Two services to a building

[upstatecontractor]

I was looking for some input about installing a second service to an existing building> The situation is this< there is an existing 400 amp 120/208 3phase service which supplies and existing restaraunt in a small strip building (3 stores). The service enters the building overhead. The restaraunt uses the entire 400 amp service. The owner now wants to bring an additonal 600 amp (underground) service to feed the other 2 spaces . the service will be at the same location as the overhead. He claims the utility company gave him permission....am i walking into a nest of bees?

No you are not. As long as the mains are grouped and there are no more that the 6 throws allowed you are good to go.

I do believe I would confirm with the utility to make sure, but to have more than one meter on a strip mall type building is pretty commen.

Depending on type of construction, each occupancy can possibly be considered separate buildings and if so each can have its own individual service.

Otherwise there is nothing wrong with what is proposed in the OP.

Technically the OP is not adding another service, when all is done he still will have one service with two disconnecting means, he is allowed up to six disconnecting means.

Sounds to me it would be an entirely new service with meter socket, should be cheaper than taking out existing metering and placing one with CT.

Make sure you don't violate 230.2 or you meet the special conditions.

Somehow I missed the fact that the additional capacity was being added via underground. That does change things some. I honestly have never been in such a situation where it would be desirable to not supply everything from underground in that type of instance - even if keeping the original 400 amp disconnect intact.

So would he need to check with building planning and see if it is listed for multiple occupancies? Or AHJ to see if it was allowed (special conditions)?

In most cases it is probably not an issue but building construction can come into play here also.

By the way, I apologize for the yellow, I did not realize it was so hard to read. I will go darker from now on.:happyyes:

You have to learn somehow, at least you didn't use white

Ahh, the old secret message. Great trick for defeating the ten character limit in the old forum format. I wish it was still around. It was fun knowing how to defeat it.
