To tell it from the black wire. Just a standard in residential wiring.
If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.
The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
Black Wire from photocel to hot wire(black) coming in red wire to light fixtures black wire. White wire to neutral wires all light and power source white.
Red is hot, black is not.
black to black
ground wires are always black, the trigger is pink
Green is generally the ground wire and black is almost always the hot wire. It is usually not a good idea to hook them together. Without knowing what each wire does, there is no way to tell from here.
You always switch the HOT side of the light, never the neutral. This would be the black wire from your voltage source.
Remove the old single pole switch. Connect the green dimmer wire to the ground wire. Now connect the black dimmer wire to the black wire that is the hot wire (wire carrying the electrical current into the box). Connect the red dimmer wire to the other black wire.
Red wire is positive (+) and black wire is negative (-).
Red wire=positive Black wire=negative
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
no sparking fanThe white wire from the fan to the white wire from the ceiling get wire nutted together.The black and blue wire from the fan go to the black wire from the ceiling and all 3 get wire nutted together. Lastly the green wire from the fan and the bare copper wire from the ceiling get wire nutted together. 90% of fans are wired this way.
It depends on the color coding standards for what country you are in. In the US, the answer is no. The Neutral (white wire) is grounded at the service entrance to the building. The black wire should have roughly the same voltage to the neutral and to the ground. Something to be aware of: If you are using a meter and checking for continuity between the black wire and ground, it may tell you that they have continuity if the breaker is on.
Bring the hot power wire into the wall switch box and run another wire out to the outlet. Tie all the whites together in the switch box under a wire nut and shove this back into the box. Tie the black incoming wire and the black wire going to the outlet together and jump a wire off this to one of the screws on the light switch. Connect the black wire going to the light to the other screw on the light switch. Connect the white/black wire to the outlet.
Run a wire from the light to the switch. At the light connect the black power wire to the black wire to the switch. Not wrap some black electric tape at each end of the white wire going to the switch (This indicates that the wire is potentially hot and not a common wire). At the switch connect the black wire to one side of the switch and the taped wire to the other side of the switch. Connect the ground (bare) wire to the green screw on the switch. Now at the light connect the taped white wire to the black wire feeding the light and connect all grounds together with a wirenut.
It really does not matter which wire you use, the important thing is to make sure you user the same polarity throughout all of the system connections. General consensus is to use the black wire to all of the negative terminals.
The black one
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).
Battery wire is always the biggest wire of all.. It's either red or Blue/black for positive and the black for negative.. hope this helps..
That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.
i can tell you which one it's not and that is the black with white stripe that one is a ground.hope this helps at all.
