Some light fixtures do not have a grounding wire. In such cases the two wire going to the light may both be black. You can connect black supply to either black light wire and white supply to the other black wire.

If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.


If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?

If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.


How do you correctly wire a switch to a bathroom fan light combo you have 1 w b g coming from your breaker box you also have 2 w b g wires one that controls the fan and one that controls the light?

Tie all White wires together. Tie the Grounds together and connect them to the ground screw on two switches. Create a pigtail with TWO black wires coming out. Connect a black wire to each of the two switches. (you pick which screw, but be consistent. Connect the black wire from the light to the remaining screw on one of the switches. Connect the black wire from the fan to the remaining screw on the OTHER switch.


When wiring a light fixture does black go black and white on white?

If these are all the wires you have then this would be a great assumption. It assumes also that everything before the fixture is wired correctly and with commonly used color schemes.


What if the light fixture has two copper house wires?

If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.

Do you attach the red wire to the brown and black to the blue for a light?

No, typically red wires are connected to hot/live wires and black wires are connected to neutral wires. Blue wires are often used for connecting to neutral wires as well. Remember to always follow the wiring instructions provided with your specific light fixture.


How do I properly connect two black wires on a light switch?

To properly connect two black wires on a light switch, you should twist the exposed ends of the wires together and secure them with a wire nut. Then, attach the twisted wires to the black screw terminal on the light switch and tighten the screw to secure the connection. Make sure the wires are properly insulated and the switch is turned off before making the connection.


If there are two black and one white wire in ceiling light do I need to use both black for the switch to work?

If there are two black wires, it's possible that it was wired for a ceiling fan and that one of the wires is for the fan part while the other is for the light part. If so, one of the black wires may be switched while the other is always "on." Normally black is "hot" and white is "neutral" (NOT ground... ground is usually green).

Why would a light switch have two black wires for power and two whites caped off?

Black represents Hot and White common. For the light to operate it needs a white and black wires. The switch box has two cables with a white and black wire plus a ground. One wire is from the supply and the other to the light. Connecting the whites just provides common directly to the light. The blacks go into and out of switch because it is the hot side that is being switched.


Can you run power from a light fixture to another light fixture?

Yes. Connect Black to Black, White to White and bare ground wires together.

How can I wire a ceiling fan with a light switch using a diagram?

To wire a ceiling fan with a light switch, follow these steps: Turn off the power to the circuit at the breaker box. Install the ceiling fan bracket to the ceiling. Connect the fan wires to the corresponding wires in the ceiling box (usually black to black, white to white, and green to ground). Connect the light kit wires to the corresponding wires in the ceiling box (usually blue to black and white to white). Install the fan blades and light kit. Install the light switch and connect the wires (usually black to black, white to white, and ground to ground). Turn the power back on and test the fan and light switch. For a visual guide, refer to the diagram below: Diagram of ceiling fan wiring with light switch
