grouped disconnect switches

[brown]

Service disconnects for a building are to be grouped together where six or less are installed.
I am upgrading a service from 200 amp to 400 hundred amp. It is an existing car wash building. There has been an added automatic car wash building attached to the existing building.
Can I reheat the existing 200 amp main breaker panel on the opposite side of the wall from the service and than install a 200 amp disconnect on the outside wall next to the service to feed the new building? They are two seperate buildings but the new one butts to the existing building. :roll:
If they were the same building then they should be grouped together. Can I place a perminate sign next to each disconnect explaining the situation?

Re: grouped disconnect switches

If the two buildings were separated by a two hour fire separation then you could have two services at different locations. Each building is now classified as a separate structure.

Allowing you to install a perminate sign to identify the two services would up to the AHJ.

If there were no rated fire wall, then I would assume that AHJ would require two fused disconnects at one location with Grounding Electrode conductors properly sized and connected.

Under Art.230.2 If the building in question is one building you can't have more than one service to it unless it falls under (A)thru (E) of this section.

Be careful what you are saying, I think you are trying to confuse terms. Read the definition of "service" in Article 100, then read 230.2 and say either service drop or service lateral in place of service wherever the word service is used. I would be willing to bet that you will change your mind about your understanding of that section.
