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.

Electricity poses a significant danger to firefighters when working with energized PV systems. To reduce this risk, the NEC has implemented requirements in 690.12 that include a rapid shutdown function for PV system circuits.
To learn more about these requirements, read the attached text and watch the accompanying video, where Mike and the Solar PV team discuss the topic in detail.
