What to Expect: Commercial Electrical Panel Upgrade in Hilton Head Island

Our licensed commercial electrician evaluates the existing service, performs a load calculation that documents current and projected demand, and recommends the right service size for the building’s actual and planned use.
We coordinate every permit through Beaufort County and work with Palmetto Electric Cooperative to schedule the service disconnect that any meaningful upgrade requires.
We design the new panel layout to support current operations and reasonable future expansion, including dedicated circuits for major equipment and capacity for additional tenant fit-outs.
Our crew removes the old panel, installs the new service equipment with code-compliant grounding and bonding, and labels every circuit clearly for facility maintenance teams.
We coordinate the final inspection with Beaufort County and deliver complete documentation suitable for facility records, insurance files, and any tenant or ownership requirements.

How Much Do Commercial Electrical Panel Upgrades Cost in Hilton Head Island?

A standard commercial 200-amp panel upgrade in Hilton Head Island typically runs $3,500 to $8,000 depending on building configuration and service entrance condition, scaling up from the $1,300 to $4,000 residential baseline once commercial conduit, code, and coordination requirements are factored in. A 400-amp commercial service upgrade with new meter base and service drop falls in the $5,000 to $15,000 range, building on the documented $2,000 to $4,000 panel cost for 400-amp equipment. Three-phase service upgrades for larger commercial loads, including the utility coordination and switchgear those projects require, typically land between $8,000 and $25,000.

Three Commercial Panel Issues That Drive Hilton Head Island Upgrades

Three issues drive most of the commercial panel upgrade projects we deliver across Hilton Head Island, each tied to building age, modern equipment loads, or the specific code requirements commercial properties face. Each one rewards planned replacement rather than reactive emergency work.

Commercial buildings on Hilton Head Island accumulate equipment over the years, eventually exceeding what the original service was sized for. Frequent breaker trips during normal operations signal the underlying capacity issue, and the right answer is service expansion rather than continued breaker replacement on an undersized panel.

Commercial buildings carrying Federal Pacific, Zinsco, or Pushmatic panels increasingly fail insurance inspections and tenant lease reviews. SC insurers now require replacement of these panel families before renewing many commercial policies. We replace the equipment, document the upgrade, and deliver insurance-ready paperwork.

Restaurants adding commercial walk-in cooler equipment, retail spaces installing larger HVAC systems, and offices adding heavy IT loads sometimes need to convert to three-phase service from single-phase. We coordinate the utility-side work, install three-phase switchgear, and configure the building’s electrical for the new service. Pair with commercial electrical installation when the conversion includes new equipment circuits.

Summit Services: Hilton Head Island’s Commercial Panel Upgrade Specialists

Summit Services delivers commercial electrical panel upgrades across Hilton Head Island and Bluffton, serving restaurants, hotels, retail spaces, offices, and medical buildings. We are fully licensed, insured, and bonded for commercial work, we pull every required permit, and we back every panel install with a 3-year warranty. Call 843-738-2464.

How long does a commercial panel upgrade take?

Most commercial 200-amp upgrades finish in one to two days once permits are in hand and the utility disconnect is scheduled. Larger 400-amp and three-phase service upgrades typically run two to four days. We coordinate the work around your operating hours when possible.

Will my business lose power during the upgrade?

Yes, briefly. We coordinate the service disconnect with Palmetto Electric Cooperative across Hilton Head Island to minimize downtime, typically completing the panel swap within four to six hours. After-hours and weekend scheduling can move the outage outside your operating window when possible.

Do you handle three-phase service upgrades?

Yes. Three-phase service applies to commercial buildings with significant motor loads, larger HVAC equipment, or equipment specifically requiring three-phase power. We coordinate with the utility for service-side modifications during these projects.

What about Federal Pacific or Zinsco commercial panels?

SC insurers increasingly require replacement of these panels on both residential and commercial properties. We replace them with modern UL-listed equipment, upgrade grounding and bonding to current code, and document the work for your insurance file. Coordinate with commercial circuit breaker installation when new dedicated circuits accompany the upgrade.

Our commercial panel upgrade work covers 100-to-200-amp single-phase upgrades, 200-to-400-amp commercial expansions, and three-phase service upgrades coordinated with the utility. We also replace main service entrances and meter bases, bring grounding and bonding up to current NEC, install sub-panels for tenant fit-outs and equipment areas, relocate panels during renovations, and provide the documentation property managers and ownership groups need for capital records. Pair with commercial electrical panel services when inspections, sub-panels, or specialty work supplement the upgrade scope.

Commercial panels age out in two ways: the load outgrows them, or the components do. These are the scenarios put a panel upgrade on the project list:

The building has added equipment loads beyond what the existing service supports.
Breakers trip frequently during normal operations.
An insurance inspection has flagged the existing panel for replacement.
A tenant fit-out demands more dedicated circuits than the current service can accommodate.
EV charging or generator integration requires expanded service capacity.
The panel has reached the age where component failures and replacement-part scarcity favor full replacement.
