Thumbs up


KB sparky (Poster #15) This whole discussion revolved around single Phase. In Three Phase, where you are dealing with (Triplen ) Harmonics, not only does the Neutral carry only the unbalanced load. But it triples, and overloads the Neutral. One of the solutions for that problem is to have a (much) heavier Neutral than the Hot wires. Even having a lot of electronic Ballasts can create (Triplen) Harmonics.

I was planning on having the pvc come up from the ground to the bottom of the meter base, and the feeder wires going through the back to the panel inside? Am I wrong in thinking I won't have and LB?? Or am I just confused here.

I am using emt between the meter and panel, and I have the locknuts and the ground bushing already. By plastic bushing, do you just mean the push in type that go inside the emt fitting to stop the wire rubbing? The ground bushing itself has a plastic sleeve inside already.

Oh, you want to compare:

Let's see, one of our instructor is on a NEC code panel, one has a Ph.D. in some branch of engineering, and 2 others authored a book that is used in some apprenticeship programs. Plus one of the guys used to be a inspector.

and just as a side note, some of the classes a couple of the guys put on are so well respected that they have graduate students from the University of Notre Dame school of Engineering attend some of the classes.

So, you want to argue about who has what knowledge available to them?

so, back to my question to you: provide an installation that would allow a #4 neutral on a 200 amp single phase service.
