AC Wiring Diagrams and Terms

Posted by John T on May 09, 2013 at 05:21:43 from (216.249.82.117):

A while back somewhere down there below, was a question regarding a household fan wiring diagram and the terms used describing where to attach which wires. As I explained, the techy terms used were universal in nature (Fan made in China maybe???) intended for electricians and engineers who were familiar with the terms and unfortunately, were NOT written for the average non electrical lay installer. HAD I WRITTEN THE INSTRUCTIONS I WOULD HAVE USED THE COMMON TERMS (Hot, Neutral, Ground) WHICH BOTH AN ELECTRICIAN AND NON PROFESSIONAL COULD HAVE UNDERSTOOD grrrrrrrrrrr

So, if yall come across such an appliance (with instructions you dont understand) and want to wire it up, here are a few definitions. These are the words (or close to) used in the instructions

1) GrounDED Conductor

Thats what electricians and engineers and some lay persosns know as the Neutral (White). Its called a GrounDED conductor because a) Its a normal return current carrying "conductor" and b) At BOTH the Transformer and at the Service Entrance its attached to a copper wire that leads to good old mother earth (suitable grounding electrode like driven rods etc), i.e. its "grounded" AND its a "conductor" HMMMMMMMM a GrounDED Conductor who would have thought lol

2) UNgrounDED Conductor

Thats what Electricians and Engineers know as the more common term the "HOT" (Black) conductor. Its again a normal current carrying "conductor" HOWEVER unlike the Neutral, its out at the other end of a transformer winding, WHICH IS NOTTTTTTTT GROUNDED. Its NOT Grounded and its a conductor, hence its referred to in the trade as an UngrounDED Conductor HMMMMM

3) GroundING Conductor

Thats what electricians understand and could call the Ground (Green or Bare). Its a) A "conductor" but its intended ONLY for b) GroundING purposes Hmmmmmmmmm a "GroundING Conductor" . Its sole dedicated and only purpose is to provide a direct dedicated low resistance path back to the panel ONLY FOR FAULT CURRENT so the breaker trips deenergizes the circuit and can save a life. NOT intended for normal return current ONLY for fault current!!!!!!!!!

SO a GrounDED Conductor (White Neutral) is nottttttttt I repeat NOT a GroundING (Green/Bare) Conductor

NOTE DISCLAIMER at least thats how I was taught and terms sometimes (NOT always mind you) used when I had to attend NEC Seminars, but maybe in other parts of the country and other jurisdictions etc electricians and engineers use different terms??? I CANT SPEAK FOR EVERYBODY, these are just terms I learned SO NO WARRANTY take this with a grain of salt and call things whatever your little heart desires lol

Surely by now yall understand mixing and matching and substituting Neutrals (GrounDED Conductor) for Grounds (GroundING Conductor) and vice versa can be a potential hazard and could get you killed (Plus a major NEC safety violation) !!!!!!!!!!!! But you dont have to take my word for it and are free to do as yall please AT YOUR OWN RISK HOWEVER!!!!!!!!!!!

Best wishes, keep safe, n God Bless
