Conduit on the roof shall be installed no less <br />than 1" above the roof deck. PV Circuit conductor ampacity is constrained using the 75°C column with the <br />continuous duty uprating or the 90°C column with the relevant ambient temperature and raceway fill adjustments <br />without the continuous duty uprating per 690.8(B), whichever is the lower value will govern conductor sizing. <br />Non-PV Circuit Conductors use the ampacity in the 75°C column or the 90°C column with the relevant ambient <br />temperature and raceway fill adjustments, whichever is less (110.14(C) & 310.15(A)(2)). The rating of the <br />conductor after adjustments shall be greater than, or equal to, the continuous duty uprated current. <br />Calc Ex: Wire Ampacity x Ambient Temp. Corr.
