Wiring for 25 amps? what's the safest size
I have 7 55watt (home made) panels ... I'm wiring them all into a combiner box i made, each panel is about 3 to 3.5 amps a piece, so I'm coming out of the combiner box around 20 to 25 amps, I have about 80 feet of 14 gauge Romex wire i got for free, the distance between array and charge controller is about 15-20 feet.. Can i use 14 gauge wire to run 25 amps from combiner box to charge controller without burning the wire? The fuses I'm using are 5 amps they are on the positive leads of each panel coming into the postive bus bar in the combiner box.
