GENERAL NOTES:
1.ELECTRICAL
1.1.ALL WIRING MUST BE PROPERLY SUPPORTED BY DEVICES OR MECHANICAL MEANS DESIGNED AND LISTED FOR
SUCH USE. FOR ROOF-MOUNTED SYSTEMS, WIRING MUST BE PERMANENTLY AND COMPLETELY HELD OFF OF
THE ROOF SURFACE.
1.2.SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH ALL RELEVANT CODE.
1.3.RAPID SHUTDOWN INITIATION TAKES PLACE WITHIN THE FIRMWARE OF THE INVERTER. RAPID SHUTDOWN
COMMENCES UPON LOSS OF UTILITY SOURCE VOLTAGE.
1.4.SEE *PV EE 1.0 FOR DIAGRAMS, CALCULATIONS, SCHEDULE AND SPECIFICATIONS.
2.STRUCTURAL
2.1.THE SOLAR PANELS ARE TO BE MOUNTED TO THE ROOF FRAMING USING THE ULTRARAIL SYSTEM BY
SNAPNRACK. THE MOUNTING FEET ARE TO BE SPACED AS SHOWN IN THE DETAILS, AND SHOULD BE
STAGGERED, WHERE POSSIBLE, TO ADJACENT FRAMING MEMBERS TO SPREAD OUT THE ADDITIONAL LOAD.
2.2.UNLESS NOTED OTHERWISE, MOUNTING ANCHORS SHALL BE 5/16" LAG SCREWS WITH A MINIMUM OF 2 1/2"
PENETRATION INTO ROOF FRAMING.
2.3.THE PROPOSED PV SYSTEM ADDS 3.0 psf TO THE ROOF FRAMING SYSTEM.
2.4.ROOF LIVE LOAD = 20 psf TYPICAL, 0 psf UNDER NEW PV SYSTEM.
2.5.GROUND SNOW LOAD = 0 psf

Conductor Calculations
Wire ampacity calculated from 310.15(B)(16) & (17) as appropriate with ambient temperature
calculations from 310.15(B)(2)(a) & 310.15(B)(3)(c) and raceway fill adjustments from 310.15(B)
(3)(a). Conduit on the roof shall be installed no less than 1” above the roof deck.
PV Circuit conductor ampacity is constrained using the 75°C column with the continuous duty
uprating or the 90°C column with the relevant ambient temperature and raceway fill adjustments
without the continuous duty uprating per 690.8(B), whichever results with a larger wire size.
Non-PV Circuit conductors use the ampacity in the 75°C column or the 90°C column with the
relevant ambient temperature and raceway fill adjustments, whichever is less (110.14(C) &
310.15(A)(2)). The rating of the conductor after adjustments shall be greater than, or equal to,
the continuous duty uprated current.
More information about conductor calculations can be provided upon request.
Calc. Ex: Wire Ampacity x Ambient Temp. Corr. Factor x Conduit Fill Adj. Factor >= Output Current
