Fuses must be rated at the same or less rating of the wire. As an example ill use my 12 light bar.

It is also dictated by the max current rating of the thinest wire. A 4 led array draws 0.035 amps if small leds are used. 0.125 amps if they are power leds.

#### This Should Be Sized At 1.5 Times The Maximum Load Of The System.

For the trolling motor use a 50 amp circuit breaker. What is the general rule of thumb for sizing the correct size of fuse?? All the fuses that came with the switch panel are 10a. but i would have thought that some things require less. my gps says 1a. and the echo sounder only 0.25a.
