The chart below shows the appropriate wire size (AWG) to use based off the amount of load (watts) that wire is carrying over a given distance. All distances calculated below keep within an 8% voltage drop limit*.
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. This chart assumes you are using Copper Wires, have 24V DC at the power source ...
Add up the total wattage of all the lights you plan to connect to the wire. Measure the distance of your wire run from your transformer to the last light. Use the chart to determine what size wire each wire run on your job requires.
14 kwi 2023 · A step-by-step guide for determining the correct wire gauge Check and calculate the length of wire required for connection, such as the LED light bar. Once that's done, find the current the wire can handle.
Use the following calculator to determine if the wire gauge is sufficient for your LED strip wires. The calculator also provides an estimated voltage drop across the wires. Keep in mind the results do not include the voltage drop of the LED strip itself and only includes the voltage drop in the wires.
Say you have a 12v strip with 300 white LEDs per meter, and the LEDs are rated for 50 mA each. White LEDs need approx. 3.2v to light which means you can only put 3 in series and still feed them 12v. Most 12v strips are cuttable every 3 LEDs because of this.
