In my kitchen under my sink I found an outlet that didn't seem to work until I realized it was controlled by a switch up next to the window.I am assuming... it is for a garbabe disposal. At some point someone put in a single outlet [round kind]. Anyway, is this outlet supposed to be GFCI, which it isn't. And, just out of curiosity can a GFCI adaptor be used, it's not like it's on all that often?
