New house 300 amp underground service, just installed all the slab and underground conduits today.
My question is , the HO is supplying a 20 kw Generac and two ATS, the ATS comes with a 200 amp breaker.
I know for a while they used Murray main breakers. I need to either swap out the mains to 150s or install 150 amp MB panels and 2/0 cu .
Does anyone know the brand main breakers used in Generac 200 amp ATSs?
I prefer main lug panels.

Generac makes 150 amp. ATS if it is not too late...

Just curious as to why you'd waste time, money and effort on a 300A service when a 320/400A is almost the same price?

A 400a service here needs a CT cabinet type meter pan.. LIPA wont allow it any other way...

That sucks.

That sucks.

Yup.. the meter pan is more than twice the size..

Doc.. not sure if you know this.. but when you have (2) ATS.. you need to jump wires 23.. 194.. and 0 from main ATS to slave unit...

I don't understand your question. I have a 15 kva xfmr feeding my 200 amp panel here in 15330.

LIPA does not allow 400 amps from a 320 pan, they require a 400 trans s cabinet. The house could have gotten away with a 200 amp but bcause I know the HO and wired his former home, I expect an IG pool, hot tub, and many more things to be added down the line.

Thank you B, I did forget that. The last time I did twin units was in 05'.
