The holes on the back are there for quick wiring. You strip the wire and then insert it into the holes. It is held in place by spring tension. I do not recommend you wire the outlet by using these holes. From my experience the wires are not secure enough. Strip the wire and wrap it around the screws and tighten it securely which is what all the good electricians I know do. Takes a little longer but IMO it is more secure.
In a standard wall receptacle, the third prong is for a safety ground wire.
No, except that you insert the wires into the holes on the back of the outlet. The power in connects to the LINE side of the outlet and power out connects to the LOAD side of the outlet. This is clearly marked on the back of the outlet. This will not only protect the outlet with the GFCI installed but all outlets receiving their power from that GFCI. If you do not want to protect the outlets receiving power from the outlet then connect that outgoing wire to the LINE side also. But know that only the outlet with the GFCI will be protected and all other outlets will not be GFCI protected.
A 15 amp 125 volt outlet is a household outlet.
You are probably measuring between the one leg of the 240 volts and the neutral or the ground pin connection. Take the measurement from the two outside blade holes on the receptacle. There the reading should be 230 to 240 volts. Between either of the outside blade holes and the neutral or ground you should read around 120 volts.
Because it has electricity flowing to the outlet.
Ground wire is loose or disconnected somewhere in that circuit.
If it's an outlet that's round with many holes it is probably the drain in the sink.
Do that
opening, outlet
If you are using proper authorised outlet boxes, they come with all the holes pre-cut. Holes to mount wire clamps and holes for mounting screws. If you don't use these you are not 'to code'
Simply put, it is any electrical outlet the has three holes that the female end plugs into. What this is referred to most of the time (but not always) is a regular 110V outlet. Older outlets had only two holes, one for the hot, one for the neutral. All newer installations have the third hole for the ground wire.
Anything that is grounded. Something like you walk outlet. There are three holes in an outlet with various shapes depending on where you live. But one of the holes is for a grounding prong. You should make sure you know which one is the ground before sticking it into the outlet though.
You need to find an adapter.
Inside the "holes" are springy brass fingers that grip the plug prongs when you insert the wall plug, making connection with your home's electrical system.

No, it is a normal two prong fuse. There are three holes in the fuse box because if you put the fuse to one side the outlet is battery powered and ignition powered on the other.No, it is a normal two prong fuse.

What's the question? The holes on the back of the outlet are for inserting the wire and to release it so you can pull the wire back out. There should be a round and a rectangle one for each side terminal. They only accept 14 gauge wire, not 12 gauge. Older one would accept both, but not for several years. Wire goes in the round hole and you insert something such as a small nail in the release hole and push in and then pull the wire out. The outlet will have a strip gauge on the back if the holes are for self holding lugs, and a square or round release next to the hole. You don't have to hit the release when inserting wire,only removing it. If the outlet is rated 120v, 15 or20 amp,it will hold 12ga wire.
The "hot" side of the receptacle is the smaller of the two blade holes. It is on the right with the U ground facing down.
