Cosa tratta questo video
Fuses and circuit breakers must be installed on the battery side of every positive wire to protect against short circuits and overcurrent events.0:26 Placing protection as close to the battery as possible ensures that if a wire shorts to ground, the fuse blows before the wire can melt.3:42 This rule applies to all loads and chargers, as batteries can discharge massive amounts of current during a fault.1:55 In complex systems using a Victron Lynx distributor, Blue Sea Safety Hub, or Tiger Expedition UFO 200, the distribution block acts as the central hub, but individual wires must still be fused at their source.0:46 While short battery-to-battery interconnects are often exempt from fusing due to their length and low risk of abrasion, all other positive conductors require protection.5:30 For shore power, the pedestal breaker provides necessary protection, though the ABYC recommends an additional breaker within 10 feet of a boat's shore power inlet.7:19 Proper placement prevents fire hazards by isolating faults at the power source.3:42
