Does the red wire need to be connected?
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 to do if there is no red wire?

- Always-hot (preferred: black, any color other than white gray green is legal)
- Switched-hot (preferred: red, ditto)
Why do I have a red wire in my light fixture?
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.
Where do you connect the red wire in a junction box?
When the switch is on, the black and red wires are effectively connected together at the switch, so the voltage between them is zero. If you look inside the box where the switch is, you’ll see that it is connected between the black and red wires.
Do black and red wires go together?
These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.
Can red and white wires go 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.
How do you add a neutral wire to a switch box?
Quote from the video:
Quote from Youtube video: Find that neutral wire which will be on the other side of wherever the load wire is and you could run that wire back down into the light switch and now you have a neutral wire.
Do I need the red wire for ceiling fan?
Wiring a Fan With a Switch for Light and Pull Chain for Fan
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.
Why doesn’t my light switch have a neutral wire?
Switches don’t get neutrals, they only want 2 wires: hot and switched-hot. Unless you’re dealing with a smartswitch, those take neutrals but there is still a switched hot to account for. And red is a common switched-hot color, but it would never, ever, ever, ever be used for neutral. Ever.
What is the red wire in a ceiling junction box?
A red wire up in the ceiling fan junction box usually indicates that the wiring has been installed which provides separate switch for the light and a separate switch for the fan motor. If your ceiling fan does not have a light fixture, then simply cap off the red wire and attach the fan motor to the black wire.
Are red and black wires the same?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.
Can red wire be ground?
Standard House Wiring Colors
In the standard wire color code, the hot wire in a cable with two conductors plus ground is black, and the extra hot wire in a three-conductor set is red. The standard ground wire color is either bare copper or green.
Can a red wire be neutral?
You CANNOT use a red wire for a neutral.
Where do the red and black wires go on a light switch?
Basic Knowledge of How to Wire a Light Switch
- Black Wire – This is the hot or load wire.
- White Wire – This is the neutral wire.
- Bare Copper (Green) Wire – This is your ground wire.
- Red Wire – This wire is used for 3 or 4 way switches and will connect the switches together so they can each control your lights.
How do you connect a red wire to a light switch?
It doesn’t matter which traveler wire (red or black) connects to which traveler terminal as long as it’s the same in both switch boxes. For example, if the red traveler wire is on the top traveler terminal in the first box, it should also be on the top traveler terminal in the second box.
Does red wire go on top or bottom of 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.
How do you wire a red wire?
