<br />ALTERNATE POWER SYSTEM.
<br />2.PV SYSTEM SCHEMATIC CONNECTIONS HAVE BEEN INCLUDED FOR REFERENCE ONLY. ACTUAL SYSTEM
<br />REQUIREMENTS SHALL BE DETERMINED BY EQUIPMENT / SYSTEM VENDOR AND INCORPORATED IN DEFERRED
<br />SUBMITTAL FOR PERMITTING.
<br />3.SPECIFIC REQUIREMENTS:
<br />3.1. THE SOLAR INTERCONNECTION TO THE BUILDING MAIN ELECTRICAL SERVICE SHALL BE IN ACCORDANCE
<br />TO CEC ARTICLE 690.
<br />3.2. THE PHOTOVOLTAIC SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH SECTIONS CEC 605.11.1-605.11.4.
<br />MARKING IS REQUIRED ON THE INTERIOR AND EXTERIOR DIRECT CURRENT ( DC ) CONDUIT, ENCLOSURES,
<br />RACEWAYS, CABLE ASSEMBLIES, JUNCTION BOXES, COMBINER BOXES, AND DISCONNECTS.
<br />3.3. SOLAR COMPONENTS SHALL BE LOCATED IN AREAS THAT DO NOT REQUIRE THE PLACEMENT OF GROUND
<br />LADDERS OVER OPENING SUCH AS WINDOWS, DOORS, AND MUST BE LOCATED OVER STROND POINTS
<br />WHERE ACCESS POINT DOES NOT CONFLICT WITH OVERHEAD OBSTACLES SUCH AS TREES, WIRES, OR
<br />SIGNS.
<br />3.4. THERE SHALL BE A SIX ( 6 ) FOOT WIDE CLEAR PERIMETER AROUND THE EDGES OF THE ROOF UNLESS
<br />EITHER AXIS OF THE BUILDING IS 250 FEET, THAN FOUR ( 4 ) FOOT CLEAR PERIMETER SHALL BE PERMITTED.
<br />SMOKE VENTILATION OPERATIONS REQUIRE DISTANCES BETWEEN ARRAYS TO BE EIGHT ( 8 ) FEET OR
<br />GREATER IN WIDTH OR A FOUR ( 4 ) FOOT, OR GREATER, PATHWAY AND BORDERING ROOF SKYLIGHTS, OR
<br />SMOKE AND HEAT VENTS OR A FOUR ( 4 ) FOOT, OR GREATER, AND A BORDERING FOUR ( 4 ) FOOT BY
<br />EIGHT ( 8 ) FOOT " VENTING CUTOUTS " EVERY 20 FEET ON ALTERING SIDES OF THE PATHWAY.
<br />3.5. THE ELECTRICAL INSTALLATION SHALL BE IN ACCORDANCE WITH THE CURRENT EDITION OF THE NATIONAL
<br />ELECTRICAL CODE ( NEC ) WITH CALIFORNIA STATE AMENDMENTS AS APPLICABLE AND SHALL BE
<br />PREPARED BY A LICENSED DESIGN PROFESSIONAL. IN ADDITION, THE GENERAL REQUIREMENTS OF
<br />CHAPTERS 1 - 4, SPECIAL REQUIREMENTS MAY ALSO APPLY. THE DESIGN SHALL COMPLY WITH ARTICLE
<br />690, 445, 480, AND 705. OTHER ARTICLES MAY ALSO APPLY DEPENDING ON THE SYSTEM CONFIGURATION.
<br />3.6. THE PHOTOVOLTAIC SYSTEM SHALL IN INSTALLED BY A QUALIFIED ELECTRICIAN.
<br />4. THE PHOTOVOLTAIC SYSTEM SHALL BE A DEFERRED APPROVAL. INSTALLATION OF THE PHOTOVOLTAIC
<br />SYSTEM SHALL NOT BEGIN UNTIL THE CONTRACTOR HAS OBTAINED A PERMIT FOR THE WORK BY THE
<br />AUTHORITY HAVING JURISDICTION.
