To attach a ground when you have two wires, first identify the ground wire, which is typically green or bare copper. Connect the ground wire to the grounding point (like a grounding screw or terminal) in your device or electrical box. Then, securely connect the two other wires (usually the live and neutral wires) to their respective terminals. Ensure all connections are tight and insulated to prevent any electrical hazards.
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.
attach wires to a person's head.
you get a loc (line out converter) it'll have 5 wires 2 neg 2 pos and 1 ground attach the speaker wires to you two rear speaker how you do this is up to you and then hook up the ground to something metal get some rca wires plug em in and boom your all set up now all you need are amps and subs
In a box it is common practice to join two black wires, two white wires and two ground wires, for example, to extend the circuit to another location. Provided you don't overload the circuit it is okay to put 3-wires into the comparable wirenuts for your external light. There are some added caveats including not exceeding the number of wires designed for the box (usually 4); and outside circuits normally require a GFCI circuit for safety.

With one interpretation of this question, the answer would be two 120V wires and a ground.

There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.
You should attach one end of each wire wire first to the track where the two recivers for the wires are, and then hook the other ends of the wires to the power pack. *MAKE SURE POWER PACK IS OFF BEFORE ATTACHING ANY WIRES* After you have attached the wires you can turn on or plug in the power pack and run your model trains.
There is a good chance that the green wire is your grounding wire. http://www.youtube.com/watch?v=KNo78fMZfRI&feature=PlayList&p=05D94AD4BF05DD32&index=5&playnext=4&playnext_from=PL Attach black to black with connectors and ground (green) to ground (usually a white wire in the box).
