Along with the term "Noodle" being an ECN "proprietary" term, I have heard a few in the trade use this technically correct term!
I like it, since it lays no claim to a conductor's function - yet places an emphasis on the given conductor as to it's "difference and complexity"
Simply, it does not say a word about any common conductor / center tap current flow situations, but does make a claim that this conductor is some how different than the others!
Hence lies the crucial factor: Grounded / Identified Circuit Conductor!!!
Be it a Center Tap, a Common on 4 wire Wye, or a "Corner Grounded" Delta - the term "Noodle" (To ME) distinguishes it from any other Conductor, but does not label it's function.
Now on the other hand, trying to use a piece of Pasta for a circuit conductor may lead to problems - so uncovers the flip side of the coin regarding rampant spread of terms without an underlying definition.
As long as no person can be hurt trying to use Pasta for a conductor, there's not too much of a safety hazard - only a head spin for the lucky ones trying to shoot trouble on that installation!
