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 is the lower value will govern conductor sizing. 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. Calc Ex: Wire Ampacity x Ambient Temp. Corr. Factor x Conduit Fill Adj.
