I have only one good spot to mount a switch/fuse panel and it's about 11'-13' from the battery. 1 bank for FF about 5'-6' (3amp?), 2nd bank for bilge about 15' away but close to battery so a short negative wire (1.5-2amp?), 3rd bank for nav lights eventually, and 4th bank a cigarette lighter accessory plug for cell phone and stuff. All will be connected to a 10 amp breaker at the battery so I am planning to keep it under 10amp total for the 4 bank. 12 awg should be plenty right? At 10amp my voltage loss is .0162v per foot. My max run is the FF which is about 30'-40' including pos and neg. At a full 10amps that's only .486v-.648v loss. I'll only have a 3 amp fuse on it so loss should be much less. At 5 amps I estimate .243v-.324v for 30'-40'. Am I on the right track??? Need some electrician opinions. Thanks!
