The successful bidder and City of Rosenberg agree that both parties have all rights, duties and remedies available as stated in the Uniform Commercial Code.
PART 1 – GENERAL
SUMMARY
This section specifies furnishing and installing a 300 Amp automatic transfer switch for the emergency power system.
REFERENCE STANDARD
The automatic transfer switch must be listed by Underwriters Laboratories in accordance with UL 1008 standards for emergency systems and rated for all classes of loads.
SUBMITTALS
Submit shop drawings. Include the following information as the minimum for review of the shop drawing:
MANUFACTURERS
Select the automatic transfer switch as produced by a qualified manufacturer regularly engaged in the design, development, and manufacture of electromagnetic switching devices. Acceptable manufacturers are Automatic Switch Company, Westinghouse, Russel Electric Co., Onan Corporation, or acceptable equivalent for the furnishing of automatic transfer switch as a part of the engine-generator set.
PART 2 – PRODUCTS
SWITCH DESCRIPTION
Type. The transfer switch shall be double throw, actuated by two electric operators momentarily energized, and connected to the transfer mechanism by a simple over center type linkage. Minimum transfer time shall be 400 milliseconds. The transfer switch shall be designed to have a pause position in either direction of operation.
Additionally, supply time delay adjustment in either direction of operation to allow pause position for motor load energy dissipation.
The normal and emergency contacts shall be positively interlocked mechanically and electrically to prevent simultaneous closing. Main contacts shall be mechanically locked in both the normal and emergency positions without the use of hooks, latches, magnets, or springs, and shall be silver-tungsten alloy. Separate arcing contacts with magnetic blowouts shall be provided on all transfer switches. Interlocked, molded case circuit breakers or contactors are not acceptable.
Locking Mechanism. The transfer switch must be mechanically locked in each direction without depending upon gravity, gear mechanisms, latches, or hooks. Use a switch designed so that release of the locking mechanism can be accomplished only by normal operation of the electrical operator.
The transfer switch shall be equipped with a safe external manual operator, arranged so that the transfer switch quick break - quick make mechanism can be operated manually under load without opening the enclosure door, designed to prevent injury to operating personnel. The manual operator shall provide the same contact to contact transfer speed as the electrical operator to prevent a flashover from switching the main contacts slowly. The external manual operator shall be safely operated from outside of the transfer switch enclosure while the enclosure door is closed. Internal manual operator is also acceptable
Operation. Provide inherently double throw operation actuated by electrical operators momentarily energized and connected to the transfer mechanism by a simple over center linkage. The switch design must prevent any possibility for both sides to be closed simultaneously. Use a switch in which an overload or short-circuit will not cause the switch to go to a neutral position.
Contact Protection. Protect main contacts by using arc barriers with separate arcing contacts on switches rated above 50 amperes. Provide blown construction, with rigid moveable contacts and deflection provided by the stationary contacts, on all switches rated 400 amperes and more. Make electrical spacings not less than those specified in Table 15.1 of UL Standard 1008.
Replacement of Parts. Provide a switch designed for inspection or replacement of stationary and moveable main contacts from the front of the switch without major disassembly of associated parts, without disconnection of the power conductors or main operator linkages, and without removal of the switch from the enclosure.
Identification. If main contacts consist of assemblies or subassemblies not originally manufactured for transfer switch service, fully identify each item by name of the original manufacturer, catalog number, and original electrical ratings. Describe any modifications made to the original products.
CONTROL FUNCTIONS
The controller software shall have the following adjustable settings programmed to the denoted values upon acceptance by City.
Adjustable time delays:
Undervoltage sensing: three-phase normal, three-phase emergency source:
Over-voltage sensing: three-phase normal, three-phase emergency source:
Over/under frequency sensing:
Voltage imbalance sensing:
The controller shall have password protection required to limit access to qualified and authorized personnel.
All reset and setup functions shall have a means for protection against unauthorized/accidental changes.
Phase rotation sensing:
Loss of single-phase detection:
GENERATOR EXERCISE & TESTING
An exerciser is specified to operate the engine-generator set. The exerciser schedule shall be adjustable by the City. Transfer switch wiring shall be designed to permit the starting of the engine-generator loaded or unloaded on a weekly basis.
A test switch to simulate a normal power failure shall be provided.
Pilot lights shall be provided on the cabinet door to indicate the switch position.
AUXILIARY CONTACTS
In addition to the auxiliary contacts required for engine-generator control provide two (2) sets of shaft mounted (position sensing) auxiliary contacts for normal and emergency switch positions (1 N.O. and 1 N.C. each position) for load control purposes.
ENCLOSURE
Mount the transfer switch in a NEMA 1 enclosure.
PRODUCT DATA
Place wiring diagrams and maintenance instructions on the inside of enclosure door in a mounting designed to hold the data.
PART 3 – EXECUTION
Install the transfer switch as shown on the drawings. Make the installation in accordance with manufacturer's instructions.
Restore any marred surfaces to factory finish.
Coordinate installation of A.T.S. with generator contractor. Provide assistance with installation of generator conductors and conduits. Contractor shall be present at final inspection and generator startup.
Test the switch with engine-generator plant in operation. Demonstrate to City’s representative that the automatic transfer switch performs all required functions.
