H. Statement of manufacturer’s warranty duration and replacement policy.

PART 6 – REQUIREMENTS 6.1 The Surge Protective Devices (SPDs) shall be of a parallel-connected design using fast-

acting transient energy protection components that will divert and dissipate the surge energy.

6.2 All SPDs shall be tested and listed to ANSI/UL 1449-2006 (UL 1449 3rd Edition) &

Complimentary Listed to UL 1283 by a Nationally Recognized Testing Laboratory (NRTL) (i.e. CSA, UL, etc).

6.3 SPDs shall be Type 1 or Type 2 SPDs, as application dictates; Type 4 SPDs are not

permitted. 6.4 The SPD shall be tested and listed by an NRTL as a complete assembly to a

symmetrical fault current rating greater than or equal to the available fault current at the location of installation at the connected panel, in accordance with NEC Article 285 and shall be marked with the Short Circuit Current Rating (SCCR). If the available fault current is unknown, then the SCCR of the SPD shall be 200 kAIC.

6.5 Permanently connected devices mounted parallel to the service, distribution, and sub

panels are required. SPD device drawings shall be made available upon request. 6.6 The SPD shall have a Nominal Discharge Current (In) of 10 kA. ((The Nominal

Discharge Current Test was designed to establish that the SPD remains functional after




15 surges at various currents (3 kA, 5 kA, 10 kA, and 20 kA) using the test procedure described in ANSI/UL 1449-2006.))

6.7 FUSING:

A. The SPD shall provide as a minimum, over-current, over temperature protectionin the form of component-level thermal fusing to ensure safe failure and preventthermal runaway. This component-level fusing shall be an integral part of theMOV itself and not silver wire (or other) independently laid across each MOV.SPDs without thermal fuses or disconnects, or SPDs with shared thermaldevices that disconnect more than one MOV are not acceptable.

B. Surge protective devices shall contain integral short circuit current safety fusingwithin each device for over-current requirements of the NEC. This fusing willbe independent of the “component-level” fusing and be specifically for over-current protection and shall be constructed utilizing surge rated, cartridge fusesand not rated ‘silver-fuse-wire’ (or other).

C. The use of any mechanical or electro-mechanical thermal/over-currentprotection (i.e. moving parts and/or springs and shutters) in combination with orfor the protection of the suppression elements is expressly prohibited and willbe rejected.

D. The fusing mechanisms employed must effectively coordinate theirperformance in conjunction with the high current abnormal over-voltage testingunder ANSI/UL 1449-2006 (a.k.a. UL 1449 3rd Edition).

6.8 MCOV:

The SPD shall have a maximum continuous operating voltage (MCOV) capable of sustaining 115% of nominal RMS voltage continuously without degrading.

6.9 COMPONENT LIMITATIONS: The SPD shall only use solid-state clamping components to limit the surge voltage and divert the surge current. SPD components that “crowbar” short-circuit the AC power system (e.g. spark gaps, gas tubes, selenium cells, or SCR’s) shall not be acceptable. Device circuitry shall be bi-directional, enclosed in a UL listed encapsulated thermal stress reducing compound, and be of a parallel design.

6.10 PROTECTION MODES: The SPD system shall provide (per IEEE Std. 1100-1999 8.6.1) dedicated, independent, distinct, individual protection circuitry for every possible mode in the electrical distribution system at the point of SPD application. For example, a 277/480V, 3-phase Wye, 4-wire plus ground system has 10 distinct modes that require independent and dedicated protection (i.e., L1-L2, L2-L3, L3-L1, L1-N, L2-N, L3-N, L1-G, L2-G, L3-G, N-G). None of these modes of protection depend on protection elements purposed for other protection modes. Reduced mode

