I currently use a regular 50 foot power cord rated for 15 amps. I use it only for two laptops and one camera, making a draw of about 5 amps at 120 volts, according to the "input" label on the power supplies.
The 50 foot cord is heavy and I would like to find a lighter replacement. I have seen cords rated for 13 amps that are a bit lighter, but I think I can do better.
If I buy some wire and attach standard power plugs that you can buy at the hardware store, what is the smallest gauge I can safely use, assuming I never try to draw higher than the gear listed above? Would this also be safe for 100 foot power runs, if I connect two 50 foot cords together?
To be clear, I'm in the usa and power would always come from standard plugs.
