I'll just shut up............
After reading all the posts in this thread , I don't see why you are all stomping on Cletis, when you all missed the important fact: No Cletis, you would still need to have a fault before all the metal in the house becomes "hot". However you will cause the remaining two power legs to have voltage swings dependentCan anyone further simplify the distinction between a neutral and a grounded conductor (branch cir. neutral v.s. service grounded conductor (some call neutral) ??
If someone goes up and cuts the grounded conductor on line side of service drop what would happen inside the house ??? Everything metal in house gets hot ??
Have you ever seen this happen? Would the plumbing and such become energized?After reading all the posts in this thread , I don't see why you are all stomping on Cletis, when you all missed the important fact: No Cletis, you would still need to have a fault before all the metal in the house becomes "hot".

on the load imposed on either of them being unbalanced. So if the loading is a little unbalanced, the voltage will be a small swing up or down on one side, with the opposite and equal swing away from 120 v to ground on the other leg. A heavy load like 70 amps or so and you are going to see some dangerous swings up and down on the two remaining conductors, which can then cause electronic devices plugged into the system to start burning. It ain't good....
Bout a hundred times would be my guess. To further add, the water piping system from the point where the gec clamp is connected to the other structures nearby connected likewise will carry your unbalanced return current (a bunch of it anyway) so the water piping system can have potentially fatal current in it, regardless of any ground fault or no ground fault in the system. But unless the interior piping has additional places in it that are "grounded" that piping downstream of the gec connection point should not see a current flow. However lots of plumbers install copper water pipes without insulation on them under slabs, so........Have you ever seen this happen? Would the plumbing and such become energized?
For most of us, the neutral is the grounded conductor. I was once asked what the difference was between a ground and a neutral. My answer was the ground should only carry fault current and the neutral carries current during a normal operation. The reason I answered this way is that most of the time, the neutral and ground are at the same potential and if you hook your load to a "hot" and a "ground" it will work (although it creates a condition for someone to get shocked).
True, and the phase conductors are at the same potential as the neutral at the zero crossing. I didn't think we were getting this technical though.The Neutral and grounding conductor are the same potential, ONLY, at the neutral bond connection or when there is no load on the circuit.
Grounding conductors are NOT neutrals. A conductor that is intentionally GROUNDED at the service is either a neutral or a grounding conductor. The conductor that is intended to carry circuit current is the neutral.So, some grounding conductors are neutrals and some are not?
Are all neutrals grounding conductors or none so some??
Is a conductor of a corner ground 240V delta neutral or grounded conductor or neither ?
Neither. It is the grounded conductor.So, on a corner grounded system say when the C phase is grounded is it called the grounded neutral conductor or a grounded phase conductor ??
Then what's up with this I lifted off of an IAEI articleNeither. It is the grounded conductor.
It's not a neutral because there is no voltage-neutral point in a corner-grounded delta system.
It's no longer a phase conductor because it's been grounded.
It's symantics: To the code, it's a grounded conductor.
Any leg or phase of a transformer can be theoretically be grounded, so I don't see much value in the term "grounded phase conductor." It's like calling one side of a control transformer the "grounded hot leg."
