in a home no
in a car yes
In home wiring, hot wires are typically colored black or red, while ground wires are usually green or bare copper. In computer wiring, ground wires are typically black, while hot wires are often colored according to industry standards, such as red or yellow.
black wire is hot wire .And the white is the common or white is ground. Depends on what your talking about in an outlet or car battery. In a outlet the ground wire is green or bare copper. neutral is red and hot is black (I remember it by hot can kill you so black is death) if I am not mistaken. As for a car battery i think it's the opposite red is hot and black is neutral.
in back of dryer u should have a block with three wires 2 blacks 1 green the one u are trying to wire up should have 2 black 1 green 1 white the white and green wire go in the midle post of the block on the dryer and the other 2 wires go to the out side posts of the block
You will have to check to make sure. Normally, with 4 wires, the black and red are both power for 220. White for neutral and bare for ground. If you are only using one leg of it, you would use the black, white, bare ones and cap the red one. Someone may have used the 4 strand because they had it or 220 was planned but not done or both the red and black are hot. You should be able to tell in the panel. Do the red and black both connect to separate breakers or to one or is the red not connected?
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.
Ground wires are typically bare wire or green covered. Common wires are white and hot wires are black. If you have black wires that are grounds or commons you should contact an electrician to ensure you don't have a problem on your hands. Sounds like someone who didn't know what they were doing has been mucking around in your panel.
hot wires are black, white wires are ground
there is 2 wires one should be red to alarm and black to ground.

The green ground wire should be attached directly to the junction box. That is the metal housing where the house wires enter the outlet.

Answer There should be at least 4 to wires. Four of those wires are for your speakers, the other two, one red is for power and the black on for a ground
It is the black cable on the battery. All GM ground wires are black.
To properly connect two black wires on a light switch, you should twist the exposed ends of the wires together and secure them with a wire nut. Then, attach the twisted wires to the black screw terminal on the light switch and tighten the screw to secure the connection. Make sure the wires are properly insulated and the switch is turned off before making the connection.
Red= 12v Hot & Black is ground.
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).
