Existing 400Amp panel, Main Lug 3P, 120-208vOLT with a High Leg, Total of breakers in panel is 2-150Amp 2Pole, and 4-200Amp 3Pole breakers in it. Is it legal or does it have to have a means of a disconnect??? Feed from CT Cabinet located 10' away. All breakers are Controlling Sub Panels thru out a warehouse and None of them have any Main breakers as well..
 
Sounds like a service panel if the only thing ahead of it is a CT, and as far as the number of breakers, it is legal (230.71--6 disconnect rule).
The breakers in this panel can serve as the mains for the panels they feed.
The 120/208 panel on a 240 hi-leg service, however, is probably not to Code.

120/240v with a 208v high leg, actually.

Legal, with the usual based-on-your-description disclaimer.

None needed within the same building.
 
If the system is in fact a 240/120 Hi-Leg Delta, you need to look at 240.85 in regard to all the panels/breakers.
