Commercial Electrical Panel Upgrades in Myrtle Beach, SC
Plan business power around equipment voltage, phase, capacity and the shutdown window that keeps your operation organized.
What the Work Involves
Assess demand and equipment
Review existing loads, service ratings and the condition of the panel or service equipment.
Plan the supply and interruption
Define equipment ratings, feeder routes and any utility-controlled disconnection before scheduling.
Confirm scope, permits and scheduling
We identify permit and inspection requirements for the property jurisdiction. Utility coordination is included when the work affects its equipment or supply. You receive the proposed scope before approving the work.
Complete the work and check operation
We complete the agreed electrical work, test the relevant installation and explain operation, findings and any follow-up. Required official inspections are a separate part of completion.
Read the equipment requirements first
Restaurant machinery, motors, HVAC systems and production equipment can require different supplies. A 208V three-phase load and a 240V single-phase appliance are not interchangeable just because their power ratings look similar. We review nameplates and installation instructions, the existing distribution and the utility supply before specifying connections.
Plan an occupied-site shutdown
List the refrigeration, alarms, computers, process equipment and tenant operations affected. An authorized site contact helps establish access, isolation and return-to-service responsibilities. Shared buildings may need landlord approval and coordination with other tenants. A safe interruption plan is part of the job, not an afterthought.
Define the handover
The agreed work can include equipment identification, updated circuit directories, electrical checks and coordination with vendor startup. An electrical connection does not automatically complete a machine supplier’s commissioning. For commercial kitchens or motor controls, we identify those responsibilities in advance.
Equipment ratings, routing, access, outage constraints and the condition of existing distribution shape the price. Send nameplate photos and your operating schedule to start a useful conversation.
Details that help us plan your project
- Current panel information and available electrical schedules
- Existing equipment and planned tenant or machinery loads
- Critical operations and acceptable shutdown windows
- Facility approval contact, utility provider and project drawings
Common questions before booking
Can you create three-phase power with a new panel?
A panel does not change the utility supply by itself. The available service and any engineered conversion arrangement must be evaluated for the equipment.
Can a business stay open during a commercial panel upgrade?
Some preparation may be possible outside occupied areas, but transferring or isolating affected circuits can require a planned interruption. Share opening hours, refrigeration, critical equipment and access restrictions. Guardian identifies the proposed shutdown, utility involvement and project responsibilities before scheduling; uninterrupted operation is not assumed.
Can I get more electrical capacity just by putting in a bigger panel?
A larger panel does not by itself increase the capacity of the incoming electrical service. The utility supply, meter equipment, conductors and protective devices must support the proposed arrangement. Main service lugs, the terminals where incoming power connects, may remain live with the main breaker off; keep covers closed.
Will the power need to be turned off while this electrical work is done?
The required power interruption depends on the equipment and scope. We identify affected circuits, safe isolation arrangements and any utility-controlled disconnection before scheduling. Tell us about medical equipment, refrigeration and occupied business operations.
What makes commercial panel-upgrade prices differ?
The existing distribution arrangement, voltage and phase requirements, equipment loads, shutdown sequence and access can change the work. Utility changes, tenant coordination, temporary arrangements and vendor involvement should be identified separately. Compare proposals for the same equipment and operating constraints rather than only the panel rating.
How are the quote and diagnostic charges handled?
Guardian offers free quotes for planned projects. A fault-finding visit or service call can involve a diagnostic charge, explained before booking. Access, equipment requirements and the work identified determine the proposed repair or installation scope.

Repair & troubleshooting
What does the repair assessment cover?
Share the affected distribution equipment, business operations and equipment that cannot lose power unexpectedly. Diagnostic work and any repair shutdown are coordinated with the property contact and applicable utility requirements.
Could replacement or specialist service be needed?
The electrical proposal should identify the distribution equipment, affected loads and agreed isolation or shutdown. Equipment-vendor repairs, utility changes and work outside that distribution scope are not automatically included. Operating hours, tenant access and critical loads can affect the sequence and price.
Protect the operating plan during commercial fault assessment
Identify affected panels or equipment and provide available schedules, fault history and recent changes. Tell us which operations or tenant areas need advance notice before power can be interrupted. Available drawings and an authorized facility contact make the assessment more specific.
The findings distinguish a compatible component replacement, circuit repair, distribution change or utility issue. Define any shutdown, temporary operating arrangement and equipment-provider involvement before work proceeds. A full upgrade should follow the actual need rather than the size of the building alone.
Heavy-ups and distribution changes
A commercial heavy-up is a supply and capacity planning project, not simply an enclosure with more breaker positions. Identify existing loads, proposed equipment, available records and any supply limitations. The accepted scope may involve panelboards, feeders, meter equipment or utility coordination; each element should be identified before a shutdown is promised.
Switchgear, busway, transformers and service equipment can require specialist assessment or engineering responsibilities. Name the actual equipment in the enquiry so Guardian can review the required qualifications and accepted electrical scope instead of treating every distribution product as a standard panel replacement.
Questions about this electrical work
Why can business expansion require an electrical capacity review?
New machinery, cooking equipment, HVAC, charging or lighting can change the demand on the existing distribution. Breaker space does not establish spare capacity. Provide the complete proposed equipment schedule and growth plan so the electrical assessment can consider the building supply and required changes together.
