If the red and black wires are connected together already and energized, yes you can do that but you will need a pull chain light or a remote control, if they are not switch controlled.
Likewise, What colors are electric wires?
What the Color of an Electrical Wire Means
- Black Electrical Wires. This color of wire is used to transfer power to switches and outlets in all types of circuits. …
- Red Electrical Wires. …
- Blue and Yellow Electrical Wires. …
- White and Gray Electrical Wires. …
- Green Electrical Wires.
Also, What do I connect the red wire to?
Normally you’ll see a red wire in places you would expect a ceiling fan. But in places like a bathroom or a wall light, if you see a red wire, it’s a good bet that the red wire is the wire that’s connected to the light switch.
Moreover, Can I connect white and black wires together?
If you see both sides connected together, it means it’s a switch loop. The white wire that’s connected to the black wire carries power to the switch. And the black wire that’s in the same cable carries back that switched power to the outlet.
Where does red wire go on 3 way switch?
The black hot wire connects to the far right switch’s common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch’s common terminal, leads back to the fixture.
Are white wires positive or negative?
The black wire is positive, the white wire is negative, and the green wire is the ground.
What is red black and white electrical wires?
According to standards in use since the mid-1900s, a wire color code identifies the purpose of each wire in an electrical circuit. The white wire is always neutral, and when the cable has only two conductors, as most 120-volt cables do, the hot wire is black. … The red wire is for the light switch.
Is yellow wire positive or negative?
Yellow is positive, blue is negative.
Where does red wire go on light fixture?
Attach the red wire from the light fixture to the nut at the top left of the switch. Connect the bare copper wire to the green nut at the bottom left of the switch. Push both switches into their boxes and secure them with screws at top and bottom. Turn on your power and test the switches.
Can I connect red and white wires together?
In the US, the answer would be no, even though I am reluctant to answer this. White is not aggressive. White is neutral, black is 120, green is ground, and red is the other phase of the mains into your house.
Are red wires positive or negative?
The coloring is as follows: Positive – The wire for the positive current is red. Negative – The wire for the negative current is black. Ground – The ground wire (if present) will be white or grey.
Why do I have 2 black wires and 2 white wires?
the black and white wires from the power supply side need to be attached to the line side of the new outlet. (it should say this on the back of the new outlet) and the other 2 are to be attached to the Load side of the outlet.
Why do I have 2 black and 2 white wires?
Each lightbulb socket must have a separate black and white wire to supply electricity to the lightbulb; the more lightbulbs, the more wires. … Connect the two black wires from the light fixture to the black wire from the electrical box the same way you connected the white wires.
What happens if you connect the wrong wires on a light fixture?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
Where does the red wire go?
Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.
What color wires go on a 3-way switch?
There is no standard for wire colors on 3-way switch travelers. The colors will vary depending on whether NM cable or conduit was used. With NM cable, the wire colors for travelers will be black and red using 3-wire cable. With conduit, the wire colors for travelers could be any color.
Where does the red wire go on a light switch?
Attach the red wire from the light fixture to the nut at the top left of the switch. Connect the bare copper wire to the green nut at the bottom left of the switch. Push both switches into their boxes and secure them with screws at top and bottom. Turn on your power and test the switches.
What happens if you connect a positive wire to a negative wire?
If you connect positive to negative directly with a wire, you get a very low resistance circuit. The lower the resistance, the higher the current. The is called a short circuit.
What is the white wire in electrical?
Electrical Wires
The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel. The plain (or it can sometimes be green) wire is the “ground” wire, which will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
Is solid wire positive or negative?
The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the “wall wart” power supplies. Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end.
Where do I connect the red wire on a light fixture?
Attach the red wire from the light fixture to the nut at the top left of the switch. Connect the bare copper wire to the green nut at the bottom left of the switch. Push both switches into their boxes and secure them with screws at top and bottom. Turn on your power and test the switches.
Is a red wire positive or negative?
The coloring is as follows: Positive – The wire for the positive current is red. Negative – The wire for the negative current is black. Ground – The ground wire (if present) will be white or grey.
Where do you connect the yellow wire?
Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches.
Is orange wire positive or negative?
Always assume that a red or orange wire (in addition to the black wire, which provides the primary phase voltage) is live. Also Know, is blue wire positive or negative? Blue is Negative, and White is Positive. Orange Sheathing The orange-colored wire sheathing is set aside for 10-gauge wire.
