Three-phase power is essential for businesses that operate large motors, heavy equipment, commercial HVAC systems, and industrial machinery. If your Aiken business needs three-phase power -- whether for a new location, an expansion, or new equipment -- Unity Power & Light handles the entire installation from site assessment through utility coordination, panel installation, wiring, and final inspection.
Three-phase power delivers continuous, smooth power that is fundamentally more efficient for running motors and large loads. Single-phase power pulses 120 times per second, crossing through zero volts each time. Three-phase power staggers three conductors at 120-degree offsets so that power delivery is always near peak. The result is smoother motor operation, higher efficiency, reduced vibration, and the ability to deliver more power with smaller conductors.
Our Installation Process
Site Assessment & Load Calculation
We evaluate your property, catalog all equipment requiring three-phase power, calculate the total electrical load, and determine the appropriate panel and service size. We also verify whether three-phase power is available on the utility's distribution lines at your location.
Utility Coordination
We work directly with your utility provider (Aiken Electric Cooperative, Dominion Energy, or other serving utility) to request three-phase service. If a transformer change or line extension is needed, we coordinate the scheduling and requirements on your behalf. We handle the paperwork so you do not have to navigate the utility's process alone.
Panel & Service Entrance Installation
We install the three-phase meter base, main disconnect, distribution panel, and all associated service entrance equipment. The panel is sized for your current load plus capacity for future growth. All equipment is commercial-grade from manufacturers like Eaton, Siemens, or Square D.
Branch Circuit Wiring
We run appropriately sized conductors from the panel to each piece of three-phase equipment. Circuits are balanced across the three phases to prevent overloading any single phase. All wiring is installed to NEC code with proper disconnects, overcurrent protection, and labeling.
Inspection & Energization
After installation is complete, we schedule the building department inspection. Once passed, we coordinate with the utility to energize the service. Your three-phase power is live and ready for equipment connection.
Businesses That Need Three-Phase
Alternatives When Three-Phase Is Not Available
If three-phase utility power is not available at your location or the extension cost is prohibitive, we can implement alternative solutions:
Rotary Phase Converters
A rotary phase converter generates a third phase from single-phase power, allowing three-phase equipment to operate on single-phase utility service. Practical for businesses with a few pieces of three-phase equipment in areas without utility three-phase.
Variable Frequency Drives
VFDs convert single-phase input to three-phase output for individual motors. They also provide speed control, soft starting, and energy savings. Ideal for powering individual three-phase motors without upgrading the entire service.
