   thank you Tony, there is little to be found about load center lengths.   
   mean-current distance may have produced some results. the suggested 5% max in   
   the NEC is interpreted in different ways from county AHJ to county AHJ but   
   would be the suggested    
   acceptable voltage drop from the feeder to the end of a branch circuit. from   
   the final over-current device (branch circuit) to the end of the circuit, it   
   is 3%. i question the load center length method as you do. for multiple loads   
   on branch circuits, i    
   was taught to find the drop between the source and load 1, the drop between   
   load 1 & 2, the drop between load 2 & 3, then add them together for the total   
   voltage drop. i had never heard of load center length until recently and this   
   thread was all i found    
   besides the nccer curriculum for level 3 electricity where i finally saw an   
   example of the math.as you said, i question if the mean current-distance is   
   accurate for a trouble free installation when multiple loads are included
