Comments on Southwire® Conduit Fill Calc for Android

★★★★★ doug worth · May 25, 2022

Easy to use. Lets you know when not nec compliant. Fast. Love it.

★★★★☆ R. Crewse · Dec 16, 2020

It's easy to use and so far accurate. My only problem is with the scrolling. It is finicky about where you must touch the screen to scroll correctly. I would recommend this app.

★★★★★ Rodgerick Williams · Nov 11, 2025

Easy to use Best Conduit Fill App! I know I have been using this App for at least 10 years!🔥

★★★★☆ John LaPointe · Feb 3, 2025

I also cannot get past the agreement page. The scaling is off to a point where I see the agree and disagree on each side, but it overlays over my info bar at the top and don't do anything when you tap it. Update - South wire reached out and asked me to update the app. I then was able to get past the agreement page. However, I was having trouble getting it to calculate, and they then instructed me to hit the + at the bottom of the screen to add another conductor, and it then calculated.

★★★★★ Toby Hollander · Jun 27, 2026

The easiest way to size conduits to NEC code.

★☆☆☆☆ Bryce Larter · Dec 30, 2024

Can't even "Agree" to terms and use the app. Formatting and location of button does not work with my phone.

★★☆☆☆ R C · Dec 13, 2023

Calculator is accurate, but CIC disclaimer needs to go. It takes up way too much space on the screen. I only get one conductor entry and have to scroll. More often than not, I end up selecting a cell entry rather than scrolling. And I cannot see all conductor data without scrolling. Very frustrating!!! Guess I'll have to look for another app....

★☆☆☆☆ Thomas Buis · May 9, 2026

The app did not function. Drop-downs accepted conductor size and qty but fill info not provided

★☆☆☆☆ Brian Weaver · Sep 12, 2021

Doesn't offer enough areas to fill for more wire, didn't show arrow to move on to get answer.

★☆☆☆☆ B · Jul 11, 2024

Calc did not work on my android for #80 conduit, 12 sols, then 7 conductors
