Greg,

Good Morning! I don't know how much they are selling for, but the HO wants to install this item himself. It will be his responsibility ( and he knows this) too make sure that he doesn't overload his gen. when he hooks it up. However he feels that he will save a lot of expense by not installing a transfer switch and full size stand by gen. He will use a small portable gen, with and outside receptacle to plug his portable gen into and back feed his panel.