SPD with only 3, 4, or 7 dedicated, distinct, independent protection modes are not acceptable and are not to be submitted. For 6 mode delta systems, 6 dedicated, independent, distinct protection modes are required (L1-L2, L2-L3, L3-L1, L1-G, L2-G, L3-G). When a mode of




protection is specified, the protective mode must be specifically included. Thus, Line-to-Neutral-to-Line is not acceptable where Line-to-Line is specified. 6.11 SINEWAVE TRACKING CAPABILITY: Power panels and MCCs serving sensitive electronic equipment shall utilize voltage independent, dedicated Sinewave Tracking circuitry. EMI/RFI filtering specifically will not be considered as equal to sinewave tracking! To demonstrate the sinewave tracking capability of the submitted devices, manufacturers shall submit 3rd party, independent tests results for units claiming sinewave tracking capability. Such tests shall include testing under the standards of ANSI/IEEE C62.41 and C62.45 category A1 (2kV, 67A, 100kHz ring wave) applied at the 270 degree phase angle, positive polarity, on a 120/208Vrms, 3 phase Wye device, on each of the following modes: line-to-neutral, line-to-ground, and line-to-line (dynamic tests with normal voltage applied to the unit under test), and neutral-to-ground (static test with no normal voltage applied to unit under test). The “let-through voltage” derived from each of these tests shall have a maximum amplitude of less than 50V peak deviation from the insertion point of the surge on the sine wave to the peak of the transient. Measurement of the let-through voltage shall be made with six-inches of lead length external to the SPD housing in accordance with ANSI/UL 1449-2006. Performance requirements are as stated in the table in Section VIII below (ANSI/IEEE C62.41 Let-Through Voltage) at Test Category A1. 6.12 STATUS INDICATORS: SPD UNITS SHALL HAVE PANEL FRONT STATUS MONITORS AS A MINIMUM TO INDICATE A CONTINUOUS POSITIVE STATUS OF EACH PROTECTED PHASE. A REMOTE AUDIBLE ALARM OPTION MUST BE SUPPLIED WHERE THE SPECIFYING ENGINEER DEEMS IT NECESSARY AND COST EFFECTIVE UNDER THE CIRCUMSTANCES. REFER TO THE APPROPRIATE DRAWINGS AND SCHEDULES FOR THESE DETAILS. 6.13 EQUIPMENT CERTIFICATION: Items shall be listed to ANSI/UL 1449-2006, shall bear the seal of the NRTL, shall bear the Marking “Listed to UL 1449”, shall have been tested under ANSI/UL 1449-2006, and shall be marked in accordance with the referenced standard. SPD units shall be UL 1283 Listed as an Electromagnetic Interference Filter and marked accordingly. All surge suppression devices shall be manufactured by an ISO 9001-2001 certified company normally engaged in the design, development, and manufacture of such equipment. 6.14 CIRCUIT CONFIGURATION: The circuit configuration of the suppression units shall be bi-directional, thermal stress reducing, encapsulated, custom parallel connected, and solid state. (Series units or units equipped with “load carrying” components are expressly prohibited due to the possibility of single point series failures causing power interruption to protected loads.) 6.15 ENCLOSURES: Unless otherwise noted, provide NEMA 1 or better enclosure for indoor mounting and NEMA 4 enclosure or better for all outdoor locations. All units will contain Form C, N/O or N/C, dry relay contacts, if so specified, and weatherproof fittings to maintain the required NEMA integrity. 6.16 MAINTENANCE RESTRICTIONS:




No suppression unit shall be supplied which requires scheduled preventive maintenance or replacement parts. Units requiring functional testing, special test equipment, or special training to monitor surge protection device (SPD) status are not acceptable. SPD shall require NO routine maintenance. SPD devices are considered non-repairable items and shall be fully replaced upon failure. 6.17 COMMONALITY: All SPDs at the service entrance, distribution panels, and sub-panels shall be from the same manufacturer. 6.18 All SPDs shall meet or exceed the following performance criteria:

A. Service Entrance (Category C): Service Entrance (Category C): The SPD shall provide a minimum protection of 480 kA or 240 kA per phase – (REFER TO CONTRACT DRAWINGS FOR SPECIFIC RATING), (three-phase Wye) and be capable of meeting the Category C-High Let-Through Voltage criteria as shown in the Section VII, below.

