controller supply wire size

[nesbit6363]

I built a single element 30amp control for doing ebiab. It is also set up for 2 pumps. My question is what size portable cable do I need to run from the plug to the controller which will be 35 feet of cable. I think sjoow 10/4 will work I just want a second opinion.

Cheers

10 gauge should drop less than 2% over that distance, I think that should be fine and it is the size I would select if I were doing it.

Some EEs out here might be able to provide more professional advice.
