What color is the ground wire when you have red black and white and I changed a switch that has a night light on it and it says it has to be grounded but these are the only wires i have?

Look in the very back of the switch box. There you should see a screw with a bare copper wire wrapped around it. That is your ground wire. Loosen the screw and add a piece of wire under it and then re tighten it. Extend it out to where you can connect it to the switch. The extended piece of wire should be bare or green so as not to get it confused with the other "hot" and neutral wires. Re install your new switch. Just as a note of interest, when you screw the switch to the box this also grounds the switch frame if the box is grounded. The code states that if there is a ground screw on the switch this must be the method that is used. What this allows is that when the switch is removed from the box the ground will still be intact to the switch for safety reasons.

In standard household wiring, the ground wire is typically either green or bare copper. If you don't see a green or bare copper wire among the red, black, and white wires, it's possible that the ground wire is missing or not connected. It's important to have the wiring properly grounded for safety reasons, so you may need to consult a professional electrician to address this issue.

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.
Should the black wire be bonded to the ground?
It depends on the color coding standards for what country you are in. In the US, the answer is no. The Neutral (white wire) is grounded at the service entrance to the building. The black wire should have roughly the same voltage to the neutral and to the ground. Something to be aware of: If you are using a meter and checking for continuity between the black wire and ground, it may tell you that they have continuity if the breaker is on.
How do you wire a light and switch with the 2 wire old romex?
To wire a light and switch using 2-wire Romex, connect the black wire to the brass screw on the switch, the white wire to the light fixture, and the white wire to the silver screw on the switch. Make sure to cap the unused wire at both ends for safety. Be sure to turn off the power before starting and consult a professional if you are unsure.
How do you wire two outside light sensing motion porch lights that are controlled from one switch with each light having a white black ground and optional red wire?
Connect the black wire from the switch to the black wires of both lights. Connect the white wires together. Connect the red wire, if used for the motion sensor, to the black wires on the lights. Connect all ground wires together and to the ground terminal on the switch. Make sure to turn off power before connecting any wires for safety.
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).
You have got no reverse lights ive changed the bulb what next?
look at the ground wire it should be black Also check the fuse Have your neutral safety switch checked. If you don't have any bad fuses and you've changed the bulbs, most likely it's your neutral safety switch. It's located on your transmission.
How do you wire a garbage disposal between the disposal and the GFI?
White and the ground go to the disposal, black goes through a switch and then to the disposal. All three go through the switch box, the white and ground just pass through on the way to the disposal. Break the black with the switch.
Does positive go to ground in a car battery?
NO! positive is red and black is negative negative is grounded to the frame of the car, and positive goes to the electrical components.
Is the black wire connected to the line or the grounded line when connecting a power cord to a motor?
Black is the hot side of the line, white the neutral side, green (or rarely bare) wire is the ground.
How do you install a 20 amp switch for well pump?
Black/White/Ground power in and the same out. Tie the incoming and outgoing white wires together under a yellow wire nut and push them back in the box. Tie the ground wires together under a green wire nut and connect the pigtail from those ground wires to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Doesn't matter which black wire you connect to which screw.

What if I find a black wire grounded in the light terminal?
Black wire? You mean black insulation? If so, a black insulated wire would generally be a non-grounded conductor (preferably the hot line) and should not be connected to ground anywhere. However, someone may have improperly used a black wire for grounding, rather than green wire (or green/yel wire), or forgotten to wrap it with green tape.
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.
How do you know if a car has a negative or positive grounded battery?
Find the cable that is connected directly to the frame or sub-frame of the car. If it is red, then Positive is ground; If it is black, then Negative is ground. More than likely (but not in all cases) the electrical system is Negative ground.
What is common wire in a three way when all the wires are black?
If this is a new installation then you have a choice of picking any one you wand to make the common wire. Usually a three wire cable used for three way switching has a white, red and black wire in them. If this is an existing installation and you have misplaced which wire is the common you will have to go back to the switch to find the conductor used. Disconnect it from the switch and temporarily place it on the ground wire. Next go to the next junction box and start ringing the wires to ground. When you find which wire is grounded, this is the common conductor.
How do you fix Ford Crown Victoria parking brake light to come on when parking brake is engaged - mine is missing the switch and the wiring?
There is a small (approx. 18 gauge) brown wire and a black wire that run from the drivers side floor board - the two wires are together and end at a tiny connector. The brown is "hot" with key on, the black is grounded. If you are missing the switch (like my car was), you can improvise with a normal pin switch and a metal bracket (I had to dremel tool it to fit). Hook up the brown wire to the bottom of the pin switch and the black wire to the frame of the pin switch (so the wires will be connected when the pin switch is engaged). Install the pin switch so that the switch is disengaged (ie not connected) when the parking brake is off. If you have the switch in the right spot, only a slight pressing of the parking brake will engage the switch, which connects the wires and turns on the "brake" light on the dash! In my car, the pin switch sits about perpendicular to the ground and the "pin" sits in a crevice at the top of the parking brake. This crevice moves upward when you depress the parking brake, which then allows the pin switch to expand. Releasing the parking brake compresses the pin switch. Electrically the brown wire needs to be grounded for the light to come on.
