Figuring Proper Fuse Size
Hi folks, looking to install solar and an inverter on a new trailer and am looking for someone review my fuse needs, here's the scenario. dual 6V batteries, 230A. 1500w Inverter, 125A Solar Contr...

In a 300W inverter, the max it draws is 30 amps from the batteries (maybe it can draw up to its surge rating IDK). If I have wiring that can accommodate 100-380 amps (this is my setup), how is a short going to do anything to the wire? If the equipment shorts internally, it has fuses and protection circuits to handle that. Not to mention, shorts ALWAYS lead to an open and usually in a short period (pun) of time because internal circuitry is not designed to run over its design parameters. I'd be more worried about the equipment catching fire than wiring melting.
Fuses protect the equipment and the wiring. Wiring can develop a short and you certainly want a fuse to protect it and the equipment.
