Please let us know what the final decision on this one is.
On the original inspection there were the two 200amp breakers that were each feeding a 42 space subpanel that were both empty [the rough install was yet in the future]. In the double column push-in section of 12 KOs there was a two pole 100, a two pole 60, a two pole 40, and a two pole 30, and four KOs still not knocked out. No labeling on the panel. No contractor on site. No loads calcs or prints on residential projects in my building department.
So we have 200, 200, 100, 60, 40, & 30 which equals 630 amps of breakers.
The service conductors werre parallel 4/0 AL.
I red tagged it. My explanation stated the max 6 disconnect rule and listed 230.71 and inadequate protection on the service entrance conductors [for which I didn’t list any code book numbers which I’m sure will cause a couple of people here to blast off straight thru the roof into a tirade of legal jargon after which I’m planning on ignoring them completely so that we don’t get another 5 pages of back and forth that accomplishes absolutely nothing.]
90.4 wasn’t listed on my writeup. As a matter of fact, I have never listed 90.4 on
any writeup in the past. The discussion about 90.4 was just something that was in one of my original 4 questions, it was never on any write-up.
Regardless of how long and hard Mike wants to argue against it, at that point the service was failed by the AHJ. The “ball” then moved to the contractors “court”. It was his move. His first move was the most logical, he called me and tried to talk me into changing the call. “Ball in my court”.
I asked for input from Seimens. “Ball back in the contractors court”.
It took 3 to 4 days of calls that rolled into voice mail and emails from both me and the contractor to get a Seimens rep to call me. I talked to several reps and was quite surprised at their lack of any response of substance. Their central point was basically: “We send them out this way at the time” which didn’t strike me as particularly helpful. I didn’t think I should change the call, so I didn’t. “Ball back in the contractors court”.
He went to the next level in the Ohio AHJ pyramid, the
chief ESI in my department. As a matter of fact, I suggested to him that he should do that. That move was also verbal over the phone. I transferred the call to the chief ESI right then and there.
The contractor made his case to my department chief ESI who was very adamant [and still is] that this is a violation of 230.71. The chief added the point of 90.4 that he was not going to accept MLO service equipment with more than 6 KOs. At that point the failure of the service was upheld by the second level up of the AHJ. At this point it was also out of my hands and beyond my authority. Even if I had decided that I had made the wrong call, I couldn’t do anything about it, other than talk to the chief. I was “out of the loop” officially. It was now again up to the contractor to decide his next move. “Ball back in the contractors court”.
The contractors next move “up the pyramid” would have been simple and quick. The next level is an appellate panel hearing held right in the building department building. I know the panel has at least one engineer and one contractor [GC], so it opens up the process to input from a greater number and types of sources. I can't remember anything else specific about the panel. I believe they get that meeting scheduled very quickly, if it is requested. For this level the contractor would have to make a request for an appeal in writing. It could also be expedited by him delivering it directly, emailing it, or faxing it to our department or the office of the county commissioners and skipping the US mail.
I really wish he had taken that step because I really would have liked to find out how they would have decided. But the contractor called me Friday to say that he had changed the panel and wants another inspection on Monday. I’ll see when I get there if it has a main or is a MLO with only a max of 6 disconnects possible.
Because the contractor didn’t take the next appeal step, even if I change my mind about 230.71 being max 6 installed and not max 6 capability, this will have no effect on the other ESIs in my department nor any effect on the chief ESI. In conversation with my fellow ESIs, two of them [one of whom is the chief] have already stated that they will fail
commercial MLO service equipment MDP if there is a capability of more than 6 disconnects.
I feel very uncomfortable with that stand because I don’t see adding a commercial MDP bolt in disconnect/breaker and constructing a conduit run thru the building as being equal to a homeowner sliding in another breaker or two or even a half dozen more. This discomfort with their position was the reason that I started this thread.
I wonder if me explaining all of this helps anyone understand why it would help me to hear answers to my 4 questions
and any reasoning that would go with those answers.
I’m also planning on bringing this up for open discussion at the next local IAEI meeting.