<br />PV SYSTEM DEFERRED APPROVAL NOTES
<br />1.THE MAXIMUM AVAILABLE FAULT CURRENT IS BASED ON WORST CASE FAULT CURRENT PUBLISHED BY THE
<br />UTILITY COMPANY. CONTRACTOR TO OBTAIN FAULT CURRENT LETTER FROM UTILITY COMPANY FOR EACH
<br />SERVICE BEFORE ORDERING SWITCHBOARD. IF AVAILABLE FAULT CURRENT IS HIGHER THAN SHOWN IN
<br />THE DRAWINGS, CONTACT ELECTRICAL ENGINEER IMMEDIATELY.
<br />2.LETTER FOR SHORT CIRCUIT CURRENT VALUE FROM UTILITY COMPANY SHALL BE AVAILABLE AT THE JOB
<br />SITE FOR INSPECTION.
<br />3.ELECTRICAL EQUIPMENT SHALL BE LISTED BY THE CITY, WHERE THE PROJECT IS LOCATED, RECOGNIZED
<br />ELECTRICAL TESTING LABORATORY OR APPROVED BY THE DEPARTMENT.
<br />4.ALL NEW CIRCUIT BREAKERS, FUSIBLE SWITCHES AND ELECTRICAL EQUIPMENT SHALL BE FULLY RATED
<br />HAVING A SHORT-CIRCUIT (AIC) RATING EXCEEDING THE AVAILABLE SHORT-CIRCUIT CURRENT AT THE
<br />EQUIPMENT. SERIES RATING OF EQUIPMENT IS NOT ALLOWED.
<br />5.ALL SWITCHBOARDS AND DISTRIBUTION BOARDS SHALL HAVE:
<br />5.1.TIN-PLATED ALUMINUM BUSSING WITH RECTANGULAR CROSS SECTION. HORIZONTAL AND VERTICAL
<br />BUSSING SHALL BE FULL LENGTH AND SHALL HAVE PROVISIONS FOR FUTURE EXTENSIONS. ALL
<br />BUSSING SHALL HAVE MINIMUM WITHSTAND RATING EQUAL TO THE AVAILABLE FAULT CURRENT
<br />INDICATED. ALL VERTICAL AND HORIZONTAL BUSSING SHALL BE RATED AT FULL CAPACITY IN ALL
<br />SWITCHBOARD AND DISTRIBUTION BOARD SECTIONS. PROVIDE 100% NEUTRAL BUSSING MINIMUM
<br />UNLESS OTHERWISE NOTED. PROVIDE FULL LENGTH GROUND BUS AND, WHERE INDICATED ON PLANS,
<br />ISOLATED GROUND BUSSING. PROVIDE REAR WIRE WAY IN ALL SWITCHBOARD SECTIONS.
<br />5.2.LUGS SUITABLE FOR USE WITH COPPER OR ALUMINUM CONDUCTORS LISTED FOR USE WITH 75
<br />DEGREE CELSIUS AMPACITY CONDUCTORS.
<br />5.3.PERMANENT PLACARD(S) MARKED PER THE SPECIFICATIONS AND PER NEC (OR CEC-WHERE
<br />ADOPTED) SECTIONS 225.37, 230.2(E), 690.56, 692.56, 700.7, 701.7, 702.7, AND 705.10 DENOTING THE
<br />PRESENCE OF ADDITIONAL SERVICES, PHOTOVOLTAIC SYSTEMS, FUEL CELLS, EMERGENCY OR
<br />STAND-BY POWER SOURCES AS APPLICABLE.
<br />5.4.SINGLE LINE DIAGRAM SHOWN IS A "FULLY RATED SYSTEM" UNLESS NOTED. OTHERWISE.
<br />5.5.THE MAXIMUM COMBINED VOLTAGE DROP ON BOTH INSTALLED FEEDER CONDUCTORS AND BRANCH
<br />CONDUCTORS TO THE FARTHEST CONNECTED LOAD OR OUTLET SHALL NOT EXCEED 5 PERCENT.
<br />5.6.ALL ELECTRICAL EQUIPMENT SHALL BE LABELED, LISTED, OR CERTIFIED BY A NATIONALLY
<br />RECOGNIZED TESTING LABORATORY ACCREDITED BY THE "UNITED STATES OCCUPATIONAL SAFETY
<br />HEALTH ADMINISTRATION".
<br />GENERAL NOTES
