MOTM

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.
