If you already have 120v pwr to the box you simply pigtail all conductors to wire as single.
This can not be done with the wire that you have. If you would like a detailed answer as to why not, start a discussion.
Hot wire (black) to the gold colored terminal, and neutral (white) to the silver colored terminal. On the front of the outlet, the wider prong is the neutral. You probably also have a ground terminal (green) to connect to the bare copper ground wire.
Connect the incoming power wire and the outgoing power wire going to the light switch to the line side of the GFCI outlet. This will protect the outlet and will not turn off power to the light if the GFCI trips.
A 120 volt duplex outlet is the main type of outlet for residential outlet system. The wires are typically white and black, and there should only be two of them.
You can use the wire rated for 20 amps on a 15 amp receptacle but you can not use a 20 amp fuse on any device rated at 15 amps. This is a tricky part of the code about receptacle outlets, You can use a 15 amp duplex outlet on a 20 amp circuit. (duplex outlet two devices can plug in) If it is a single outlet then the outlet must be rated 20 amp. NEC table210.21(B)(3). ============ A 15 amp duplex receptacle can be wired to a 20 amp rated circuit. This means the breaker OR fuse protecting the circuit can be rated 20 amps if the wire is also rated at 20 amps (12 AWG). --Sparkfighter
A duplex outlet is 115vac.
No, that is not unsafe.

Black, white, and copper.
Some rooms have an outlet controlled by a light switch at the door. This is normally in bedrooms. It is possible that the switch is wired to only one of two outlets in a duplex outlet since it is easy to configure a duplex outlet to separate the bottom and top outlets.
Duplex is Latin for "double". It literally means "twofold".
If there is a black wire going from the outlet to the switch and the other side of the switch goes back to the outlet then just cut these wires and connect supply wire directly to outlet. If the supply goes to the switch first, disconnect from switch and connect the two wires with a wire-nut. Some situations only switch one of the two outlets in a duplex device. Do the same thing, but also replace the outlet since the strapping between both outlets has been removed.
