Yep...using the right/correct size fuses
Just my main power and ground to the aux fuse block is bigger than I need apparently...The runs coming off the fuse block are typically 10ga although those are probably overkill based on what I'm reading here
But it must work...CB, HAM, fridge, etc. all powered off the aux fuse block and no noise/problems so I'm happy
