If I only have 20 fuses in my cabin can I use 10 gauge wire in my AC outlet with my SPH8048P inverter

No, you should not use 10 gauge wire for the AC outlet with the SUNGOLD POWER SPH8048P inverter. The manual specifies a minimum cable size of 13 mm² (approximately 6 AWG) for AC output circuits. Using 10 AWG wire (which is smaller) may not safely handle the maximum output current and could pose a fire risk.
