In practice, we use wires from 16 AWG to as thick as 3/0 AWG for 12V circuits (size depends on the max. wattage and wire length or voltage drop). We have to be quite careful when sizing 12V wires. If we choose a wire with too low an ampacity, the circuit can go up in flames (as well as the battery).
What Happens If The Battery Cable Is Too Small? Thick wires have lower resistance, as we already explained. When current flows over a wire with resistance, two major things happen. Low Voltage. A voltage decrease is the first consequence. This indicates that there is a difference between the voltage at the battery and the voltage at …
