Because electrotechnology changes continually, definitions (vocabulary) in its best practice catalog change continually; not unlike any language on earth that adapts to the moment and place.
The changes reflect changes in technology or changes in how the technology works in practice; even how the manufacturers create adaptations to field conditions by combining functions. Any smart electrical component has a digital language embedded in it, for example. We need not overlook “body language” either.
Consider the 2023 National Electrical Code. Apart from many others the NEC will contain a major change to Article 100 (Definitions); the subject of elevated debate over the past three years.
When we refer “language” we must distinguish between formal language, informal language, colloquial language and dialect which may differ the language spoken, language written at the office and language used on the job site. “Terms of art”

Are these terms (or, “terms of art”) best understood in context (upstream articles in Chapters 4 through 8) — or should they be adjudicated by the 14 Principals of Code Making Panel 1?
Code Making Panel 1 has always been the heaviest of all NEC panels. As explained n our ABOUT, the University of Michigan held a vote in CMP-1 for 20+ years (11 revision cycles) before moving to the healthcare facilities committee for the IEEE Education & Healthcare Facilities Committee. Standards Michigan continues its involvement on behalf of the US education facility industry
To serve the purpose of making NFPA 70 more “useable” we respect the Standards Council decision to make this change if it contributes to the viability of the NFPA business model. We get to say this because no other trade association comes close to having as enduring and as strong a voice: NFPA stands above all other US-based SDO’s in fairness and consideration of its constituency. The electrical safety community in the United States is a mighty tough crowd.
If the change does not work, or work well enough, nothing should prohibit reversing the trend toward “re-centralizing” — or “de-centralizing” the definitions.
Public input on the 2026 Edition will be received until September 7, 2023.
