Equipment vs. Systems

[vavelar]

Article 100 defines "equipment" but not "system"
Does anyone know how the NEC defines a "system" as it applies to Article 645?

645.1 – Scope.
This article covers equipment, power-supply wiring, equipment interconnecting wiring, and grounding of information technology equipment and systems, including terminal units, in an information technology equipment room.

Re: Equipment vs. Systems

If the NEC doesn't have to define a word or term for the application as described in the NEC, the literal definition or meaning would apply.

Without opening a dictionary, I would say "system" would mean a group of items, equipment, or methods necessary to complete an assembly or operation.

"The offical electrical dictonary of the NFPA is the IEEE Standard Dictionary of Electrical and Electronic Terms. If the NEC or IEEE does not define a term, then a dictonary suitable to the AHJ may be consulted" From Mike Holts Understanding the NEC, and I believe this is in the NEC NFPA Style Manual...
