Reading several thread here regarding subpanels. While the NEC does not have a definition of a subpanel using definitions of similar words can help.
Here are several:
sub·ma·rine
n. 1. A vessel that is capable of operating submerged. Also called sub1.
2. A large sandwich consisting of a long roll split lengthwise and filled with layers of meat, cheese, tomatoes, lettuce, and condiments. Also called sub1; also called regionally Cuban sandwich, grinder, hero, hoagie, Italian sandwich, poor boy, torpedo, wedge, zep.
adj. Beneath the surface of the water; undersea.
v. sub·ma·rined, sub·ma·rin·ing, sub·ma·rines
v.tr. 1. To attack by submarine, especially with torpedoes.
2. Sports To knock down with a blow to the legs.
3. Baseball To pitch (a ball) with an underhand motion.
v.intr. To slide, drive, or throw under something.
Subordinate:
Main Entry: 1sub·or·di·nate \ Function: adjective Etymology: Middle English subordinat, from Medieval Latin subordinatus, past participle of subordinare to subordinate, from Latin sub- + ordinare to order — more at ordain (http://www.merriam-webster.com/dictionary/ordain) Date: 15th century 1: placed in or occupying a lower class, rank, or position : inferior (http://www.merriam-webster.com/dictionary/inferior) <a subordinate officer>
And then there is substandard meaning not up to the expected level.
Which brings me back to subpanel. Since the prefix sub means not at the top level, or below it is easy to extract that a subpanel is subordinate to another panel.
