I just received my order from Elec-tra-mate of the Hubbell 15 amp mounting kit and am trying to figure the best way to mount it. I woul dlike to mount it flush, but I am not sure that is doable with the box. I have installed regual outlets in my house, so the elctricity is not a problem. Just trying to figure out how to install it flush. Do I use the box? How big of a cut? Has anyone installed one of these. I will likely call Elec-tra-mate on mOnday, but trying to figure it out before then to mount it.
