2017 Master Electrician Ref.

This is probably the best overall app for electrical references for any on the job Electrician, Engineer, Mechanic, etc that there is out there. If you need any information as it pertains to the electrical world this is the ONLY app to have on your smartphone. It gives you concise information in an East to read and we'll laid out format that's easy to find and reference. I highly recommond it to any person working in the electrical field.

This is a great app to have at your fingertips It up to date with all of the information you need.

I took one star out cause your table for voltage drop wasn't matching with the right answer for one of the questions in your quiz app. I think it was question 75. It goes something like, whats the length of wire for 12 awg with 20 a breaker at 3% drop. Table clearly shows 25’ but quiz app says its the wrong answer. So idk what other things are inaccurate here.
