Parallel conductors are when multiple smaller wires are run instead of one larger one for circuits that need high current. It is only allowed in very narrow circumstances that usually only apply to commercial/industrial work or some large residential services. If the parallel conductors are installed incorrectly it can cause one of the smaller wires in the set to overload and melt/burn.

I can think of a few situations where someone might accidentally parallel conductors in residential branch circuit wiring. The biggest hazard in this case would be that two or more breakers might energize the same wire which is a safety hazard for someone trying to work on the wiring as it is not obvious how to safely turn off the power.

THE POCOS incoming neutral on their end before weatherhead has 2nd wire ,#4 copper,attatched an that one runs along side of outside of pole ,the primary neutral is in pole to same meter box.Of coarse thats theirs, atop ,,an its how it was done many many years ago so im told .
The #4 terminates in box on its own. ,an the main neutral has ground bar lug to box with the ground wire lug on it ,ran from ground rod .
Was told its double bonded by tech that hooked it all back up /inspected.
I was just wondering if this is considered as parrelel neutral , since they run side by side to same point .An if there are any dangers to it .
Thanks

Sounds like a parallel . I don't know why this passed inspection . It should have just been a bond for the weatherhead to the neutral.

Are they allowed to rehook the wires ,at pole,an turn power back on without it passing or does there have to be someones signiture,or a inspectors ok, that it is safe to re connect,reinstall meter , an restore power ?
is there any danger to what i have ?
I can only terminate it on my side..
Thank you

here are a few pics.
I couldnt get them to load on last post.
Left #2 lug is coming from neutral feed on their end/right lug wire goes to ground rod.

So should that one from their end have joined in on a 2nd lug ,where neutral bar is, going to ground rod instead of independantly in meter base?
And it is considered a parellel neutral/any dangers?
As shown inlast pic its in operation now.
Thanks

What they did is ok. It looks there is a bond connection from the neutral to the right lug bonding the neutral to the meter pan. Those are single wire lugs so two wires should not be in one of them.

Never seen the ground in PVC before.

That's just plain crazy. But you do whatever it takes to pass inspection.

I've seen what I consider a bit crazy a few times too. One of the craziest things I remember seeing maybe 10 years ago was outside the back gate of Ft. Campbell Kentucky, in Clarksville, TN. I recall seeing on several houses the GEC from the ground rod climbing the side of a house and terminated at the utility's neutral connection at the weatherhead. Craziest way to ground the neutral at a service I have ever seen.

Maybe that's the same as the OP was describing, I see he is also from TN.

Is this how it should have been done?
Or the way it was done in many homes 25 plus yrs ago?

And is this considered as "parrelel neutral" too?

I have never seen a ground to neutral bond at the service head ever.
It's always done in the meter pan.

I think that is how some power companies required it to be done. The homes in Clarksville, TN that were done that way were built in the '70s. Where did you get that diagram? From your power company?

Rules change even with the utilities over the years. 35 years ago in my area the GEC wasn't allowed to even enter the meter socket, but today the GEC from the ground rod is terminated inside the meter socket at the grounding lug at the neutral .

Thumbs up

Talked w local electric inspector..
Yep thats how these homes were wired a while back!
An yes thats appropriate location for that#4 copper off weatherhead .
.
And it is NOT a Parrelel Neutral!

Thanks again for the feedback.
Hope this helps others who STILL have that older #4 copper on their weatherhead ✔
