SesameCreeps Posted November 5, 2020 Report Posted November 5, 2020 Can you use a 100 amp fuse on a 1/0 wire? Wont it blow all the time? Reason being is the amplifier im about to use needs a 350 amp fuse. It comes with 2 sets of power and ground terminals. Manufacturer said 350 amps in TOTAL so if I wanted to use dual input adapters on each, than to use a 100 amp fuse on each wire. 4 power wires, 100 amp each. Am I missing something? How wouldnt a 1/0 ofc wire not burn up a 100 amp fuse?
Dafaseles Posted November 5, 2020 Report Posted November 5, 2020 Fuses can handle way over their rating for short bursts. Also, you're spreading the draw of the amp over 4 wires. The amplifier won't be pulling more than 350 amps, spread out over 4 cables. And if it does, it will only be for short bursts and the fuse shouldn't pop 2011 Chevy Silverado under construction My build log here. Check it out!
GoldRiver Posted November 6, 2020 Report Posted November 6, 2020 Current isnt just flowing through the wire. The amp draws current causing it to flow. Its the amp that determines how much current is demanded. A larger gauge wire just allows more current to flow safely. You size the fuse to the amp, not the wire size.
