You don't say "turn off" or turn on". Light should be connected black to black and white to white and ground to ground. If you connect white to ground it will work, but you are then using the ground wire for an unintended purpose. Neutral is bonded to Ground at the panel. Current on ground wire could cause ground loops and may cause GFCI to trip if you have them in your house.

This happens because the black wire carries the electrical current to power the light, while the white wire provides the return path for the current to flow back to the ground wire. When properly connected, this creates a complete circuit that allows electricity to power the light fixture.

How do you hook up outside light fixture that has black white green to house wiring with only black and white?

Connect the black wire from the light fixture to the black house wire, the white wire from the light fixture to the white house wire, and the green wire from the light fixture to the junction box ground wire or directly to the house's grounding system. Make sure to turn off the power before starting any work and follow all safety guidelines.


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).


Light switch has 4 wire colors red and white and green and black which is the hot wire?

You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.


Have 3 lights Power to light 1 Need to connect light 2 then light 3 then down to single pole switch How do you wire?

You can connect the three lights in series by running a connected wire from the power source to light 1, then another wire from light 1 to light 2, and finally a wire from light 2 to light 3. From light 3, run a wire down to the single pole switch to complete the circuit. Make sure to connect the neutral wires together at each light and the switch.

How do you install a swag kit with two wires to a light with three wires?

You will first need to determine which wire is the hot wire in the ceiling box. Connect the swag kit's two wires to the hot wire and the neutral wire in the ceiling box, leaving the third wire unconnected. Ensure all connections are secure and insulated. You may need to consult a professional electrician if you are unsure about the wiring.


Can white reflect black or does black absorb white?

White reflects light, including all colors, while black absorbs light, including all colors. This means that white does not reflect black, but rather all colors, and black absorbs light, even white light.


Does white or black absorb the light?

Black absorbs more light than white. White reflects most of the light that hits it, while black absorbs most of the light and therefore appears darker.

Can you change an electrical outlet into a switch for a light?

Sure. For a light you need a fixture to hold the light and the light itself. The light needs to be connected to a voltage supply which you can get from the outlet. In the outlet box you will have a black, white and bare ground wire. Essentially you connect the white and bare wires directly to the light and switch the black wire (hot) through a switch.

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

Having two black wires connected to a light switch indicates that it is a switch loop, where one black wire brings power to the switch and the other black wire carries power to the connected light fixture. The two white wires capped off are neutral wires from the power source and the light fixture, which are typically not connected to the switch.

Why aren't black and white colours?

Black is the absence of color, while white is the presence of all colors combined. In terms of light, black is the absence of light, and white is a combination of all wavelengths of light. Therefore, black and white are not considered colors in the traditional sense but rather shades and tones.
