What on earth is DC circuit one? It randomly died today I'm plugged into a house dropping from 30 to 20 but its been fine for 5 days. I put another one in it and it immediately blows on contact. I can't seem to locate what it does. Does it have to be that brand of 15 amp fuse or should auto store one will be okay. I know i shouldn't but would putting a 20 amp in there be okay?
