If this were a 2 phase panel, such as almost all residential panels are, it would have 2 hot lines and one neutral. In this case if the loads are balanced the current in the neutral will be zero. With unbalanced loads the current in the neutral is the difference between the 2 hot lines. Because the current in one is 180 degrees out of phase with the other the current from one cancels out the current from the other. Best practice is to try to keep the loads balanced as much as possible.

I've never seen a two-phase residential panel at lowes or home depot.Â* Since they're so common, would you provide a link to one at homedepot.com or lowes.com?
