Krista Biason's most recent article for EC&M Magazine focuses on the changes in the 2017 NEC regarding the shutdown requirements for the prime mover and how this requirement relates to other NFPA codes.
Most of my previous articles have focused on big electrical “system” issues, complex design issues, or issues of controversy — but the topic for this article is a bit different. I want to focus on a single Code requirement — the shutdown requirements for a prime mover (aka, generator). The original intent of this article was to quickly highlight a change in the 2017 NEC, but being a Code nerd I started crosschecking other Sections in the Code to validate alignment of this new directive. Once I started doing this, the “simple” topic became significantly more complex.
