What is distribution

[Pinnie]

I’ve heard the word distribution or distribution wiring thrown around. What is that referring to. It’s not defined in article 100.

I'm assuming you are not talking about grid distribution, and instead about distribution owned by a utility customer (such as within a building).

Colloquially, I think people are often referring to feeders when they are talking about distribution. The Article 100 definition of "Switch, General-Use" does suggest that branch circuits are different from distribution.

Switch, General-Use. A switch intended for use in general
distribution and branch circuits. It is rated in amperes, and it is
capable of interrupting its rated current at its rated voltage.

Also, see this thread from yesterday about distribution equipment:

So it’s not defined I’ll just assume it’s the dictionary definition
