Series Location Voltage Drop
  The Series Location Voltage Drop Analysis module is very similar to the main Circuit Load Analysis module in that it automatically sizes conductors based on various conditions to one of the 34 NEC® ampacity tables. It also computes the Line to Line and Line to Neutral voltage drops to IEEE Std 141 exact formula specifications. This module is intended for street and arena lighting where a single cable is used between individual lights (or devices).

Volts' voltage drop computation methods allow for the following:

Varying conductor types - conductors or cables, single or parallel

Varying conductor insulation types

Varying raceway types - EMT or PVC or ....

Varying ambient temperatures from device to device

Varying distances between devices

Varying device power factors

Varying device phases - 1, 2 or 3Ř with a neutral

  This full featured module features a complete array of editing capabilities inclusive of sequence modifications, updating, cutting, pasting, etc. of any entered device with all computations automatically updated with each modification. Additionally, 7 of 34 different information column headers can be selected "on the fly" for a complete analysis of the circuit.

It simply cannot be any easier or more accurate to obtain the correct information the first time.