All voltages shall be peak (±10%) Positive Polarity, Time base = 10μS, Sampling Rate = 500 Megasamples per second to ensure maximum transient capture. [These settings assure Let-through Voltage test results are accurate]. Surge voltages shall be measured from the insertion of the surge on the sine wave to the peak of the surge. All tests are Static (unpowered), except for the 120V circuits that are Dynamic (powered). Let-through voltages on static tests calculated by subtracting sine wave peak from let-through measured from zero. All tests shall be performed in accordance with UL 1449 Third Edition with measurements performed at a point on the leads 15.24 cm (6 inches) outside of the device enclosure.

Warranty will provide for multiple exchanges of any inoperable devices at any time during the warranty period that starts at the date of substantial completion of the system to which the surge suppressor is installed.

9.3 SPD manufacturers whose warranty does not meet the requirements listed above standard

shall submit a letter extending the warranty to meet these standards with the product submittal

PART 10 - INSTALLATION 10.1 Provide surge suppressor at each building service entrance and at other distribution and

panelboard locations as indicated on the drawings. The SPD shall be located immediately adjacent to the switchboard or panelboard being protected (close-nipple to panel-boards). The SPD may be located integral (switchgear manufacturer installed)




within a switchboard if the switchgear manufacturer providing such SPD products expressly meets or exceeds ALL parameters of this specification for the SPD. These SPDs shall be individually tested and Listed to ANSI/UL 1449-2006 according to their type and not be listed solely as part of the larger assembly. SPD devices not meeting or exceeding the performance of this specification will be deemed unacceptable.

10.2 Do not energize or connect service entrance equipment and panelboards to their sources until TVSS devices are properly installed and connected.

10.3 Do not perform insulation resistance tests of the distribution wiring equipment with the TVSS installed. Disconnect before conducting insulation resistance tests, and reconnect immediately after the testing is over.

10.4 Install the SPD with #10 AWG minimum conductors to dedicated 30-amp breaker(s) in panel per manufacturer’s installation instructions and close to the Neutral Bus. The dedicated breaker shall serve as a means of service disconnect for the SPD so that the electrical panel remains energized during SPD servicing. The installer may rearrange breaker locations to ensure the shortest and straightest leads to the SPD. If a dedicated breaker is not provided, an SPD with internal 30-amp fuse or a UL Listed fused disconnect switch shall be installed as a minimum. The conductors serving the SPD shall be twisted together (one twist per 12” of wire) to reduce the SPD system input impedance and shall be kept at the minimum length. The SPD shall be installed in strict accordance with the manufacturer’s recommended practices and in compliance with N.E.C. requirements, State, and Local Codes.

REVISED by Addendum No. 1 09339 31 23 18 Unclassified Excavation

2017.06.06 Page 1 of 3

UNCLASSIFIED EXCAVATION

1. SCOPE OF WORK Work under this item shallconsist of the excavation of all materials encountered within the limits of the work and thedisposal of excavated materials by hauling to embankment or waste. Excavation shall becarried to the section and grade shown on the plans. Excavation for storm sewers anddrainage structures is covered elsewhere.

2. GENERAL The area shall be clearedand grubbed prior to the start of excavation. The Contractor shall inform himself as to theproper movements of haul and disposal of materials.

All suitable materials excavated shall be used in the formation of embankments and backfill as directed. During the process of excavation, the grade shall be maintained in such condition that it will be well drained at all times, and temporary ditches shall be cut to divert surface water which may affect the prosecution of the work. Prior to acceptance, then entire area shall be machined and bladed for proper drainage.

The rough excavation shall be carried to such depth that sufficient material will be left above the designated subgrade to allow for compaction of this grade. Likewise, on embankments, sufficient material shall be placed above the designated subgrade to allow for both compaction and settlement. Should the Contractor, through negligence, excavate below the designated line, he shall replace at his own expense such excavation with approved materials.

3. DISPOSAL OF UNSUITABLE ANDSURPLUS MATERIALS Any material encountered

which, in the opinion of the Engineers, is unsuitable for use in the work, shall be removed and disposed of as directed. No excavation shall be wasted without permission of the Engineers. Surplus excavation shall be disposed of as directed - some in uniformity widening embankments or flattening slopes. Waste excavation shall be left presenting a neat appearance well drained and smoothed suitable for mowing. Excavation material in excess of on-the-site requirements shall be hauled and deposited at a site provided by the Contractor unless a site si designated on the plans. Spoils from ditch excavation shall be spread and leveled to blend with the well-drained, pleasing appearance.

