Hello, I would like first to thank anyone taking the time to read this or help. I was wondering how to calculate how many amp I can use by connecting 2 different wire gauge. I am on a 12v dc circuit and would ie to connect a 12v led module to a battery for a long distance. The led modules come with a 22 awg gauge cable from the factory. I would like to run it for a long distance to the power source (battery or power supply) I plan to use awg 16 wire connected to the led module so I can make a big distance safely. I will solder the awg 16 to the awg 22 of the led module. I usually know how to calculate the max amp that I can run for a single wire gauge by looking at spec of wire. However I am not sure if the 22 awg wire gauge from the led will limit my 16 awg? Is the 16 awg maximum amp capacity is limited by the 22 awg or will the 16 awg be able to use it's full amp capacity?

So to calculate how far I can get with the awg 16 can I just calculate the 22 awg capacity and add to the 16 awg capacity or I need to calculate the 16 awg capacity as if it was a 22 awg?

I am sorry my english is not great I live in montreal and speak french

Thank again for any help

cheers
