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.
If your house wiring is encased in armoured (metal) sheathing back to the panel, then you can secure the green ground to the ground screw in the box. Make sure the armoured cable connector is tight on the box. This should ground the light back to the panel. If you are on "knob & tube" I would suggest thinking about re-wiring the house.
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).
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.
You would wire the switch to the first light. Code says to break the black or power side of the circuit. Connect the white to the light. Take the black down to the switch on the black wire and back to the light on the white. This is a line of wire from the light to the switch. From the first light, take the white and the return white from the switch to the second with another run of wire. This will be regular black white with ground. White to white and at the first light the return line from the switch is white but hook to the black to the second light. Second light to third just continues the two wires. Black to black, white to white. I think this is clear enough to follow. If not, ask again.
To answer this question fully the type of appliance has to be stated and its voltage.
Yes. Connect Black to Black, White to White and bare ground wires together.
To properly wire a single light switch, you need to turn off the power, remove the old switch, connect the wires to the new switch (usually black to black, white to white, and ground to ground), and then secure the switch in place before turning the power back on.
To wire up a light switch, you need to turn off the power, remove the old switch, connect the wires to the new switch (usually black to black, white to white, and ground to ground), and then secure the switch in place. Finally, turn the power back on to test the switch.
To wire a light switch in a home electrical system, you need to turn off the power, remove the old switch, connect the wires to the new switch (usually black to black, white to white, and ground to ground), and then secure the switch in place before turning the power back on.
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
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.
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.
To hook up a light switch, first turn off the power to the circuit. Then, connect the black wire from the switch to the black wire from the power source, and the white wire to the white wire. Finally, connect the ground wire to the green screw on the switch. Secure the switch in place and turn the power back on to test the connection.
To wire a motion sensor light, first turn off the power to the circuit. Connect the black wire from the light to the black wire in the electrical box, and the white wire from the light to the white wire in the box. Connect the ground wire from the light to the ground wire in the box. Finally, connect the red wire from the motion sensor to the black wire in the box. Secure all connections with wire nuts and mount the motion sensor light according to the manufacturer's instructions.
To wire a light switch to a light, first turn off the power to the circuit. Connect the black wire from the switch to the black wire from the light. Connect the white wire from the switch to the white wire from the light. Finally, connect the ground wire from the switch to the ground wire from the light. Secure all connections with wire nuts and cover with electrical tape. Turn the power back on and test the switch to ensure it is working properly.
If your house wiring is encased in armoured (metal) sheathing back to the panel, then you can secure the green ground to the ground screw in the box. Make sure the armoured cable connector is tight on the box. This should ground the light back to the panel. If you are on "knob & tube" I would suggest thinking about re-wiring the house.
