ARRAY RACKING PLAN - PARTIAL ROOF PLAN

GENERAL NOTESA. CONDUCTORS FOR PHOTOVOLTAIC MODULES SHALL BE ROUTED IN

SUCH A MANNER THAT WILL CONCEAL THE CABLING AS MUCH ASPOSSIBLE FROM VIEW (I.E. SUPPORTED UNDER SOLAR MODULES).

B. ALL RUNS, WHETHER EXPOSED OR CONDUIT, SHALL BESYMMETRICAL, RECTILINEAR, AND ORDERLY. ALL WIRING SHALL BESECURED SUCH THAT IT IS NOT TOUCHING THE CANOPY ROOF,BUILDING ROOF, GROUND, STRUCTURE, OR ANY OTHER INCIDENTALSURFACE, OR HANGING IN SUCH A WAY THAT THE WIRING COULDEASILY MOVE WITH WIND FORCE. INSTALL EXPOSED CABLESPARALLEL AND PERPENDICULAR TO SURFACES OF EXPOSEDSTRUCTURAL MEMBERS, AND FOLLOW SURFACE CONTOURS WHEREPOSSIBLE.

C. ATTACH CABLING TO STRUCTURE UTILIZING MECHANICAL MEANSSUCH AS J-HOOKS, SNAKE TRAY, STAINLESS STEEL OR GALVANIZEDCLIPS, OR ZIP-TIES. WHEN USING ZIP-TIES, THEY SHALL MEET THEFOLLOWING CRITERIA: UV RESISTANT, 40 LB TENSILE STRENGTH,TEMPERATURE RANGE -20°F TO +165°F, OR BETTER, AND UL LISTED.BASIS OF DESIGN SHALL BE HELLERMANNTYTON PVDF SOLAR TIES,OR APPROVED EQUAL. IF USING ZIP-TIES, NO MORE THAN 6 CONDUCTORS SHALL BE BUNDLED IN EACH ZIP-TIE.

D. IN THE MODULE RACKING SYSTEM, INTER-ROW RUNS OF PV WIRESHALL BE SUPPORTED IN (PROPERLY SECURED) EMT, IMC, OR UVRATED RACEWAY, AND APPROVED BY THE MICROGRID ENERGYPROJECT MANAGER PRIOR TO INSTALL.

E. SECURE ALL MODULE WIRING WITHIN 12" OF ALL CONNECTORS, ANDEVERY 48" THEREAFTER.

F. ALL JUNCTION BOXES OR COMBINERS SHALL BE INSTALLED IN READILY ACCESSIBLE LOCATIONS. POSITION THE ROOF PENETRATION JUNCTION BOX OVER THE PENETRATION SUCH THAT ITDIVERTS RAINWATER AWAY FROM FALLING ON THE TOP OF THE PENETRATION. CONDUIT PENETRATIONS INTO ALL JUNCTION BOXESSHALL BE ON THE SIDES OR BOTTOM, AND NOT THE TOP SURFACE.

G. CONNECTIONS TO NEMA-3/3R (OR HIGHER) CONDUIT BODIES, WIREWAYS, AND JUNCTION BOXES SHALL BE MADE WITH UL-LISTEDWEATHER-TIGHT CONNECTORS TO MAINTAIN THE ENCLOSURE'SNEMA RATING.

H. WIRE GLAND OR CABLE GRIP SHALL BE UL-LISTED FOR NUMBER ANDSIZE OF CONDUCTORS TO PROVIDE STRAIN RELIEF FOR ALL CONDUCTORS PENETRATING A CONDUIT BODY.

I. OPEN-AIR RATED CONDUCTORS ENTERING CONDUIT BODES SHALL BEPROVIDED WITH DRIP LOOP THAT DIVERT WATER AWAY FROM WIREGLANDS.

J. CONDUITS SHALL BE INSTALLED SUCH THAT THERE IS NO GREATERTHAN FOUR (4) 90 DEGREE BENDS IN ANY SINGLE RUN. WHEREREQUIRED, INSTALL PULLBOXES SIZED PER NEC 314.28 & 314.70.

1. PROVIDE ARC FLASH WARNING SIGNAGE AS PER NEC 110.16.

2. AC DISCONNECT IS TO BE LOCATED WITHIN CLEAR VISUAL SITE OF THE INTERCONNECTION POINT AND AS IS PRACTICABLE TO THE UTILITY INTERCONNECTION

POINT.

3. INVERTER IS LISTED FOR UTILITY INTERCONNECTION AND HAS NO POTENTIAL TO ISLAND WHEN GRID FAILS. INVERTERS COMPLY WITH RAPID SHUTDOWN PER

NEC 690.12.

4. INSTALL ROOF-MOUNTED CONDUIT MINIMUM 3.5" ABOVE ROOF ON DURA BLOCKS OR EQUIVALENT.

5. INSTALLATION TO FOLLOW NEC AND STATE AND NATIONAL BUILDING CODE GUIDELINES.

6. EQUIPMENT GROUNDING CONDUCTORS ON AC AND DC SIDE ARE SIZED ACCORDING TO NEC 250.122.

7. ALL MODULES ARE CERTIFIED TO MEET UL 1703. ALL INVERTERS ARE CERTIFIED TO MEET UL 1741.

8. COMPONENTS IN HEAVY LINE TYPE ARE NEW AND ARE INCLUDED IN THIS SCOPE, INCLUDING INTERCONNECTION AT EXISTING 1000KVA TRANSFORMER.
