Very good app! It's not intended to replace a good education and a copy of the current NEC though!
Indispensable, used daily...
App is an excellent tool for any Electrician would buy again if I had too
Great app but wire sizing is not right. And dwelling conductor size should have on column marked copper and one aluminum
Wish it had NEC table 3.10-16
Very handy and useful
Very useful app. The best one out. Updates all the time as well.
Can get a lot more, much easier to use, for free, from other apps. Save your money.
Simple to use and very helpful. Strongly recommend.
Use it a good bit at work..nice app
