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 2023 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.
| Auxiliary Grounding Electrodes [250.54] |

Grounding electrodes that are not required by the NEC are called “auxiliary electrodes” and are connected to the equipment grounding conductors.
When installing an auxiliary grounding electrode, you are not required to bond it to the grounding electrode system, the grounding electrode conductor doesn’t need to be sized in accordance with 250.66, nor is it required to have a resistance of 25Ω or less.
Read the attached text and watch the video where Mike and the team discuss the “non” requirements of NEC section 250.54.
