DONNELLY ENGINEERING ELECTRICAL <br /> D. Solid State Circuit Breakers: Provide solid state circuit breakers for all breakers 600 amperes and above. <br /> Breakers shall have adjustable settings for long time, short-time, instantaneous, long time delay and short <br /> time delay. <br /> E. 120/208 Rating: 120/208 volt circuit breakers shall have interrupting ratings a minimum of 10,000 rms <br /> symmetrical amperes at 240 volts AC maximum. <br /> F. Switching Type: Single pole, 15 and 20 ampere circuit breakers intended to switch fluorescent lighting loads <br /> on a regular basis shall carry the SWD marking. <br /> G. Directories: A typed panelboard directory shall be provided for each panelboard and shall indicate the actual <br /> circuit number used, room name and type of load. Room names shall be the actual name and room number <br /> used not necessarily as shown on the drawing. Panel directories shall include all room numbers and names. <br /> Where panel schedules are indicated on the drawings as "receptacles or "lighting", etc., it shall be the <br /> responsibility of the Contractor to include the specific area served. <br /> H. Bracing: The panelboard, as a complete unit, shall be braced for a minimum short circuit rating equal to or <br /> greater than the lowest breaker symmetrical interrupting capacity as shown on the schedule. All panelboards <br /> shall be fully rated. No series ratings are allowed. <br /> I. Grounding: All panelboard cabinets shall have a system grounding bar bonded to the panelboard cabinet for <br /> connection of system grounding conductors. This bar shall be mechanically and electrically isolated from the <br /> neutral bar. <br /> J. Stubs: Provide four 3/4 inch conduits from all flush mounted panels to adjacent accessible ceiling space and <br /> mark"for future use". Provide pull cord in all empty conduits and provide plastic end bushing. Provide conduit <br /> opening tape to seal. <br /> K. Design Selection: Square "D" NQOD for panelboards. Square "D" I-Line for 800 and 1200 amp distribution <br /> panels. Acceptable manufacturers are EATON and GENERAL ELECTRIC. The manufacturer shall submit a <br /> coordination study with the shop drawings. <br /> PART 3 -EXECUTION <br /> 3.1 INSPECTION <br /> A. General: Examine area to receive panelboard and assure that there is adequate clearances to meet NEC <br /> requirements and normal maintenance issues. <br /> B. Correction: Start work only after any unsatisfactory conditions have been corrected. <br /> 3.2 INSTALLATION <br /> A. General: Provide panelboards in complete accordance with manufacturer's written instructions and all <br /> applicable codes. <br /> B. Support: Panelboards shall be rigidly supported and installed per manufacturers recommended supporting <br /> instructions, with beams provided if necessary, to suit actual site conditions. Panels shall not be directly <br /> mounted to masonry walls. Use kindorf or similar channel for surface mounted locations. <br /> C. Storage and Delivery: Panelboards shall be delivered to the site during that phase of panelboard installation <br /> in order to avoid storing panels on site where damage may occur. Replace any damaged parts prior to <br /> energizing panel. Cover panelboard to avoid damage to finish. <br /> D. Mounting: Do not mount equipment directly to masonry or concrete walls. Provide two uni-strut spacers <br /> between wall and panelboard. <br /> i <br /> Heartland Health Care Center of Zephyrhills, FL-3181 16470-3 DE No 217032 <br /> 38220 Henry Drive,Zephyrhills, FL 33542 Pending Emergency Rule 59A-4.1265 <br />
