However no matter what electrical engineers , electrical inspectors, law makers and knowledgable electricians understand about electricity . There is always some jackleg electricians that think they are smarter and know more than the fore mentioned persons.
The jacklegs are pretty quick to tell you if they manage to get something to work. However they don't talk about shocks , fires, burned out equipment, smoke and non working equipment .
The jacklegs are lothe to admit they don't know and they don't want to learn either .
Neutral is an insulated load current carrying conductor . Returning load current from either Line 1 or Line 2 back to the Center tap on a single phase utility transformer .
On a three phase Y transformer, the neutral carries load current back to the Center point . From loaded supplied from phase 1 , phase 2 or phase 3. Note the use of "phase" instead of "line ".
The ground system is not a load current carrying system. Usually is not insulated either . The ground system is to hold anything connected to the ground system as close as possible to "ground or earth" potential/voltage . Metallic items such as motor housings , electrical cabinets, water pipes, milking equipment etc.
That is also why there is a ground bond to neutral to HOLD the neutral conductor's potential down to ground/earth potential.
If somebody tells you that the ground system is supposed to carry load current . And if they won't change thier minds when told otherwise. Note the moment because you have just been talking to a fool. Walk away and disregard what ever they had to say.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
