This app will lie to you!

Don’t use this app! I work as an electrician and used this app for a conduit fill on a nipple between two panels. I had (4) 350 xhhw and (1) 1/0 xhhw and it came out to 56% fill for a 2 inch emt. Used a 2 inch emt for my nipple and inspector called me on it. I calculated it out via 2020 nec and sure enough it came out to 67% fill over the 60% max. Made me look stupid and wasted time. We’re trained to trust our tools but apparently you can’t this one.

Bring back the calculate button

The old version was better. You didn’t need to have all the info as the app would fill it in when you pressed the calculate button.

Better before

Before this update this app had a Calculate button on it which you could leave something blank and it would calculate it for you so you wouldn’t have to look it up that’s why I gave it to stars
