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).

The appropriate wire size for a 12-volt system varies based on the current draw and wire length. Here are some general guidelines: For low current applications (up to 5 amps): 18-16 gauge wire; For medium current applications (5-20 amps): 14-10 gauge wire; For high current applications (20-50 amps): 8-4 gauge wire; For very high current ...
Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire.
The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

Knowing it can handle 17 amps we can calculate that the 16 gauge wire has the capacity to handle 2,040 watts (at 120V) and 3,740 watts (at 220V). Batteries have a 12V circuit. 16 gauge wire amps at 12V are the same; 17 amps. That means that a 16 gauge wire can handle 204 watts with a 12V battery.
2 Αυγ 2024 · You can determine the ampacity of wires you have on hand, and the gauge—or diameter—of wires needed for your project with a wire gauge chart. When purchasing wire, you'll see a few different numbers on the packaging or product description.
23 Μαΐ 2024 · Before considering a 16 gauge wire for home usage, let’s take a look at the maximum current a 16 gauge wire can handle at 12 volts. You may need to check this if you are working on smaller circuits or with an RV’s electric appliances.
