The setup is
Generac 300A Service rated with disconnect that will feed 2x 200A Main breakers panels in the basement (I like to have main breakers so I can shut them off even though I can use sub panels without main breaker, the price is the same for both)
The ATS only allows 1 conductors on the T1/T2 load side but I need to hit two panels.
I think the best way is using tap rules.
I am not exactly sure how the 83% rule would apply to this and if the rule carriers on through the taps. Since it is 300A ATS I would use 250 KCM Copper from 75 degree column and tap two 2/0 copper conductors (1 for each panel) from the 250 KCM.
Would this work?
