(a) General. The sevice disconnecting means for each service permitted by Section 230-2, or for each set of service-entrace conductors permitted by Section 230-40, Exception No. 1, shall consist of not more thank six switches or six circuit breakers mounted in a single enclosure, in a group of seperate enclosures, or in or on a switchboard. There shall be no more than six disconnects per service grouped in any one location.
And it's "substantially and materially similar" in the '99 and '02 codes...
Dangerous? Probably not. Practical? Well, if not having to appeal for a zoning variance due to non code compliance when you go to sell the building is practical...

Guys, This is quite common in No. VA. The use is for townhouses, or rows of warehouses. The POCO does not (will not) hit them individually, so they choose a common location.
How is it justified???? Why not? Each service has only ONE disconnect (though agreed this one looks as if it may be a bit different), it is only multiple services grouped at a common location.
One of the reasons I don't "pop" on here as much - actually, I do, I just don't answer as many questions- is we do not use the 2002 code, we're on the 99, and I have not updated my class book yet until I know which code we will use. If there is a reference in the 2002 prohibiting this, let me know.
Not really dangerous, very practicle...but still a violation in my opinion. Max number of Discos should be 6...7 if one is used for a Fire Pump. I didn't see the purpose for the CT cabinet,with individual self contained meters, either. Probably should've calculated the service, & installed a main Disc. but in My location, the POCO won't allow a Disc. before their meters, this is more than likely how this evolved. I believe I would've tried to get the building Owner to install a main disc, CT metered, & individually metered the 10, or added an estimated cost to the rent, & included it.
You cant do that here! From SoCA Edison's Service requirements:
"A main disconnect shall be installed on the line side of a group of more than six meter sockets, safety socket boxes, instrument transformer boxes or switchboards. A main disconnect shall be installed on the line side of groups of two to six meter sockets, safety socket boxes, instrument transformer boxes or switchboards where groups of switches, circuit breakers, or disconnects that constitute the meter switch, and the total number of switches or disconnects exceeds six.2/ The main disconnect may be a fused switch, or a circuit breaker. Where fuses are installed, the Company is not responsible for their replacement. Main disconnect enclosures containing unmetered conductors shall be sealable"
