For a full comprehension of the material in this course, you should use the NFPA 70®: National Electrical Code (NEC)® Handbook, 2011 Edition in conjunction with the online course module. The final Quiz at the end of each module will only come from the course content, but some of the Self Study questions may refer to the Handbook and your learning will be enhanced by studying the Handbook. This course is not meant to be a replacement for the Handbook or the Code.
