1 Exam PrepNFPA 70: National Electric Code 2014Tabs and HighlightsThese 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 proceeddown that row placing the tabs at the locations listed below. Place each tab in your book setting it down onenotch until you get to the bottom of the page, and then start back at the top again. After you have completedtabbing your book (the last tab is usually the glossary, appendix, or index), then you may start highlighting yourbook.Special note to our Students: If you are a 1 Exam Prep student, here is how to really get the most from these 1Exam Prep Tabs. Follow the above instructions, but before placing the tab, find the tab's topic in the outline ofyour appropriate module. Now locate and highlight several items listed in the outline just before and just afterthe topic. See how the topic fits in the outline and how it relates as a concept to the broader concept spelled outin the outline. If you take a few minutes to do this, when you take the test, key words in the test questions willremind you of where the information is in the manual!1 Exam Prep TabSectionContentsDefinitions100Electrical Installation110Grounded Conductors200Branch Circuits210Branch Circuit Calculations220Outside Branch Circuits225Services230Overcurrent Protection240Grounding and Bonding250Ground Electrode Conductor250 IIIBonding250 VEquipment Ground Conductors250 VISurge Arresters280Wiring Methods & Materials300Conductors for Gen.
