Inverter Wiring - are 2 25 amp inputs the same as 1 50 amp?
Each circuit in the fuse box wired to the house battery of my e350 diesel has a max load of 30 amps and I want to wire in an inverter thatís supposed to be protected with a 50 amp fuse. I donít want to run any more wire directly to the house battery. Option one would be to run a line with a 50 amp inline fuse from the hot terminal on the fuse box to the inverter. Option two, which is my preferred option, is to run two 25 amp circuits to the inverter. Iíd run one set of a hot and a ground from the fuse box to the inverter with a 25 amp fuse and then run a second hot and cold from the fuse box to the inverter, also with a 25 amp fuse. Would this work? Are two 25 amp lines equivalent to one 50 amp line? It seems to me that the worst case scenario would be one or both fuses would blow.
