Scope of Work
The dual-input switchboard, capable of sourcing power from both utility and generator inputs, was designed to feed two 1MW uninterruptible power supplies (UPS). These UPS units were paralleled to provide a 3000A UPS-backed output, guaranteeing continuous operation even in the event of power fluctuations. To optimize space and reduce wiring congestion, all connections were seamlessly integrated within the skid base, enhancing the efficiency and reliability of the system.
Challenges & Solutions
Cooling was a key consideration in the design, with each module featuring an exterior mixing box that leveraged outside air for thermal management. This approach not only improved energy efficiency but also maintained optimal operating conditions for the electrical components. Each module measured 48 feet by 13 feet by 12 feet and weighed 110,000 pounds, requiring precise logistical planning for transportation and installation.
Results
To ensure seamless deployment, all six modules underwent rigorous testing, including startup, load bank testing, and commissioning to Level 3 standards within the facility. Each unit was CE marked, structurally braced, meticulously packaged, and shipped overseas to the project site. Through its expertise in modular electrical solutions and commitment to quality, Cummings Electrical successfully delivered a robust and scalable power infrastructure tailored to the HPC site’s high-performance demands.
