From the 1996 NEC:
230-71. Maximum Number of Disconnects
(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...
