Why does my ceiling fan have 4 wires?
In order for the light to be controlled by its own switch, the wiring between the switch and the fan unit needs a fourth wire, a red wire, to carry power to the light kit.
What do I do with the red wire when installing a ceiling fan with remote?
The red wire is the ungrounded (hot wire) conductor of one switch, while the black wire is the ungrounded (hot wire) conductor of the other switch. One switch would energize the red wire in the original installation, causing the fan to turn on. The other is responsible for the black wire to turn on the light.
How do you wire a light fixture with two wires?
Connect the lead wires from the fixture to the black hot wire in the electrical box by twisting a wire connector to the ends of the lead and hot wires. Repeat these connections with the two white neutral wires from the light fixture and the white neutral wire in the light fixture box.
Which wire is hot when both are same color?
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
How do you wire a ceiling light with a loop?

What are the 4 wires in a light fixture?
A four-wire electrical line has a red hot wire, a black hot wire, a white common wire and a ground wire. A two-wire line is usually a black hot wire and a white common wire. The ground may be there, but it may not be connected.
Why are there 2 black and 2 white wires in ceiling box?
So, why are there two black and two white wires in your outlet box? There are two black and two white wires in an outlet box because the outlet is in the middle of a series circuit, accepting power from another source and sending it on. Two cables are hot wires, bringing the power in and carrying it onward to the next.
What color wires go together for a ceiling fan?
Black wire is for the fan. Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground.
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.
When installing a light fixture which wire is hot?
The unmarked wire is the hot wire. Connect it to the colored (usually black or red) hot wire in the box. Complete the hook-up by looping the ground wire clockwise around the ground screw on the crossbar, tightening the screw, and connecting the end of the wire to the ground wire from the light fixture.
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. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
How do you know which wire is hot on old wiring?
The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
How can you tell which wire is hot and which is neutral?
Quote from the video:
Quote from Youtube video: The same applies to US and Canada outlets where the smaller. Slot is for the hot black wire and the larger one is for the neutral white wire.
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.
How do you know which wire is positive and negative on a light fixture?
Examine the wires. If they are made of opaque plastic and you feel a texture on one of them while the other is smooth, the textured side is neutral. You may see a stripe on one of the wires. If so, that wire is neutral.
What happens if you connect white wire to black 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 wire black and white backwards?
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. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off. Why is it dangerous?
How do you tell the black wire from the white wire?
Quote from the video:
Quote from Youtube video: So here we go again we want to see a hundred and twenty volts one wire the red lead going here black lead going to ground. And there you go that's the hot wire 120.
