I passed my 02 JW test. This helped me so much. Worth every penny

Help me pass the low voltage test

This is a great book to purchase as an addition to the 2020 NEC. I sometimes have a hard time finding obscure code articles and this expedites the process. Keywords are in alphabetical order and they then site page number along with the code article where the answer can be found. Also it's great for Estimators and Project managers.

Very very helpful in finding things in the text book. Subjects can be very broad and open ended, this book helps pinpoint particular topics and you’re able to get exactly what you need in the text the first time! So glad I got it!

I just used this to pass the administrators exam in my state. That means taking the entire JW test again, then adding major load calculations on top of it. This was absolutely critical to the NEC portion of the test. It worked for finding the really specific and obscure code references as well as helped me verify the ones that I felt confident about.
