Keeping up with the requirements of the Code should be the goal of
everyone involved in electrical safety. The following is what I feel is an
important rule in the 2020 NEC®, complete with
graphics and a video. I encourage you to use it as a training resource for
your organization, and share it with your colleagues.
| Grounding, High Impedance [250.36] |
The content below is extracted from
Mike Holt's Understanding NEC Requirements for Bonding and Grounding, based on the 2020 NEC. Be sure to download the PDF to follow as you watch the video.

Do you know what a high-impedance grounded ac system is, and what loads it can serve? These systems are generally used where sudden interruption of power will create increased hazards, or when a reduction of incident energy is needed to protect workers.
Read the attached text, then join Mike and the video team as they discuss NEC Section 250.36 and the basics of high-impedance grounded ac systems. Download the PDF to follow along with the video.
