All SPDs shall be tested and demonstrate suitability for application within ANSI/IEEE C62.41 Category C, B, and A environments. B. Surge Current Capacity - The minimum surge current capacity the device is capable of withstanding shall be as shown in the following table: SURGE PROTECTIVE DEVICES 264313 - 5 DECEM BER 15, 2015 W EST AURORA SCHOOL DISTRICT #129 ADDITION, IMPROVEMENTS, & GEOTHERMAL INSTALLATION JEFFERSON MIDDLE SCHOOL PROJ.

All SPDs installed on the load side of the service entrance disconnect shall be Type 1 or Type 2 SPDs. LIGHTING AND DISTRIBUTION PANELBOARD REQUIREMENTS A. The SPD application covered under this section includes lighting and distribution panelboards. The SPD units shall be tested and demonstrate suitability for application within ANSI/IEEE C62.41 Category B environments. 1. 2. 3. 4. 5. 6. 7. B. Sidemount Mounting Applications Installation (SPD mounted external to electrical assembly) 1. C. The SPD shall not limit the use of through-feed lugs, sub-feed lugs, and sub-feed breaker options. SPDs shall be installed immediately following the load side of the main breaker. SPDs installed in main lug only panelboards shall be installed immediately following the incoming main lugs. The panelboard shall be capable of re-energizing upon removal of the SPD. The SPD shall be interfaced to the panelboard via a direct bus bar connection. Alternately, an SPD connected to a 30A circuit breaker for disconnecting purposes may be installed using short lengths of conductors as long as the conductors originate integrally to the SPD. The SPD shall be located directly adjacent to the 30A circuit breaker. The SPD shall be included and mounted within the panelboard by the manufacturer of the panelboard. The SPD shall be of the same manufacturer as the panelboard. The complete panelboard including the SPD shall be UL67 listed. Lead length between the breaker and suppressor shall be kept as short as possible to ensure optimum performance. Any excess conductor length shall be trimmed in order to minimize let-through voltage. The installer shall comply with the manufacturer's recommended installation and wiring practices. Switchgear, Switchboard, MCC and Busway Requirements 1. 2. 3. 4. 5. 6. The SPD application covered under this section is for switchgear, switchboard, MCC, and busway locations. Service entrance located SPDs shall be tested and demonstrate suitability for application within ANSI/IEEE C62.41 Category C environments. The SPD shall be of the same manufacturer as the switchgear, switchboard, MCC, and busway The SPD shall be factory installed inside the switchgear, switchboard, MCC, and/or bus plug at the assembly point by the original equipment manufacturer Locate the SPD on the load side of the main disconnect device, as close as possible to the phase conductors and the ground/neutral bar. The SPD shall be connected through a disconnect (30A circuit breaker). The disconnect shall be located in immediate proximity to the SPD. Connection shall be made via bus, conductors, or other connections originating in the SPD and shall be kept as short as possible. The SPD shall be integral to switchgear, switchboard, MCC, and/or bus plug as a factory standardized design.

NO. 15049 All monitoring and diagnostic features shall be visible from the front of the equipment. ENCLOSURES A. All enclosed equipment shall have NEM A 1 general purpose enclosures, unless otherwise noted. Provide enclosures suitable for locations as indicated on the drawings and as described below: 1. 2. 3. NEMA 1 - Constructed of a polymer (units integrated within electrical assemblies) or steel (sidemount units only), intended for indoor use to provide a degree of protection to personal access to hazardous parts and provide a degree of protection against the ingress of solid foreign objects (falling dirt). NEM A 4 - Constructed of steel intended for either indoor or outdoor use to provide a degree of protection against access to hazardous parts; to provide a degree of protection of the equipment inside the enclosure against ingress of solid foreign objects (dirt and windblown dust); to provide a degree of protection with respect to the harmful effects on the equipment due to the ingress of water (rain, sleet, snow, splashing water, and hose directed water); and that will be undamaged by the external formation of ice on the enclosure. (sidemount units only) NEM A 4X - Constructed of stainless steel providing the same level of protection as the NEM A 4 enclosure with the addition of corrosion protection. (sidemount units only) PART 3 - EXECUTION 3.1 INSTALLATION A. 3.2 The Contractor shall install all equipment per the manufacturer's recommendations and the contract drawings. FACTORY TESTING A. 3.3 Standard factory tests shall be performed on the equipment under this section. All tests shall be in accordance with the latest version of NEMA and UL standards. W ARRANTY A. The manufacturer shall provide a full ten (10) year warranty from the date of shipment against any SPD part failure when installed in compliance with manufacturer's written instructions and any applicable national or local code.
