In my new location, I need to make a new power cord about 5 feet longer than the OEM cord to reach my power supply. I need to know the wire gage and the anderson power pole sizes to install on the new cord.

Thanks for your help, 73

I'd try to keep the drop at around .5V or less. Adjust your power supply voltage up a bit, but I also wouldn't exceed 14V.

30A Powerpoles should be fine. 50A if you want to over do it.
