Voltage Drop Calculator

Makes Voltage Drop Calculation a Breeze

This application could also be called "Feeder Sizer" as it provides all information required to size feeders. Colour coding of maximum allowable ampacity values - according to CEC or NEC - helps choose the correct wire size. Voltage drop values are updated on the fly, conduit size is shown and if you size the feeder for a motor, Full Load Ampers for typical motors are built-in.

With rising cost of electricity you may find the "Feeder Efficiency Tip" useful. It informs when it may be beneficial to increase wire size above the minimum required by code. Download.
