Electrical Panel & Service Upgrades in Charleston, SC
Buildings accumulate load. A restaurant adds equipment, an office fills with workstations, a tenant moves in with requirements the original service was never sized for. Eventually the panel becomes the constraint — or the hazard.
SouthTech Electric performs service and panel upgrades for commercial and residential properties from Charleston to Columbia, bringing capacity and code compliance up to what the building actually needs today.
Panel & Service Work
-
Service upgrades
Increasing incoming service capacity, coordinated with the utility, for buildings that have outgrown their original sizing.
-
Panel and subpanel replacement
Replacing obsolete, overloaded, or recalled distribution equipment with modern panels that meet current code.
-
Circuit additions
Dedicated circuits for kitchen equipment, HVAC, server rooms, EV charging, and other high-draw additions.
-
Load studies
Measured assessment of what the building draws before recommending what it needs — not a guess based on square footage.
-
Code correction
Bringing existing distribution into compliance ahead of an inspection, sale, or insurance requirement.
Common Reasons Buildings Need an Upgrade
- New tenant or equipment load the original service cannot support.
- Federal Pacific, Zinsco, or other obsolete panels flagged by an inspector or insurer.
- Repeated nuisance tripping that is a capacity problem, not a breaker problem.
- Planned additions — EV charging, kitchen expansion, server or IT load.

Frequently Asked Questions
- How do I know if my building needs a panel upgrade?
- Repeated breaker trips, no space for additional circuits, visible corrosion or heat damage, or an obsolete panel brand flagged by an inspector or insurer are all common indicators. A load study gives you a definitive answer.
- Will the power need to be shut off?
- Yes, for part of the work. For commercial properties we schedule the outage window around your operating hours — often overnight or on a weekend — to minimize disruption.
- Do you handle the permits and utility coordination?
- Yes. Permitting and coordination with the utility for a service upgrade are handled as part of the project.
