xiii New to This Edition The following changes were made to the 12th edition of Modern Residential Wiring to strengthen the integrated learning solution and to remain cur- rent with professional codes: • Content and tables have been updated to correspond with the 2020 version of the National Electrical Code® (NEC®). • Chapter 8 has been updated to address code and table revisions as they apply to conductors. • Additional updates have been made in other chapters, where appropriate, to address code revisions to topics such as service equipment and motors. • Up-to-date pedagogical features give instructors and students a learning edge, including questions at the end of each chapter. For this edition, new types of questions include: • Know and Understand questions. These autogradable questions provide an opportunity for students to demonstrate knowledge, identifi cation, and comprehension of chapter material. • Apply and Analyze questions. These questions, also based on chapter content, extend learning by helping students analyze questions and apply knowledge. • Critical Thinking questions require students to make connections beyond the text. These questions extend student learning and develop higher-order thinking skills. • The addition of EduHub, an easy-to-use learning hub, provides the foundation and tools that improve student retention and facilitate instructor effi ciency. For the student, EduHub provides an eBook with text-to-speech capabilities, highlighting, and bookmarking.
