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 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).

What size wire for 12 volts? 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 ...
Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire.
2 Αυγ 2024 · Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire. The size of the wire dictates how much current can safely pass through the wire. Electrical current is measured in amps , and each wire gauge has a maximum safe carrying capacity.
This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps, voltage, distance, and load. This website provides a wire size calculator, voltage drop calculator, wire ampacity charts and more.
Due to its useful characteristics – we’ll cover 16 AWG to mm, 16 AWG to mm2, and 16 AWG amps and wattage – the 16 gauge electrical wire is widely used in home circuit boards, cars, and 12V batteries.
