Southwire® Voltage Drop Calc

This is a great field use tool to figure out wire size on the fly!

I use this app for my job as an industrial electrician. It works great! It is a time saver.

It’s good. Thanks to Southwire for allowing me such generous computing capabilities on my iPhone. Five stars earned.

I use every day in the field.

Awesome app

Nice to have this Much safer then trying to remember or look up to fine the correct information and it’s right on my phone Thank you for offering this By the way your wire is all that I will use

Nice to be able to sit on the site and run the various options to figure out what size cable to run

The app was easy to use and it comes in handy on a job site

The app simply does not work. The screen is mostly locked. The only part that works is the review. GFM

Can't get app to work.
