Was a good app, however the commercial motor calculations do not work. Not sure if its an Android issue. My coworker has the Ios version and it still works, doesnt work on the Android. I will fix rating once the issue has been resolved. (This issue has been fixed if you uninstall and re-install the latest update. Changed to 5 stars. Good job guys! Thank you for fixing this issue)

I have been a commercial - industrial electrician for 32 years. This man is a genius, not only in his knowledge but also in his ability to get it across to you clearly. I read his articles in trade magazines religiously, and they have helped me greatly in my career.

This app is great for learning or practicing electricians, engineers, or inspectors. Can we get a PIP mode for the video series on the mobile app though?

Mike Holt cares about the trade. He wants people to be better at the trade, not just pass a test. The man is a blessing to the world of electricians.

Assumes PVC for fill ratio (extra ground wire required), no option to select EMT. No "tricks of the trade".
