Panelboard outlet

[kwired]

current never "leaves" the wiring system, it goes one way, and returns the other way, it never leaves. current can only occur in a loop.

the current vectors are identical when looking at the current flows through each conductor at any given time. note though, if you look only at one conductor at a time, at any time t current exits the panelboard but it enters the util equip, at that same time t the current vector on the other conductor is simply cos(180) in direction and cos(0) in magnitude, entering panelboard & exiting util equip.

so at what point does current "leave" the wiring? there is no point when you apply current vectors to AC or DC. current is exiting and entering both sides of any closed ckt at any time t, except when the current phase hits the zero crossing, etc.

Part of the "loop" is the premises wiring system. The other portion that completes the "loop" is beyond the "outlet" The outlet contains all "poles" of the circuit, multi-phase circuits will have more then just two wires, as do single phase "multiwire circuits"

Take a luminaire. The exact location of the lighting "outlet" is not always completely as clear as a receptacle outlet is. But somewhere near the point of transition from "premises wiring" to the luminaire itself is where the "outlet" is. Most of the time we don't really care where the exact location is, just an approximate location of the outlet is good enough.

the code writing folks should know what the terms are and how things work, yes?

You do understand that, in most cases, the "code writing folks" are those of us who submit Pubic Inputs (formally known as proposals).

then maybe let the engineers review 1st

"us" are not the folks who finalize it and put it into the book

wordsmithing is important in many technical areas, NEC is one of them.

Well if engineers were all that, we wouldn't need plan checkers. :roll:

We don't need no stinkin plans.

Plans? What plans? Why'd ya have to go confusing everything with plans?:slaphead:

It they would draw them after we are finished, instead of before we start, the plans would be correct

LOL....Reminds me of the millwrights where I used to work. They would set and anchor a new machine tool, THEN snap chalk lines around it. Looked perfectly placed every time!
