We had the same service entrance at a hospital.We had to shut it down so the poco could crawl in there and install a pulse meter.Although the FPE scare didn't include it management called in an outside contractor to open the main for third party liability and parts would not get here for at least two weeks.Our guys had to start the emergency generators in load test to let the automatic transfer switch shed the load before the mains were opened.Anyway we've had trouble before and at one point ended up building a breaker box that sat in front of the panel on the floor for a month until a new one was made maybe they still can?.It was in fact because of inspection that we had to do this they would only allow listed replacement parts with no modification.Otherwise they said it would have it be checked out by their special permission devision at a cost of $200.An inspector shows up and tells you what to do.They don't want you to cut into the cabent door ever.
Like HighPotter said get the manufacture involved or make the engineer get them and find the proper breaker then call inspection with all information on the parts.
Honestly on something like this i would drop it back in the engineers lap.Isn't device selection and selective coordination his problem anyway? Around here the engineer anwers to the inspector.
