Metro State Hospital - 4160V Starter Upgrade

The project at the Metro State Hospital in Norwalk, California, involves upgrading the electrical protection system for a 1000 KVA temporary transformer that powers a rental chiller in the Co-Gen Building. The current protection setup is inadequate, as its existing current transformer ratio of 100:5A and 200A medium voltage fuse do not provide sufficient safeguarding when the chiller operates at full capacity. To resolve this, the transformer’s current transformer ratio will be increased to 200:5A, and the existing fuse and overload relay will be replaced with appropriately rated components to ensure complete and reliable protection under maximum load conditions. The upgrade is critical to prevent equipment damage and service disruptions, aligning the protection system with the actual operational demands of the chiller. The project is listed as a forecast under the California State Hospitals, Department of, with a posting date of June 15, 2026. The primary point of contact for inquiries is Crystal Zhang, Associate Construction Analyst, and Gonzalo Caceres, Construction and Maintenance Supervisor, both reachable via email and phone provided. The work will be performed on-site at the hospital facility in Norwalk, California, and no specific set-aside or NAICS code has been designated at this stage.
