But if you put a five amp fuse on one leg, the fuse will not blow because the increased resistance of the heated up fuse will send the current down the other leg. The same holds true for a one amp fuse. All magically done with no user intervention.
I wasn't aware of that, but I'm sure my dual relay setup is operating as you indicate. When the original relay failed a few years I doubled up, installing them in parallel, and I've had zero issues since.
