Can someone help me a voltage drop question. I have a free air feeder 2/0 aluminum total load on wire 155 amps
spand is 700 ft. Off of the drop came down with #6-3 rx wg to a temp panel typical of 4 total. Question is at the last panel which is 725 ft away from main panel voltage at panel has no loss and amps at last panel is 40. Does voltage drop only occur at the furthest distance and load or total load on total distance. Sorry I hope I explained it correctly. Thanks

The voltage drop comprises the entire run.
To my knowledge you would need to break it down into segments.
Take the total load from the origin to the 1st "tap" and determine the voltage there. From that point take the load of the remaining panels to the second "tap", the recalculate to the third, and last.
Does that answer your question ?

Yes that is exactly how I thought but got a little confused. Thanx much
