Grounds and neutrals sharing bus bars

Qualified is often a problem :upside_down_face:

Yes, you’re correct, You do not want the EGC and the neutral to be connected together on both ends which would allow the neutral current to flow on the EGC under normal conditions.

That was answered in the 4th post in this thread!

except they aren’t isolated, I know, hard concept.

Still abit confused about GEC and its potions.

Turning to Mike.
I still have the feeling you are not clear on the differences between GEC and EGC. Will come back after.

A GEC is a single conductor that connects to the ground electrode system at any point. It is a Single Conductor, and as such you cannot CHOKE IT. So if you run it in a ferrous metal, it has to be bonded at each end to make the raceway a part of the conductor. Otherwise it can be ran in plastic or aluminum raceway, or no raceway at all providing it is protected from damage.

An EGC is always ran with its associated phase conductors.

I know NEC 690.47, especially 690.47(D) has caused a fire storm in cycle 2014. It will be repelled. Unless you are using 2014 cycle ignore it. If you are using 2014 cycle conform to get inspected, then correct after inspection. Here are two videos from Mike Holt. They are are long and very specific.

690.47 (D)
690.47 (D)

The 690.47 (D) video Mike has done something he has never done. He point blank comes out and says it is Deadly and the dumbest thing ever to come out of the NEC. John Wiley is taking a lot of heat and lost a lot of respect. If you only watch one of the videos, watch the first one 690.47 (D) It will open your eyes.

Not a hard concept at all. Simply one that is unnecessary to answer the OP. If you want to discuss electrical isolation as a circuit not connected to the ac mains that needs another thread.

You made a claim the neutrals are isolated in the sub-panel in your #4 post – they are not isolated. This was the entire point of the last 60 posts.

WAFI is back :rofl:

I made no such claim. I simply pointed out that to they are not bonded in the sub-panel. To the extent that is true they are isolated from one another at that location. Arguing nomenclature does not answer the OP’s question but merely enhances your own conceit that you have superior knowledge.

Excuse me JP!
The fitting term is “Rat Bastard”

Come on now!
I resemble that remark…With the exception of “Mr.” Rat Bastard…:innocent:

See that the hate committee is back.

I guess, for the majority, it comes down to just knowing yes or no, and not the why. Oh well, such is life. The irony of it all, when the realtors do it, somehow it’s not okay LOL

Isolated in the context of this thread refers to not being connected to the grounds at any point except the service as long as the panel is fed with 4 wires.

I am aware, however, it is technically incorrect and most don’t understand why.

Jim Miley,

You may have a basic understanding of the mechanics of grounding and bonding but you don’t know the terminology and are confused about some basic electrical concepts.

Many of your statements are incorrect. If anyone following this discussion takes your comments as facts, they are only going to be confused.

You are getting defensive, holding on to your misconceptions. You don’t seem to have an interest in learning. My. Advice to anyone following this discussion is not to rely on your comments.

My advice to you is to take a basic electricity course or two. You are polluting this discussion with your misinformation.

Johnny - I have tried to ignore you but you seem to need to be dressed down. I viewed one of your expert reports and you seem to be clueless as how to report on anything electrical. Here are a few examples. From:

And my favorite:

Was it a 75 Amp panel? Maybe a 47 Amp? Is 100 AMPS low?
