits, the grounding and bonding meet code, all connections are tight and properly torqued, and the panel is labeled. If everything passes, the inspector signs off and the permit is closed. If there are corrections needed, the inspector will note them and your electrician returns to address the items before a reinspection is scheduled.
CMC Electric manages the entire permit and inspection process on every panel project we perform in Raleigh. We submit the application, pay the fee, provide you with the permit number for your records, and schedule the inspection. Our lifetime craftsmanship warranty means that if a correction is ever needed on our work, we handle it at no additional cost to you.
