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 color wires go together for a ceiling light?
Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground. Red wire is sometimes included and acts as a conductor to carry power to the light kit.
Also, 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.
Moreover, Which wire is always hot on a 3 way switch?
Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. It’s also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.
What are the white black and red wires?
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. This configuration, sometimes called a half-hot or split-tab outlet, is becoming increasingly popular, so it’s good to know how to wire it.
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.
Why does my light fixture have 3 wires?
The simple explanation is that a 2-wire system does not include a Neutral wire at the light switch, the 3-wire system does include the Neutral at the switch.
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.”
What color wire goes to the black screw on a 3-way switch?
The black wire from the circuit breaker panel gets attached to the black screw on the 3-way switch. The black and red wires from the white cable running between the switches get connected to either of the two brass screws on the switch.
What is the red wire in a 3-way switch?
Figure A: 3-Way Switch Wire Diagram — Power to Light Fixture
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.
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.
Why does my light switch have 3 black wires?
If the light turns on, the second black wire you connected to the switch is the switch feed and the unconnected black wire is the feed to the other loads. If the light doesn’t turn on, then it’s the other way around: the connected wire feeds the other loads and the disconnected wire is the light feed.
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.
What is the red wire in a 3 way switch?
Figure A: 3-Way Switch Wire Diagram — Power to Light Fixture
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.
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.
What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.
What happens if you wire a ceiling light backwards?
Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
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.
How do you wire a light with 3 wires?
- Connect all the bare ground wires together and nut them off. …
- Connect the incoming and outgoing white wires together with the white wire from your fixture and nut them off (very important the white wire to your switch is not in here)
- Connect the incoming and outgoing black wires AND the white wire from your switch.
What if there is no ground wire for a light fixture?
If by chance you are installing an electrical light fixture that has no ground wire into an electrical box with no ground wire as well, then simply connect together the hot wire from the electrical box to the hot (black or red) wire on the light fixture. … Make sure to use wire nuts to attach the wires together.
Can I connect 3 lights together?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
Do you ever connect black and white wires?
A single black and white connected together is normal. It is part of a switch loop. A black connected to a group of whites is not normal and probably should be connected to the other blacks. It is normal to have a white connected to a group of blacks if a switch loop is used.
What happens if I Connect the black wire to the white wire?
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 connect a hot wire to a neutral wire?
Tying together the hot and neutral wires creates a short circuit, which should immediately trip the circuit breaker.
