4.5.1 Wiring Gauge
The required gauge of the AC input, DC+/DC- input and AC output cabling is determined by the current rat-
ing, circuit breaker rating, typical ambient temperatures and the applicable local electrical codes. Typically
the AC input and standard AC output is five wires (L1, L2, and L3, N, G) up to 350 kcmil THHW or RW90 type
cable that connects to the HP system with trade size up to 2.5" conduit.
