In Episode 39 of “EC&M On Air,” Ellen Parson, editor-in-chief, is highlighting some of the most popular technical content we’ve been running recently, but this time brought to you in audio-only format. 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 which definitions in the National Electrical Code should be mastered first, including technical terms and how to apply them in real-world applications; what specific language can be confusing and why; and what terms every electrical apprentice should have a basic understanding of in order to be successful. He also go over best practices for navigating the Code book most effectively.
