NFPA 70: National Electric Code 2014

Tabs and Highlights

These 1 Exam Prep Tabs are based on NFPA 70: National Electrical Code, 2014.

Each Tabs sheet has five rows of tabs. Start with the first tab at the first row at the top of the page, and proceed

down that row placing the tabs at the locations listed below. Place each tab in your book setting it down one

notch until you get to the bottom of the page, and then start back at the top again. After you have completed

tabbing your book (the last tab is usually the glossary, appendix, or index), then you may start highlighting your

book.

Special note to our Students: If you are a 1 Exam Prep student, here is how to really get the most from these 1

Exam Prep Tabs. Follow the above instructions, but before placing the tab, find the tab's topic in the outline of

your appropriate module. Now locate and highlight several items listed in the outline just before and just after

the topic. See how the topic fits in the outline and how it relates as a concept to the broader concept spelled out

in the outline. If you take a few minutes to do this, when you take the test, key words in the test questions will

remind you of where the information is in the manual!
