Context: Rental house built to US/Oregon code in 2008.
There's a receptacle in my kitchen covered by a blank plate. It's located vertically below the lip of my counter. When I opened it, it had one bundle of wires. Hot and neutral were both capped, and a no-contact tester told me the wires were hot. My intuition says that the home builders were going to install an outlet here before something stopped them.
Is there any reason I can't/shouldn't just pop a GFCI into the receptacle and call it good? Like e.g since the height of the outlet is below the level of the counter, water that gets on devices' cords will flow into the outlet
