I should have noted in my previous answer to this question that many zoning laws require that certain residential and commercial areas should use more expensive (and, arguably, more difficult to install) GFCI outlets instead of standard electrical outlets, such as this one. For the most part, GFCIs should be used wherever water is present, such as sinks, boilers, water heaters, baths, washing machines, but, there are some folks who put them everywhere (FWIW, in one instance, I had to use a GFCI instead of a standard outlet, because both ground wires had broken off inside the outlet receptacle/box, and there was no way to fish out the rest, never mind that there was no extra length to stretch out, so I couldn't even pigtail off the rest; GFCI's don't need ground wires, because they have built-in circuit breakers; however, they do not last as long as standard outlets, needing to be replaced every ten years or so, which is expensive and annoying! When I need the house wiring upgraded, I will have that outlet's wiring replaced, professionally. For that GFCI-replaced outlet, I covered the ground (half-circle) hole, so that only 2-prong electrical cords can be used, and I put a "NO EQUIPMENT GROUND" label (which comes with all GFCIs in a sheet, along with "GFCI-protected" labels, et al.) over the face plate as an additional warning).
