1.0 Background & Objective

Coast Guard Academy requires an inspection, fuse replacement, component repair, and testing of existing Eaton/Cutler-Hammer MVS2 Medium Voltage Switchgear (13.2 kV), as well as insulation resistance testing on a specific 15kV feeder cable. Parts have been previously cannibalized from certain cabinets, requiring a certified electrical contractor to assess, procure, and install replacement

OEM components to restore full operational capability.

2.0 Equipment Specifications

Specification Value

Equipment Type Eaton/Cutler-Hammer MVS2 Load Interrupter Switchgear

System Voltage 13.2 kV

Fuse Type Eaton 15CLE-250E (15.5 kV, 3-inch Single Barrel)

Style Number (Reference) 1A33843G26

3.0 Scope of Work: Cabinet 5 Maintenance, Testing, and Re-

energization

The Contractor shall provide all labor, materials, equipment, and supervision to perform the following:

3a. Inspection: Thoroughly inspect all parts and components within Cabinet 5 to ensure safe operation.

Note any damaged parts.

3b. Fuse Replacement: Safely remove the existing fuses and install three (3) new Eaton 15CLE-250E fuses in Cabinet 5.

3c. Feeder Cable Testing: Perform Insulation Resistance (Megger) testing on the 15kV feeder cable running from Switchgear Cabinet 5 to its termination point at Smith Hall. Testing shall be performed in accordance with current ANSI/NETA ATS/MTS standards. Provide a certified test report detailing the resistance readings and pass/fail criteria. If testing requires a building shutdown, coordinate with the Contracting Officer’s Representative (COR).

3d. Re-energization: Safely put Cabinet 5 and the associated feeder line to Smith Hall back online.

3e. Spares: Procure and deliver three (3) extra Eaton 15CLE-250E fuses to the site point of contact to be kept as on-site spares.

H. It is highly recommended that the Contractor visit the job site and visit the building in order to determine what is reasonable or necessary to ascertain the nature and location of the work to be performed in general, and the local conditions which can affect the work or the cost thereof. Failure to do so will not relieve the Contractor of his responsibility for estimating properly the difficulty or cost of successfully performing the work.
