I'm in the middle of adding an optima battery. The stock battery has been moved into the storage compartment and they are linked together via a PAC200 isolator. I had planned to just run some power cable from the optima to a Blue Sea fuse block that I have mounted under the dash and then power my accesories from there. But after reading the Blue Sea fuse block box, it states that "Suitable main circuit protection of not more than 125A rating should be provided ahead of this device with and interrupt rating consistant with the battery capacity". So does this mean I need to put a circuit breaker or high amp fuse between the optima and fuse block? What are you guys using to do this? or are you guys even doing this at all?
