Quick Voltage Drop Calculator

Calculate voltage drop in an instant. 

The nVent PYROTENAX Quick Voltage Drop Calculator allows you to quickly calculate voltage drop based on: 

  1. Ampacity 
  2. Cable size 
  3. Circuit length 

Your calculate drop accounts for line to line voltage drop in a three-phase system under normal conditions, and includes an optional calculation of drop in a fire zone under fire conditions. 

Eliminate the need for manual calculations and start calculating now.
