NEC 210.6 Branch-Circuit Voltage Limitations

[philhurtgen]

Hey, guys! New user here. I'm an electrician in Indiana currently studying the NEC for my journeyman's license, and I have a question about article 210. In section 210.6(A), the NEC references "dwelling units" in regards to some voltage limitations for branch circuits. What I'm unsure of is whether the use of "dwelling unit" here is a blanket term for all types of dwelling units defined in article 100, or if it exclusively applies to the "single unit" type dwelling units, in which case we're only talking about hotel rooms and the like, and residential homes are excluded. Can you guys help me out? Thanks!

"Dwelling Unit" is used throughout the Code and it always falls back to the Art 100 Definition.
In 210.6 it's a dwelling unit as defined (homes, apartments, etc) and in this case they added guest rooms and guest suites as they might not fit the dwelling unit definition as they may not have cooking facilities.

I would like to add to augie47’s comment.

In the 2020 NEC, at the beginning of each article you will see, General, Scope, and Definitions.

Check the Definitions at each article, and you will see where there could be one or more given.
It may also state , “ The definition in this section shall apply within this article and throughout the Code.”

Or it may state,” The definitions in this section shall apply only within this article.”
Article 324 is like this. 324.2 Definitions has 8 things listed , as an example.

Just a heads up. Good luck with your studies.

That’s annoying. So we had a big section of definitions all in one place and now it could be ANYWHERE if it says “throughout”? That’s crazy.
