City of Everett 26 28 16 - 3 <br /> Inductive Charging Infrastructure for Everett Transit <br /> C. Electrical Components, Devices, and Accessories: Listed and labeled in accordance <br /> with NFPA 70, by qualified electrical testing laboratory recognized by authorities having <br /> jurisdiction, and marked for intended location and application. <br /> 2.2 FUSIBLE SWITCHES <br /> A. Not Required for this project. <br /> 1. [ <br /> 2.3 MOLDED-CASE CIRCUIT BREAKERS <br /> A. Circuit breakers must be constructed using glass-reinforced insulating material. Current <br /> carrying components must be completely isolated from handle and accessory mounting <br /> area. <br /> B. Circuit breakers must have toggle operating mechanism with common tripping of all <br /> poles, which provides quick-make, quick-break contact action. Circuit-breaker handle <br /> must be over center, be trip free, and reside in tripped position between on and off to <br /> provide local trip indication. Circuit-breaker escutcheon must be clearly marked on and <br /> off in addition to providing international I/O markings. Equip circuit breaker with push- <br /> to-trip button, located on face of circuit breaker to mechanically operate circuit-breaker <br /> tripping mechanism for maintenance and testing purposes. <br /> C. Maximum ampere rating and UL, IEC, or other certification standards with applicable <br /> voltage systems and corresponding interrupting ratings must be clearly marked on face <br /> of circuit breaker. Circuit breakers must be 100 percent rated. <br /> D. MCCBs must be equipped with device for locking in isolated position. <br /> E. Lugs must be suitable for 60 deg C rated wire on 125 A circuit breakers and below. <br /> F. Standard: Comply with UL 489 with required interrupting capacity for available fault <br /> currents. <br /> G. Thermal-Magnetic Circuit Breakers: Inverse time-current thermal element for low-level <br /> overloads and instantaneous magnetic trip element for short circuits. Adjustable <br /> magnetic trip setting for circuit-breaker frame sizes 250 A and larger. <br /> H. Adjustable, Instantaneous-Trip Circuit Breakers: Magnetic trip element with front- <br /> mounted, field-adjustable trip setting. <br /> I. Electronic Trip Circuit Breakers: Field-replaceable rating plug, RMS sensing, with the <br /> following field-adjustable settings: <br /> 1. Instantaneous trip. <br /> 2. Long- and short-time pickup levels. <br /> 3. Long- and short-time time adjustments. <br /> 4. Ground-fault pickup level, time delay, and I-squared t response. <br /> J. Current-Limiting Circuit Breakers: Frame sizes 400 A and smaller, and let-through <br /> ratings less than NEMA FU 1, RK-5. <br /> 26 28 16 - 3 ENCLOSED SWITCHES AND CIRCUIT BREAKERS <br />
