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.

Wire Size Chart. Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn't overheat.
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.
We can calculate how many watts can a 14 gauge handle (using electric power equation P = I×V) by knowing two things: Ampacity; we know that a 14 AWG wire can handle 20 amps. Voltage. This is 120V or 220V for most circuits; 12V and 24 for batteries. At 120V, a 14 gauge wire can handle 2,400 watts. At 220V, a 14 gauge wire can handle 4,400 watts.
17 mar 2010 · It is very common to use 14-gauge wire for light fixtures inside the home. Many recommend going up 18-gauge wire for LED lights. Your best option is to follow manufacturer recommendations for properly and safely connecting light fixtures.
