Electric Cook-top OUTSIDE?! Is it rated for wet/damp locations? I cant see the patio from here, but sounds like it is exposed to the elements, even if morning dew, if not blowing rain. Sounds like an electrified rust activated time bomb. GFI it, or disconnect it, I might opt for the latter. But short of that, a GFI is not a bad idea. I cant think of a requirement to do so....
