Selecting the correct DC fuse for a DIY camper electrical system requires evaluating three primary specifications: maximum voltage, amperage range, and Ampere Interrupt Capacity (AIC).1:00 AIC represents the maximum current a fuse can safely interrupt during a short circuit; if the fault current exceeds this rating, the fuse may weld shut and fail to cut power.1:29
Common fuse types include glass (AGC) fuses, typically found in pre-built equipment like Victron monitors, and standard blade fuses used for small DC branch circuits.2:50 Maxi fuses offer higher amperage for OEM applications, while midi fuses are common for DC-to-DC charger connections.3:24 For main system protection, Marine Rated Battery Fuses (MRBF) provide a high 10,000 AIC rating, making them suitable for lithium battery banks.5:33 Mega fuses are standard for connections within a Victron Lynx distributor, though their 2,000 AIC rating limits their use near battery terminals.6:15 ANL fuses serve as the current standard for main system protection, while Class T fuses offer the highest safety with a 20,000 AIC rating, despite recent supply chain shortages.6:53
