Our Services

We handle sub panel installations for Charleston homes and properties of all sizes, from minor upgrades to full capacity expansions.

New Sub Panel for Home Additions

Adding a bedroom, garage, or office? A dedicated sub panel in Charleston distributes power efficiently to new circuits without overloading your main service.

New additions need reliable power routing. We size the sub panel and feeder cable based on your planned loads and Charleston building code requirements, so your new rooms operate safely from day one.

Workshop and Garage Sub Panels

Workshops and garages demand dedicated circuit power for tools and equipment. A sub panel in Charleston lets you run heavy loads without tripping breakers or running long extension cords across your property.

We install sub panels with proper grounding, bonding, and breaker configuration so your tools, air compressors, and welders have clean, protected power.

Upgraded Appliance and HVAC Circuits

New heat pumps, electric dryers, or EV chargers need significant electrical capacity. A sub panel in Charleston isolates these high-demand appliances into dedicated circuits, protecting your home's main service panel.

We ensure proper breaker ratings, wire gauge, and disconnects for each appliance. Your sub panel also gives you flexibility to add future circuits without a complete main panel upgrade.

Why It Matters

A properly installed sub panel protects your home, meets code, and supports future growth without expensive main service upgrades.

Safety and Code Compliance

Charleston's electrical code is strict about grounding, bonding, and breaker sizing. We pull permits and coordinate with inspectors to ensure your sub panel passes every safety check and earns final approval.

Unpermitted electrical work can void insurance claims and create fire hazards. We handle permits so your sub panel is legally compliant and fully protected.

Capacity for Growth and Flexibility

A sub panel adds circuit space without upgrading your main service. Whether you're adding a heat pump next year or an EV charger later, your sub panel grows with you.

We design sub panels with extra breaker slots and proper conduit sizing so future circuit additions are fast and affordable.
