In Episode 32 of “EC&M On Air,” Ellen Parson, editor-in-chief of EC&M, highlights some of the most popular technical content we’ve been running recently in audio-only form. In case you missed it, this content was originally brought to you in our EC&M Asks Q&A video series. This week, we’re featuring subject matter expert Harold De Loach, who addresses some of our readers’ most pressing questions about the most common mistakes apprentices make when referencing the National Electrical Code. This includes how the Code book is structured, tips for navigating this massive book when an apprentice is in the early stages of his or her career, how to find the information you need fast, and how to deal with “special permissions” and exceptions.
