In Episode 45, Editor-in-Chief Ellen Parson is highlighting some of the most popular technical content we’ve been running recently, but this time brought to you 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 Randy Barnett, who addresses some of our readers’ most pressing questions about temperature limitations, general requirements in the NEC as well as the confusion that often surrounds grounding electrodes.

Randy takes a look at Art. 250 and breaks down the eight types of items you can use for grounding electrodes.
