A small distribution panel that feeds your 12/24 V devices, each on its own fuse, from the busbar.
Every 12/24V device needs its own fuse sized to its wire. A DC fuse panel gives each circuit that protection in one tidy place, fed from the busbar.
It draws from the positive (or load) busbar and fans out to your individual DC circuits, each on its own correctly-sized fuse.
Design your van, boat, cabin or RV system in Wattonomy and it lists each DC circuit with its own fuse and wire gauge, fed from the busbar, in the build pack — from the appliances you actually run, sized to the recognized standard for your region. You see it on the wiring diagram, in the sized parts list, and in a plain-English build pack that explains the reasoning behind every choice. No account, no email — about a minute to a complete, validated design.
It splits one feed from the busbar into several protected 12/24V circuits, each with its own fuse sized to that circuit’s wire and load.
Each to protect its own conductor while carrying its load. Wattonomy sizes every branch from the circuit you enter.
It takes about a minute. No account, no email.
