How do I know if my commercial property needs a subpanel upgrade?

Signs your subpanel is undersized include breakers that trip under normal operating conditions, difficulty adding new circuits without overloading existing ones, flickering lights when large equipment cycles on, and physical signs of heat like discoloration or a faint burning smell near the panel enclosure. Many commercial buildings in the Chapel Hill area built in the 1980s and 1990s were wired for 100-amp service. Today's equipment loads routinely exceed that capacity. A trained electrician performs a load calculation per NEC Article 220 to determine whether your existing service can support your actual demand. If you're planning to add equipment, install EV charging stations for fleet vehicles, or expand your space, a subpanel upgrade should happen before you add the load, not after the first failure.

What is the commercial dispatch fee, and what does it cover?

Mr. Electric of Chapel Hill charges a $249 commercial dispatch fee for all commercial service calls. This fee covers the cost of sending a licensed electrician to your location for diagnosis and assessment. The dispatch fee applies separately from the quoted cost of the actual repair or installation work. You'll receive a clear explanation of the work needed and its cost before any labor begins, so you control the decision about what gets done.

How long does a commercial LED lighting upgrade take?

Timeline depends on the number of fixtures, the type of installation, and whether existing wiring supports the new fixtures without modification. A straightforward ballast-to-LED driver conversion on an existing fluorescent fixture takes 20 to 30 minutes per fixture. Replacing complete fixtures, adding new circuits for task lighting, or installing exterior LED upgrades takes longer and may require a permit. Most small to mid-size commercial spaces in Chapel Hill complete a full interior LED upgrade in one to two days. We schedule work during off-hours or weekends when a business can't afford to interrupt operations. LED commercial lighting reduces energy consumption by 50 to 75 percent compared to fluorescent systems, according to the U.S. Department of Energy, making the upgrade cost-effective for businesses paying Duke Energy commercial rates.

Does commercial electrical work in Chapel Hill require a permit?

Yes, most commercial electrical work in Chapel Hill requires a permit issued through Orange County Inspections. Required permits cover new circuit installations, panel and subpanel work, significant wiring modifications, lighting system upgrades in certain cases, and any work affecting the building's service entrance. Simple repairs — such as replacing a failed outlet with an identical unit — typically don't require a permit, but any modification or addition does. Our electricians handle permit applications and schedule required inspections. Permitted work creates a documented record that protects your business during lease renewals, property sales, and insurance claims. Unpermitted electrical work in a commercial building creates liability and can result in violations from the Orange County Inspections Department.

What causes breakers to trip repeatedly in a commercial building?

Repeated tripping usually points to one of three problems: an overloaded circuit drawing more amperage than the breaker is rated for, a short circuit caused by damaged wiring or a faulty device, or a failing breaker that trips below its rated load. In older Chapel Hill commercial buildings, especially those built before 2000, the original electrical infrastructure wasn't designed for today's density of equipment—computers, POS systems, refrigeration units, and HVAC all pulling from circuits sized for much lighter loads. An electrician runs load calculations and either adds dedicated circuits for high-draw equipment or upgrades the subpanel to handle the building's actual demand. The NFPA reports that electrical failures and malfunctions account for roughly 20 percent of structure fires in non-residential buildings annually, making repeated tripping a problem worth addressing promptly rather than resetting and ignoring.

Why Business Owners Choose Mr. Electric of Chapel Hill

You receive a flat-rate quote before any work begins. That price doesn't climb based on how long the job takes or what we find once we start. If we uncover something additional during the work, we stop, explain it, price it, and get your approval before continuing. No surprises when the invoice arrives.
North Carolina commercial electrical work follows the NEC with state-adopted amendments, and commercial properties in Orange County require permits for most electrical modifications. Our electricians help handle permit applications, coordinate inspections, and ensure every installation meets code. This protects your business from liability and keeps your insurance coverage intact. Work performed by an uncertified contractor often fails inspection and voids coverage.
Every job we complete is backed by the Neighborly Done Right Promise^®. If the work isn't done right, we make it right. That guarantee covers commercial electrical projects from a single outlet repair to a full subpanel installation.

What Commercial Electrical Services Does Mr. Electric of Chapel Hill Provide?

Businesses in Chapel Hill run the full range from restaurants in Eastgate to offices near UNC and retail storefronts in Carrboro. Our experienced electricians handle the full scope of commercial electrical work, from day-to-day outlet repairs to full subpanel installations and LED upgrades.

Commercial electrical services we provide include:

Electrical panel and subpanel installation and service: We assess your current load, perform proper load calculations, and install the right panel for your building's demands. Most commercial properties in the Triangle running HVAC, kitchen equipment, and technology infrastructure require at least 200-amp service, and many need a separate subpanel for high-draw zones.
LED lighting installation and replacement: Switching to LED cuts energy use by 75 to 80 percent compared to fluorescent or incandescent sources. For a commercial space running lights eight to ten hours a day, that reduction translates directly to lower Duke Energy bills. We replace existing fixtures and ballasts, install recessed and task lighting, and upgrade exterior and parking area lighting with commercial-grade LED fixtures rated for continuous use.
Outlet installation and repair: Whether you need additional electrical outlets to reduce extension cord reliance or a dead outlet repaired before it affects operations, we handle both quickly. Commercial environments require outlets rated for the load they support, and high-draw equipment should always run on dedicated circuits.
Ballast replacement: Flickering or dim commercial lighting is often a failed ballast rather than the fixture itself. We replace T8 and T12 ballasts and can convert existing fluorescent fixtures to LED drivers at the same time, eliminating future ballast replacements entirely.
Emergency electrical service: Tripped circuit breakers or failed circuit during business hours need a fast response. We provide emergency commercial electrical service throughout Chapel Hill.