4. EMBANKMENTS Embankments shall be formed of satisfactory materials placed in successive horizontal layers of not more than 12 inches in loose depth for the full width of the cross-section. The Contractor shall route his equipment at all times over the layers so as to distribute evenly the travel over the entire width.

5. BORROW EXCAVATIONSAND CLAY TOPPING The borrow excavation and

sand clay topping materials shall be a mixture of clay and mineral aggregate. This mixture

174


2017.06.06 Page 2 of 3

shall consist of topsoil, sand-clay gravel, disintegrated granite, or other approved selected aggregate, and it shall contain sufficient binder material so blended or processed as to produce a uniform mixture complying with the requirements of these specifications.

The materials shall be uniform and free of organic matter such as leaves, grass, roots and other objectionable or foreign substances.

The gradation of the blended or processed material shall meet the requirements of the Select Borrow Material section contained within the Granular Materials specification.

6. SUBGRADE PREPARATION FOR BASE COURSE After all storm sewers, drainage structures and curbs and gutters have been completed, backfilled and compacted, the top portion of the subgrade, both cut and fill sections, shall be shaped correctly and brought to a firm, unyielding layer. The top 6 inches under the base course shall be compacted to a least 95% Standard Proctor Method density at optimum moisture content.

Rolling and compaction of the entire area shall done with equipment which will attain maximum results. Sheepsfoot, rubber-tired, or flat rollers shall be used as, in the opinion of the Engineers, conditions require. Any portion of the area which is not accessible to a roller shall be compacted to the required density by other approved means.

Any irregularities or depressions that develop under rolling shall be corrected by loosening the material at those places and adding, removing, or replacing material until the surface is smooth and uniform. All soft and yielding material which will not compact readily when rolled or tamped shall be removed as directed by the Engineers and replaced with suitable material.

During all compacting operations, the water content of the material shall be constantly adjusted, if necessary, by sprinkling or loosening and subsequent evaporation to within 2% by weight of the optimum moisture content.

At all times the top of the subgrade shall be kept in such condition that it will drain readily and effectively. The Contractor shall protect the subgrade from damage, and in no case will vehicles be allowed to travel in a single track. If ruts are formed, the subgrade shall be reshaped and rolled.

The top of the subgrade shall be of such smoothness that when tested with the parabolic roadway template, it shall not show any deviation in excess of ½-inch nor shall it be more than 0.05 foot from the true established grade.

Where material is encountered that will not permit satisfactory compaction for subgrade, excavation, disposal and replacement of this material will be required and will be considered as incidental to subgrade preparation. No extra pay will be allowed for this item.

7. HAUL All materials shall behauled from the original position to embankment or waste to the final position as directed.All haul shall be “free haul”, and no payment will be made therefor.

8. METHOD OF MEASUREMENT When, in the opinionof the Engineers, the unclassified excavation is completed in accordance with the plans,the quantities shown on the plans will be considered the measurement for final payment.If it is found necessary during construction, in the opinion of the Engineers, to makeconstruction changes, the original plans will be revised to incorporate such changes andthe change will be measured to neat lines of the change.

9. BASIS OF PAYMENT UnclassifiedExcavation, when not a Lump Sum pay Item, will be paid for at the contract unit price percubic yard for unclassified excavation; plan measure, which price shall be fullcompensation for the removal and satisfactory disposal of all excavated materialsregardless of material encountered; for haul to embankment areas; for the formation ofembankments; for compaction; and for subgrade preparation under areas to be coveredwith the base course.

Borrow Excavation and Sand Clay Topping will be paid for at the contract unit price per cubic yard, plan measure - which payment will be full compensation for locating, acquiring, and furnishing the material, haul and the formation of embankments. The yardage to be paid for shall be the number of cubic yards hauled to the job site as directed by the Engineer in the presence of the Engineer’s Representative. Any material hauled to the job site without notifying the Engineer will not be paid for. The quantity includes a 50 percent shrinkage factor.

No compensation shall be made for the haul to embankments or for the formation of embankments. Embankments are considered a necessary part of the roadway and incidental to the Unclassified Excavation item.
