TECHNICAL SPECIFICATIONS

TECHNICAL SPECIFICATIONS

ICE HARBOR LOCK AND DAM

480V Breaker/Bucket Replacement for SU and CQO Motor Control Centers

1.0 BACKGROUND

480V motor control centers (MCCs) for generators and auxiliary systems were installed when Ice Harbor Lock and Dam was built. The breakers and control systems in these MCCs are failing and replacement parts are difficult to locate or can’t be purchased. Installing new components into an existing MCC compartment (bucket/unit) can require modifications or may not fit. Replacing the entire bucket is easy to implement and cost less when accounting for labor. The following specifications pertain to the purchase of 480V buckets and main breakers for existing MCCs to replace failing components.

3.2.4 Control-Circuit Transformers

Provide control-circuit transformers within the enclosure of magnetic contactors and motor controllers when the line voltage exceeds 120V.

Provide an encapsulated dry-type, single-phase, 60-Hz transformer, with a 120V (or 24V) isolated secondary winding. Do not provide a transformer with a rated primary voltage less than the rated voltage of the controller, or a rated secondary current less than the continuous-duty current of the control circuit.

Provide voltage regulation of the transformer such that, with rated primary voltage and frequency, the secondary voltage is not less than 95 percent nor more than 105 percent of rated secondary voltage.

Provide a source of supply for control-circuit transformers at the load side of the main disconnecting device. Protect the secondary winding of the transformer and control-circuit wiring against overloads and short circuits, with fuses selected in accordance with NEMA ICS 6. Ground the secondary winding of the control-circuit transformer in accordance with NEMA ICS 6.

3.2.5 Control Relays

Provide magnetic control relays for energizing and de-energizing the coils of magnetic contactors or other magnetically operated devices, in response to variations in the conditions of electric control devices in accordance with NEMA ICS 1, and NEMA ICS 2.

Ensure that the core-and-coil assembly operates satisfactorily with coil voltages between 85 percent and 110 percent of their voltage rating.

Provide relays that are designed to accommodate normally open and normally closed contacts.

Provide 120V, 60-Hz, magnetic control relays with a continuous-contact rating of 10 A, and with current-making and -breaking ability in accordance with NEMA ICS 1 and NEMA ICS 2, two normally open and two normally closed.

3.2.6 Pushbuttons

For low-voltage AC full-voltage magnetic pushbutton controllers, provide heavy-duty, oil-tight NEMA 250, momentary-contact devices rated 600 V. Pushbuttons shall be non-illuminated with a button color of black or red for “Run” and green for “Stop”.

Provide pushbuttons that are designed with normally open, circuit-closing contacts; normally closed circuit-opening contacts; and two-circuit normally open and normally closed circuit-closing and -opening contacts.

Ensure that pushbutton-contact ratings are in accordance with NEMA ICS 1 and NEMA ICS 2, with contact designation A600.

Identify pushbuttons in door with identification plates affixed to the front cover in a prominent location.

3.2.7 Selector Switches

Provide heavy-duty, oil-tight, maintained-contact selector switches for low-voltage control circuits, with the number of positions and the marking of identification plates in accordance with NEMA ICS 1 and

NEMA ICS 2.

Identify selector switches in door with engraved identification plates affixed to the front cover in a prominent location.

3.2.8 Indicating Lights

Provide oil-tight indicating lamps with flush mounted base and translucent convex lens. Red light indicates “Run” and green light indicates “Stop”.

3.3 Execution

Standard factory tests shall be performed on the equipment provided under this section. All tests shall be in accordance with the latest version of NEMA and UL standards.

4.0 SUBMITTALS

Vendor shall submit with its quote detailed product information, to include manufacturer cut sheets and manufacturer and/or vendor drawings and diagrams showing any needed product alteration or customization.

Product data must provide sufficient detail to demonstrate that the proposed product(s) are capable of integrating seamlessly with Ice Harbor Project’s existing system(s). Information shall be submitted to the technical point of contact at site (through Contracting Office), for technical approval. Submittals are due within 15 calender days of contract award.

Approval of the material submitted shall in no way relieve the Contractor from the responsibility of complying with the requirements of the specifications as to the suitability and quality of materials and workmanship.

5.0 WARRANTY

All items shall be covered by the manufacturer’s standard warranty on all parts, labor, and workmanship from factory defects.

6.0 OPERATION AND MAINTENANCE MANUALS

Three (3) complete hardcopies and one (1) electronic copy of the Operation and Maintenance Manuals (O&M Manuals) shall be submitted for the MCC buckets and main breakers. The O&M Manuals shall include order-specific instructions on the installation, maintenance, repair, troubleshooting, warranty, and a list of recommended spare parts (if applicable). Any information pertaining to models or components not supplied under this contract shall be crossed out.

The O&M Manuals shall also include a sheet at the front of the manuals listing the name, phone number, contact information for the manufacturer, and a distributor where spare parts can be purchased. The complete contract award number (as found on the contract Award document) shall also be included.

7.0 SHIPMENT AND DELIVERY

Perform delivery, handling, and storage of items conforming to the manufacturer's requirements and best industry practices. The Government will assist with unloading the items at the site. Verify the condition and quantity of the items upon delivery by the Contracting Officer and acknowledge receipt and condition thereof in writing. If delivered items are damaged or a shortage is determined, notify the Contracting Officer of such in writing within 24 hours after delivery.

All items shall be delivered FOB to Ice Harbor Lock and Dam by Aug 31, 2022 or within 8 weeks after approval of all submittals. The Contractor shall be responsible for packing and shipping the items in a manner that will ensure undamaged and complete arrival to the Project site. No shipments are allowed other than normal business hours of Monday thru Thursday 7:00 a.m. to 4:00 p.m., excluding federal holidays.

All shipments shall be delivered to:

Ice Harbor Lock and Dam 2763 Monument Drive Burbank, WA 99323
