The heart of the system. 

Unlike other pre-packaged systems, Generac includes an automatic transfer switch (standard equipment with all models). 

This device will ensure your vital electrical loads are powered, even when you are not there. 

This transfer switch is the difference between a truly automatic generator set and just another generator. 

No toggles to flip, no knobs to turn, no extension cords to run when you lose utility power. 

You will have the comfort and peace-of-mind knowing that your Guardian emergency power system does everything for you... automatically.
