Electricians and Electrical Engineers with this tool can quickly calculate and estimated voltage drop. The National Electrical Code requires a drop of 5%, based upon voltage, length, amperage this tools allows you to select the wire you need to meet the Electrician and Code requirements.

- Copper or Aluminum Wire
- American Wire Gauge Standard Wire Sizes
- North American Standard Voltages (AC & DC)
- Spin Wire Selector

This Calculator is a voltage drop estimator that can be performed in one screen with simple data.

Do not buy! Crashes constantly very limited functionality, it does NOTHING required, cant even see what wiring its trying to use

This app freezes all the time

I want a refund

Consulting Engineer

Voltage Drop Calculator?

I agree with actual engineer, the results produced by this program do not match the results generated by a respected desk top program. I work as an electrical consulting engineer in the electrical construction industry. In my tests with ac systems, the results produced by this program were only half of the values created by a program that accounts for resistance and reactance. I can only assume the program calculates using only resistance.
While the user interface of this program looks great, the results are troubling. Another drawback is the program won't allow for parallel conductors. I realize that conductor length can be divided by the number of conductors per phase but if I am going to email results to someone why should I have to explain why the conductor length does not match the actual circuit length. I hope this program will be updated so that I can feel confident the results are correct.
