“Can this be hung from a 30 inch upper cabinet over a counter top? I need to hang this from a top cabinet over a counter space. Can this be installed this way? What is underneath the microvave as I do not have a shelf and it will be exposed although low enough that it can't be seen. It is a 30" cabinet so I am assuming I need the 30 inch trim kit, is this correct. Does the picture show the trim kit (is it the outer edge of the microwave in the picture)?”
