At a much smaller 12V voltage (batteries, for example), the same 14 AWG wire can handle only 192 watts of electrical power. In the wattage charts below, we calculated wattages at 12V, 24V, 110V, 120V, 220V, and 240V for all wires.

Determine the Correct Wire Size (AWG) to Use Chart. Based off the Distance and amount of load (Watts) use the same or bigger size wire in the chart below for your project. The smaller the AWG the larger the wire size.
Convert American Wire Gauge (AWG) to diameter and area values in inches (in) millimeters (mm) or circular mil area (CMA) using the Wire Size Conversion Calculator.
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.
(For example: 2-1000W & 1-1500W, 240V heaters = 3500 Watts total. These 3 heaters would require 14/2 wire and a 20 Amp 2-Pole breaker if they were to all be placed on the same circuit. If more heaters are needed either run a new circuit or increase the wire and breaker size to accommodate the load.)
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).
