8 unit apartments and grounding rods


There are rules against multiple services on the same building. There are exceptions, but I doubt this building qualifies. Even if it did, the services would be required to be bonded together.

What do you do? You have multiple threads asking about why certain things are done, not how to do specific things. Are you an apprentice? Where do you reside?

I was waiting for someone to ask me about that. Yes I guess you could say I am an apprentice. I work for a small electrical company in Clarksville, TN. I have been working there for a combined 3 years now. Doing mostly rough in and trim out on residential homes......some small commercial. I have decided to really dive into the electrical trade and hope to one day get my limited license followed by the general license. I have been studying the NEC 2008 quite a bit. As well as basic dc/ac circuits textbooks. Unfortunately the company I am with doesn't exactly hire high brow people. So I find it hard to learn and educate myself within the company. My questions are mostly answered with bullsh"t or someone talking out there ass. Credibility is an issue. I want to someday master this trade and the rest of the company are like drones pulling wire.....basking in te mindless work. Which is ok sometimes......but nothing to gain from it. Everyone thinks they are an electrician. Anyway I do appreciate the extensive knowledge gained here in a short amount of time. Thanks to you as well.

What are the consequences of not bonding the two Rods when they are installed the way I described above. Two separate enclosures being supplied by the same service. Each connected to its own rod

Each enclosure could be at a different potential.

You should really check out electriciantalk.com

That's funny.... I asked a question about ovens being 110v or 240v and a moderator jumped in and recommended I come to this sight. Haha... I guess one of my original questions was a bit to newbish.

Yeah, learn to be thick skinned, obviously some people were born knowing everything.

I'm sorry the question was about a double fed duplex receptacle. But anyway...so the enclosures could end up with different potentials.....or voltage

Doesn't each meter stack have one main disconnect down at the bottom (and four individual apartment unit disconnects, one for each meter)?

Then we have two main disconnects altogether within reach of each other with one service for the building branching to both of them, well within the six disconnects per service and one service per building rules.

Correct me if I am wrong, in order to complete the grounding electrode system, a bonding jumper would have to go between the neutral bus at one main disconnect in a respective meter stack and the neutral bus at the other main disconnect, if not between the two ground rods one connected to each meter stack. A metal conduit between the meter stacks (fastened to the metal boxes thereof) is an equipment grounding conductor, not a grounding electrode conductor.

I highly doubt a 8 apt. building qualifies for two services... 230.2 (B)(1) Might come into play....

No there is no
Main. The service wires connect in an auxiliary gutter and each meter has a disconnect 100 amp breaker

SO where exactly did you tie the ground rod wires into then?
