I Would Recommend And Again I Wouldn't?
By Timothy D 
New York
Purchased 03/25/2024 | 
Review Posted 05/07/2024 
Not enough room to work with anything bigger than 4 /0. Neutral lug connections are not sized properly. Needed to alter ground bars and neutral. If you need this panel because you need power supply outside then I would recommend. But it needs to have ample room for entry and better neutral lug connections.

This panel is built with better quality control than the regular ATS and has ample space to accommodate different wiring methods.

Our Second Generac
By Gregg H 
Maryland
Review Posted 10/28/2022 
Have an older Generac model for our residence. Bought a second this year for a second property we own. Has great updated features and is much quieter. Next year we may think about updating the one on our main house.

The Cadillac Of Transfer Switches
By Jason V.

200 amp main service disconnect with automatic transfer switch and built in main panel. The chassis is well constructed and the internal components are rigidly mounted. The unit is quite large and heavy so make sure you have a good mounting point. You'll need to have the correct size hole saw for your conduit terminations as this unit has no preformed knockouts. Having a main panel on the exterior of the home is really nice for people with property to run power to well pumps, garages and outbuildings without having to enter the home in conduit. Internal control electronics in the unit are there ready to connect the smart load shedding/control modules if you need them based on your connected load size and generator capacity.

Easy To Hook Up But Not Happy
By Steve S.

Purchased 10/07/2020 | 
Review Posted 03/12/2021 
I think I waited for months for this product it wasn’t inspected properly I had problems with it I had to send out one of your Generac dealers to fix it I wasn’t compensated and the generator that came with it was missing parts I guess you could fill out the review survey for yourself
