This app provides great knowledge for a learning apprentice. If you're just starting or need a refresher, this is an interactive way to learn.

The app is fun to play around on I've enjoyed it for the last couple years. When I need something to do to pass some time I mess around on here. I wish there was a lab that said customer wants 120/240, 120/208, 277/480, etc. Then gave you open or closed bank. Then you had to build it according.
