About this file
This Statement of Work (SOW) details electrical connection requirements for two industrial-grade water chillers at the USGS Tunison Laboratory of Aquatic Science in Cortland, NY. The project involves installing dedicated electrical circuits to connect two new water chillers located outside the laboratory, requiring 145 feet of electrical cable and conduit from the existing electrical panel. Specific technical requirements include installing two circuit breakers, running 3-phase electrical circuits, mounting NEMA 3R safety disconnect switches, properly grounding the chillers, and ensuring electrical compatibility with the chillers' specifications (208/230V, 3-phase, 143 FLA, 178 MCA, 250 MOP).
The solicitation (No. 140G0225Q0077) is issued by the Department of the Interior US Geological Survey Office of Acquisitions and Grants, seeking a licensed electrician to complete the installation. Key deliverables include connecting the water chillers to the electrical panel on dedicated circuits, running electrical cable and conduit through the laboratory attic, installing safety disconnect switches, and testing the water chillers to verify proper electrical connection. Performance standards require safe operation and provision of 208V 3-phase power to the chillers, with onsite observation to verify compliance.

USGS Tunison Laboratory of Aquatic Science 3075 Gracie Rd., Cortland NY 13045 Electrical Connection of Water Chillers
1.0 Introduction and Background
Introduction: USGS, Great Lakes Science Center’s, Tunison Laboratory of Aquatic Science in Cortland NY needs two electric (208/230/3/60: 143 FLA || 178 MCA || 250 MOP) industrial grade water chillers wired and tested by a licensed electrician.
Background: The USGS Tunison Laboratory of Aquatic Science has two (2) industrial grade water chillers that are used for fisheries research. The electric water chillers are brand new, sit outside of the laboratory on a 5-inch thickness concrete pad, and are in position to be hooked up to the electrical system at the laboratory. To provide power to the two water chillers, dedicated circuits need to be established. This includes running electrical cable and conduit from the electric panel inside of the laboratory, to the location of the chillers outside of the laboratory (145 feet). The chillers operate on 208/230 volt – 3-phase electrical power (208/230/3/60: 143 FLA || 178 MCA || 250 MOP).
2.0 Scope
The existing electrical panel (208V 3-phase) has capacity to hookup both water chillers, however, two (2) dedicated circuits will need to be installed to each water chiller. New breakers and mounting kits will need to be installed and rated for each chillers electrical requirements (208/230/3/60: 143 FLA || 178 MCA || 250 MOP; and see attached water chiller electrical specifications). Electrical cable and conduit pipe will need to be run from the existing electrical panel inside of the laboratory 145 feet to each water chiller (see attached Upper Lab map). Penetrations will need to be made in the exterior concrete block wall to run electrical cable and conduit pipe. A National Electrical Manufacturers Association (NEMA) 3R safety disconnect switch will need to be installed at the termination of each circuit, which should be attached to the building exterior near each chiller’s wiring panel. Each circuit will be labeled with the voltage, phase, and amperage at each termination. Each chiller will need to have an electrical ground installed according to local codes. Each chiller will need to be tested to verify proper electrical connection.

4.0 Technical Requirements
Connection of water chillers to electrical panel –
· Circuit breakers (2) and electrical cable capacity will need to be determined to accommodate 178 MCA before installation (see water chiller specification sheet and length of run from panel to chiller).
· Conduit pipe will need to be sized to accommodate two (2) 3-phase electrical circuits and run through the laboratory attic (145 feet).
· Two (2) safety disconnect switches to accommodate 250 MOP (see water chiller specification sheet) will need to be installed and tested at each water chiller.
· Both circuit will be labeled with the voltage, phase and amperage at each termination.
5.0 Deliverables
Major tasks include:
· Connecting two water chillers to electrical panel on dedicated (2) circuits.
· Testing water chillers.
