The Wiring Unlimited guide says that all DC consumers (load) need an individual fuse. I have about 10 DC consumers that I was planning on splitting into 3 groups and have an appropriate sized breaker for each of the 3 groups. Is this sufficient, or do I still need fuses on all 10 individual consumers? Also, is there any disadvantage to have the individual fuse right after the positive comes off the positive bus bar than directly before the load (consideration for changing blown fuses)?
