Bonding the neutral in a sub panel

[Benji]

Would like to know if you bond the neutral conductor in a sub panel, from the neutral bar to the panel.

Your profile states you are an electrician, this question tells us you are probably not. We are discouraged from answering questions from DIY'ers and those not involved in the electrical trade.

Maybe, maybe not, depends on a few things.

I'll give him the benefit of the doubt and take his word that he's in the electrical trade.

No. No. No!!!!!!

This isn't always true.

As Roger said, there are times when the neutral and ground bond is permitted in a subpanel. Your question is too vague for a proper response. We need more information.

Benji
Give us the information on this installation. Is it in the same building, and how many wires are feeding this panel. I'll still bet dollars to doughnuts that the answer will be No. No. No!!!!
Any takers???????

I just read 250.30 and 250.32 B and I did not see anyhing about a "sub panel".

Check with the navy; they have plenty of them.

In my Navy days, I only had to deal with "target panels."

I know you are not to run a ground!!

Re: Bonding the neutral in a sub panel

Oh I get it:
Target-surface ships are targets for subs.
Still not sure what a sub panel is.
We use the term frequently, but it has no meaning.

In Washington, you can't ever tie them together in a sub panel. Since he signed as Seattle, WA, I thought I'd point that out. Its a state WAC rule and not an NEC one.

Could you give me the rule number? I want to look that one up. If the WAC actually calls it a "sub-panel," then Tom will have to stop saying that that phrase doesn't have any meaning.

Re: Bonding the neutral in a sub panel

No they don't come out and say subpanel, but I think we all know what he means. The WAC stipulates that all feeders to detached structures be fed with a 4-wire feeder. So the 250.32(B)(2) choice is not a choice in Washington.

The WAC says: 032 Two or more buildings or structures.
(1) Effective August 1, 2003, an equipment grounding conductor must be installed with the circuit conductors between buildings and/or structures. A grounded conductor (i.e., neutral) is not permitted to be used in place of a separate equipment grounding conductor between buildings and/or structures.

Sure, Tom knows what it means. He is just channeling "Bennie" again.

But thanks for the WAC citation.

Re: Bonding the neutral in a sub panel

I thought this forum would be better than most of the others I check out for answers. I thought there were pro's, beginners, layman and everything else in between here to help. As usual it is full of insecure so-called pro's simply trying to make all questions look stupid and even make each other look stupid. You know who you are. There are exceptions, of course, like Suemarkdp (or something like that). Bonding/grounding is one of the most misunderstood subjects in the NEC. Even the inspectors in our area can't agree on everything regarding this subject.

It seems to me that your comment puts you directly in the position you are so steadfastly commenting on. And it is only your first comment here????? Well I think that says volumes about you, doesn't it.

You're right. We're hoarding all the secrets, belittling the folks just starting out, and leaving them idiots out in the cold.

We sure don't spend half an hour passing along that vital knowledge so that someone else can pass along that spark. I appreciate your constructive critizism. See you back here for your next profound thought in 2007.
