How do you hook up a light fixture to a switch?
Hang the fixture temporarily (without mounting) and make contact between one wire from the fixture and the live wire (the black one) coming from the switch. In the same way, join another black wire to the white electric wire.
How to set up two ground wires on a light fixture?
To set up two ground wires on a light fixture, start by connecting the first ground wire to the green ground screw. Now use a connector to link both ground wires to each other. This will create a perfect circuit that allows the current to go through safely. Each light fixture is different and the layout is going to vary.
How do you wire a light fixture to a black wire?
Twist the ends of the two light fixture lead wires together. 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.
Are there extra wires when installing a light fixture?
These extra wires may create some confusion if you have never installed a light fixture before, especially since, under normal conditions, a single black hot wire exists in the electrical box. Knowing how to connect these lead wires will simplify the light fixture installation.
Why would there be two hot wires?
The reason for multiple hot/neutral wires for one outlet is that the outlets are daisy-chained together. This means hot/neutral is only coming from one of the wires and it is being sent to the other wire.
Can you wire two hot wires together?
Nothing. Two hots of same circuit - nothing should happen.
How do you install a light fixture with two lead 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.
Why are both black and white wires hot?
Here's a rundown of electrical wires: 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.
What happens when two hot wires touch?
A short circuit happens when a “hot” wire (black) touches another hot wire or touches a “neutral” wire (white) in one of your outlets. When these two wires touch, a large amount of current flows, creating more heat than the circuit can handle, so it shuts off.
Can 2 hot wires share a neutral?
What is a multiwire branch circuit? A multiwire branch circuit is a branch circuit with a shared neutral. This means there are two or more ungrounded (hot) phase or system conductors with a voltage between them and a shared neutral.
Why do I have 2 black and 2 white wires?
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.
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.
Can I connect red and black wires 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.
Why are there 2 black wires on light switch?
Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires. It's essential that you determine which black wire is hot before proceeding.
What happens if light fixture is wired wrong?
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.

Understanding Light Fixture Wire Colors
Normally, light fixtures feature different color wires that match the wires in the electrical box in the ceiling. This makes replacing an existing fixture with a new one reasonably easy–until you realize your fixture has two black wires.
Wiring A Light Fixture With Two Black Wires
If both black wires are smooth, or you just want to make doubly sure (good practice), you can test the fixture. This is a good idea before going through the trouble of replacing the fixture and installing it completely. You don’t want to get the whole project done only to learn you need to undo it to switch the wires.
When Should You Call An Electrician?
Normally, when installing a simple light fixture on one light switch, it’s pretty straightforward. But, sometimes, it can prove to be more difficult than first expected.
Frequently Asked Questions
Not including the price of the fixture, you could pay between $75 and $115 for an electrician to swap out a light fixture. This is as long as there are no unexpected problems or issues. To install a new light fixture with electrical, it could cost closer to $300 to $400.
How To Set Up Two Ground Wires On A Light Fixture
When figuring out what to do with ground wire on the light fixture, it’s important to uncover it first.
Final Thoughts
These are the steps to follow if you want to have two ground wires on a light fixture.
Pliers
You will need the pliers to secure the wire connections. This action prevents the failure of the fixture and fire hazard. Twist the wires to make the connections tight. In addition, this tool also allows the formation of neat connections when you cut the wires and eliminate the protruded parts.
Screwdriver
Any installation involving wires needs a screwdriver, the main function of which is to tighten the screws and hold them in their positions. Like pliers, this material is necessary for making better connections that are long-lasting. Some screwdrivers come with an interchangeable tip or head, making them versatile for both smaller and larger screws.
Voltage Tester
Several good-quality non-contact voltage testers are available in the market. Their purpose is to test that the device is not drawing any voltage during its adjustment and fitting process. Moreover, they also facilitate providing information about the neutral and hot wires.
Multimeter and Voltmeter
The function of both the voltmeter and multimeter is to analyze the circuits and the voltage. The information is displayed on a screen, after which a person can fix the product. A multimeter provides the data regarding various characteristics, including resistance, polarity, and voltage.
Wire Nuts
You will need the wire nuts or twist-on-connectors for securing the electric connections through which less voltage is flowing. They allow you to fasten these connections that provide insulation. Other terms for this tool are thimble connectors and cone connectors. Generally, orange nuts are common when dealing with light or fan fixtures.
Striper
As their name suggests, the strippers are needed to remove the wire sheaths. It will expose the copper inside to form connections with other wires. The blades on these tools make it convenient to remove the skin of cables. They are also beneficial for repairing the cables as well as replacing them.
