Since your 50 amp shore power input is running thru this inverter, use 6 gage wire, as recommended.
While on 30 amp shore power, the hybrid inverter is designed to boost that amperage above that, up to 50 amps.
I was thinking of having 30 amp fuses but I guess it's silly I may as well just go with 6/3.
Next question not sure if you know. When I search for 6/3 wire this THN wire which is for submersible pumps comes up at a very good price. I was assuming I would use romex nm wire but if this is cheaper. Do you know if it would be appropriate?
