DONNELLY ENGINEERING ELECTRICAL <br /> j. Panelboard classification <br /> k. Submit coordination curves on log-log paper for all breakers, fuses, etc. <br /> I. If dimensions for equipment proposed in submitted shop drawings are different than what is <br /> shown on the drawings, the contractor shall submit sketches showing layout of proposed <br /> equipment. <br /> 1. Coordination Study: The Contractor shall expect an additional 10 working days for panelboard and <br /> switchboard review to allow the Engineer to design the coordination study. <br /> D. NFPA 70E compliance: The panelboards and switchboards shall have a NFPA 70E label applied to <br /> the front face. It shall include the PPE requirements and the hazard classification. Fault current levels <br /> are indicated in the plans. Note: A label indicating "NFPA 70E compliance" only is not acceptable. <br /> Coordinate with the engineer of record. <br /> 1.5 OVERCURRENT PROTECTIVE DEVICES <br /> A. Shop drawings and product data: Shop drawings shall clearly indicate; <br /> 1. Frame sizes and interrupting capacity of all circuit breakers. <br /> 2. Horsepower ratings of rated voltage of fused switches and circuit breakers. <br /> 3. Size and type of fuses being provided. <br /> 4. Device is listing by a nationally recognized testing Agency. <br /> 5. Device complies with these specifications, drawings, and applicable standards of NEMA, IEEE, and <br /> ANSI. <br /> PART 2— PRODUCTS <br /> 2.1 PANELBOARDS <br /> A. Equipment: The panelboard bus assembly shall be enclosed in a steel cabinet and shall be surface or flush <br /> mounted as shown in the schedules and drawings. The box shall be fabricated from galvanized steel with <br /> standard baked enamel finish. The panelboard front shall include a door-in-door design and shall have a <br /> flush, cylinder tumbler-type lock with catch and spring-loaded stainless steel door pull. Lift and shift cover will <br /> not be considered "door-in-door". All panelboard locks shall be keyed alike. All panel cabinets shall be a <br /> minimum of 20 inches wide. The panel fronts shall have adjustable indicating trim clamps which shall be <br /> completely concealed when the doors are closed. Doors shall be mounted with concealed steel hinges. <br /> Panel front shall not be removable with door in the locked position. <br /> B. Bus: Panelboard bus structures and main lugs or main circuit breakers shall have current ratings as shown <br /> on the panelboard schedule. The bus shall be insulated.The bus bar connections to the branch circuit <br /> breakers shall be of the "distributed phase" or phase sequence type. All current carrying parts of the bus <br /> structure shall be tin plated copper. A full size insulated neutral bus bar shall be provided. Provide system <br /> grounding tin plated copper bus bar bonded to the panelboard cabinet for connection of system grounding <br /> conductors. The bus bar shall be mechanically and electrically isolated from the neutral bar except where <br /> panelboard is used as service entrance equipment. <br /> C. Molded Case Circuit Breakers: All panelboard branch circuit breakers shall be bolt-on thermal-magnetic <br /> molded case type. Breakers shall be 1, 2 or 3 pole with an integral crossbar to assure simultaneous opening <br /> of all poles in multi-pole circuit breakers. Breakers shall have an over center, trip-free, toggle-type operating <br /> mechanism with quick-make, quick-break action and active handle indication. Handles shall have "ON", <br /> "OFF", and "TRIPPED" positions. Bolt-on circuit breakers shall be able to be installed in the panelboard <br /> without requiring additional mounting hardware. Multiple pole breakers shall not utilize individual single pole <br /> breakers with a common tie. <br /> Heartland Health Care Center of Zephyrhills, FL-3181 16470-2 DE No 217032 <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
