I'm installing appliances in my 12v mobile solar system. Some of my appliances, like the ventilation fan, have a very small gauge wire on the appliance itself - 16 AWG. I'm running my circuites in 10 AWG. The fan draws 5Amp max.
If I use this calculator, it says that 10 AWG with 2% loss can be up to 24 feet. With 5% loss, it could be a 60 foot circuit. It also says that the 16 AWG can only be 6 feet at 2% loss, and 15 feet at 5% loss.
Question 1: Is it important to strive for the 2% here?
As for the fuse... it protects the wire ... which wire? do I do math on both wires, like:
14 feet of 10 AWG can carry 10 Amps, so I'd probably choose a 7.5 Amp fuse (can you use a fuse equal to the rating of the wire?)
6 feet of 16AWG can carry 10 Amps also, so I would likely choose the same 7.5 Amp fuse for that
Question 2: Does it work like that?
