WebI (Amps) = P (Watts) / 12V With this formula, we can calculate how many amps are likely to run in the 12V circuit. Example: If we want to run a 150W device, we will need I = 150W / 12V = 12.5 Amps. On top of the calculated amps, we have to apply the 80% National Electric Code (NEC) rule. WebThe 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 …
