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 do the colors of wire mean?
Blue and yellow wires are sometimes used as hot wires and as travelers, green wires (and bare copper wires) are ground wires, and white and gray wires are neutral. However, all electrical wires, regardless of their function, may carry an electrical current at some point and should be treated with equal caution.
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.
What happens if you switch black and red wires?
If you switched the wires, what would happen? Red is positive charge, black is negative charge. If you aren’t running if you aren’t connected correctly.
What is L and N in electricity?
The N & L stand for Neutral and Load. With your AC line in you should have three wires. Neutral, Load, and Ground. If your wires are color coded for the US then the black wire is Load or Hot, the white wire is Neutral, and the green wire is Ground.
Which Colour wire is live?
The live wire is brown in new systems and red in old systems. The neutral wire is blue in new systems and black in old systems.
What color is common wire?
The White is often referred to as Common, but the colored wires are also used as hot wires.
Where do I connect the red wire for a light?
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.
Where does red wire go on ceiling light?
Connect the red wire in the ceiling to the black wire in the light kit and the black wire in the ceiling to the black wire in the fan. Tuck the wires back into the box.
What does a red wire mean in a light fixture?
The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire. … If turning the switch off turns the wire off, the red wire delivers power from the light switch. Note: Never touch wires or their connection points while the circuit is energized.
Can a neutral wire be connected to a hot wire?
You can have multiple separate loads between the hot and the neutral. Each of them is connected to the hot side and the neutral side. When no device is working (drawing power), no current flows. There is never a direct connection between the hot and the neutral wires.
Why do I have 2 black 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.
Do I Connect the black or white wire first?
When electrical wires are joined together the black wires must be hooked together, the white wires must be hooked to the white wires, and the ground wires must be hooked together. Otherwise, the circuit will not work, and will result in an electrical “short.”
Which wire is positive when both are black?
If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive. Look in the owner manual to determine which wires are negative in a car.
Is the black 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.
What is the difference between red and black electrical wires?
In Oz red is used for positive on DC and the Active (or hot as some like to call it) wire on AC. Black is used for negative on DC systems or the neutral wire on AC systems. Green or green and yellow is reserved for earth.
What is L and N reverse?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is.
Which Colour wire is L and N?
US AC power circuit wiring color codes
| Function | label | Color, common |
|---|---|---|
| Protective ground | PG | bare, green, or green-yellow |
| Neutral | N | white |
| Line, single phase | L | black or red (2nd hot) |
| Line, 3-phase | L1 | black |
Is L positive or negative?
There is no ‘positive’ or ‘negative’ terminals in AC but Line or Phase (L) or (P) and Neutral (N).
What does Blue wire mean?
Blue wire generally refers to a type of wire or cable that is added to a hardware product at a factory in order to resolve design problems. Blue wires are also known as bodge wires in British English.
Which wire is live?
Wiring Colour Codes
The blue wire, also referred to as the neutral wire, has the function of transferring electricity away from the appliance. The brown wire, otherwise known as the live wire, transfers electricity to the appliance. The combination of these wires is referred to as a circuit.
Is black wire positive and red negative?
One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.
