No. You can split the hot feeds and you can split the neutral feed, but both outlets of a standard duplex receptacle share the ground.
You use a known ground and check them for voltage. You can use an extension cord to reach from a ground to the wires you are testing. You are not putting it in an outlet, just to connect you to a ground.
In a 220V outlet, the neutral wire is typically not used. Instead, you will have two hot wires and a ground wire. The two hot wires carry the voltage to the appliance or device, while the ground wire provides a path for any stray current to safely dissipate.
The normal colors of a residential outlet are black(hot), white(nuetral), and bare/green(ground). It is common to 'feed thru' an outlet, in other words to bring the power in on one trio of wires tied to the outlet and send it out on another trio of wires also tied to the outlet. If however one white wire is not connected the power will not feed thru properly and whatever outlets are downstream will not work. It is possible to burn up whatever equipment is plugged into the downstream outlets, espiecaly if it is electronic ie; omputers, video equipment etc... Hope this helps. Remember turn off power before working all electrical outlets.
In a 220 volt outlet, the red and black wires are typically connected to the two hot terminals of the outlet. The white wire is connected to the neutral terminal and the green or bare wire is connected to the ground terminal. It's important to consult a professional electrician to ensure proper installation.
The ground wires are twisted together and then connected to the GFCI ground. The black and white wires may also be twisted together and then using a jumper wire connected to the GFCI. Hard to say without seeing exactly how it is wired.
Yes, all receptacles require an earth ground. (the bare copper wire in house wiring). However, it is not a dedicated ground in that all ground wires in a houses electrical system are connected or in common.
An outlet can be properly grounded with only 2 wires by using a Ground Fault Circuit Interrupter (GFCI) outlet. The GFCI outlet can provide ground fault protection even without a separate grounding wire.
the bare copper is always a ground
Hot, neutral and ground.
The standard outlet wiring colors used in electrical installations are black for hot wires, white for neutral wires, and green or bare copper for ground wires.

To hook up a GFCI outlet, first turn off the power to the circuit. Remove the old outlet and disconnect the wires. Connect the line wires to the line terminals on the GFCI outlet and the load wires to the load terminals. Make sure to connect the ground wire as well. Secure the outlet in place and turn the power back on to test the outlet.
To replace a wall socket, first turn off the power to the outlet at the circuit breaker. Remove the cover plate and unscrew the outlet from the electrical box. Disconnect the wires from the old outlet and connect them to the new outlet in the same configuration. Screw the new outlet into the electrical box and replace the cover plate. Turn the power back on and test the outlet to ensure it is working properly.
If the wiring system into which you are installing an outlet has no ground available, use an ungrounded outlet. In an ungrounded system, an outlet with a ground contact would allow the outlet user to mistakenly, and perhaps dangerously, assume that a ground was present. A suitable ground may be available as a ground wire accompanying the hot and neutral wires in the cable, or a ground may be available via conductive conduit and a metal outlet box. In any case, use a tester to confirm the integrity of the assumed ground. A voltage test from the hot wire to the ground should show the same voltage as between hot and neutral (the black and white wires respectively). If you are replacing an ungrounded outlet, you need not assume there is no ground present. You may find, in the box, ground wires that were not connected to the outlet. You may come across grounded outlets that have no ground wire attached because they rely on grounding via the mounting screws through the outlet ears to the metal box. This is a less reliable grounding method. It is better to buy a ground-wire "pigtail," fasten the wire directly to a hole in the metal box with the supplied screw, and attach the other end of the ground wire to the outlet via the outlet's ground screw.
To replace a wall socket, first turn off the power to the outlet at the circuit breaker. Remove the cover plate and unscrew the outlet from the electrical box. Disconnect the wires from the old outlet and connect them to the new outlet, following the same configuration. Secure the new outlet in place and replace the cover plate. Turn the power back on and test the outlet to ensure it is working properly.
In a 220V outlet, the neutral wire is typically not used. Instead, you will have two hot wires and a ground wire. The two hot wires carry the voltage to the appliance or device, while the ground wire provides a path for any stray current to safely dissipate.
To wire a double outlet, you will need to connect the black wires to the brass screws, the white wires to the silver screws, and the ground wires to the green screw. Make sure to turn off the power before starting and follow the manufacturer's instructions carefully.
