As you can see, the wires from the supply to the distribution boards on
my portable cabinets are no more than eight inches long and they are
16-gauge. With wires this large and short, the voltage drop will be
very small, and remote sensing wouldn't provide any benefit that I can
see. I thought that remote sensing was useful only when the distance to
the load is great enough to result in significant voltage drops.
