This is awesome. I constantly use my iPhone for Plan Review and Inspections; however, if you are an electrician in the field this is extremely valuable as well. The advertising does not cover anywhere near all the tables and calculators this app contains. T250.122, T250.66, chapter 9 tables, conduit and box fill tables and calculators, motor and transformer calculators. It has all of your outlet configurations, all the NEMA classifications, voltage drop calculator, etc, etc, etc.
For the past several years I have been using several other app, which will no longer work under the next iOS!
Shoutout to the developer; thank you for keeping the electrical industry alive on the iPhone!
Suggestion; if you could also add a Fire Pump calculator that would be awesome!
