What wire do you connect the ground wire from your car to if the ground wire from your stereo needs to be attached to metal?
Adion
The negative battery cable bolts to your engine block and body/chassis of the vehicle. Which means that any metal part of the car is essentially the negative terminal of the battery so whenever you need to ground or earth something on a vehicle you simply find a bolt, nut or screw attached to a metal part of the vehicle and attach the wire to it.
if the ground is from your old stereo either follow it and ground you new stereo there or wire them together uses heat connectors. better yet buy a wiring harness and don't worry about the whole mess.

What to do with ground wire in wall when wiring metal light fixture without ground wire into plastic outlet box with ground wire Basically wall has 3 wires fixture has 2 and no place to ground to?
Don't worry about it some fixtures have no ground terminals. just shove the groung wire to the back of the box. Correction, if the fixture is metal and it shorts out, the metal surrounding the fixture could become electrified. That's why fixtures today are normally grounded to their mounting plates and then the lead is attached to the incoming romex. In the past, attaching these plates to metal boxes (either grounded by an incoming wire or grounded to the BX cable) eliminated the need for a ground wire. If the hot wire hit or shorted to the fixture, it would blow a fuse or circuit breaker. Many electrocutions and fires later, the folks at Underwriters realized that even that method of grounding wasn't sufficent (the old aluminum boxes and bx cables were crappy conductors. Solution; (and I practice what I preach because I remodel many old homes) get a little creative and spend the extra time to wrap a little ground wire to a mounting screw, or piece of metal, on the mounting plate of the fixture and then attach it to your incoming romex ground. On an old fixture, it could mean the difference between a fire and a tripped circuit breaker. If you have any metal boxes, old or new, ground to those too. <><><> Connect a pigtail to the metal canopy, and use a wire nut to connect the safety ground to it.
What do I attach the green wire from the light fixture to?
The green wire on the light fixture is a ground wire. If there is no ground wire in the conduit, the green wire should be attached to the metal box with a screw.
Can you connect a ground to a neutral bar?
In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Can you connect a 3 wire fan into a 2 wire supply?
yes....the third wired can be connected to a metal housing of the 2 wire supply as a ground
How do you wire an older 2 wire 30 amp compressor to a 3 wire 30 amp dryer plug?
I am guessing that the dryer is 220-240 VAC as is the compressor. I also assume that the third wire on the dryer is a ground. You need to make sure that the metal chassis on the compressor is not connected to the two wires. You then need to create a covered junction box where you have the two existing wires and a ground wire that you connect to the compressor metal chassis with a screw type connector. Ground wire should be 10 AWG. Now you have three wires. Connect the two hot wires of supply to two original wires on compressor and ground wire to the chassis ground.
Do you connect the ground cable from your car to the ground cable from your stereo or connect the ground caple from the stereo to metal in your car and leave the other wire loose?
If your connecting a stereo, it's always best to ground directly to the negative side of the battery: however you can connect to a ground under the dash also. Some autos have a ground block at the fuse panel that can also be used but you will need a spade connector. your cars body is the ground.connect the stereo ground to a metal part of the car,leave the battery connected to a ground,engine should also be connected to a ground
Where do you hook the ground wire on a porcelain light fixture on a metal box?
Connect the ground wire to the metal box.
Do you have to Connect both fixture and house ground wires?
If you're asking whether you have to connect the fixture ground to the house ground, you do. The idea is to connect any exposed portion of a metal fixture to ground, keeping anything you would be able to touch from having a hazardous potential on it. The way to do this is to connect the fixture ground (which is connected to the metal chassis) to the building ground (which comes from your electrical panel).
Where do you connect the ground for an amp on a 99 accent?
Any metal that connects to the frame
Why you should connect your TV antenna to a metal rod that is driven into ground?
In case of a lightening strike.
Why should you connect your washing machine wire to a metal rod that is driven into the ground?
To ground it. Washing machine build up a lot of static electricity.
How do you ground a car wire?
Connect it to the frame/chassis -- the major metal parts of the car, such as the walls of the engine compartment.
What is meant by earthing?
The same as 'grounding' , putting a wire or metal stake into the ground so something attached to it has the same electrical potential
What is a suitable ground on a quad?
The frame is the best ground source on nearly all vehicles (assuming it uses a negative ground system, which is the most common type-negative post of battery is attached to the frame). If the frame can't be used, a metal part attached to the frame *may* be substituted, but always make sure to clean the attachment point to BARE metal, as paint or powder coating can act as an insulator, preventing a good ground connection.
Can you connect the ground wire from a light fixture to anthing in the metal box that does not have a ground coming from it?
I always connect the ground wire to the box. However, if there is no real ground wire running back to the panel it really does you no good. The NEC requires that you rewire the circuit with the proper conductors. Remember that the ground is for your protection. Without a proper ground, you run the risk of injury or death if the fixture wiring fails.

How do you ground a computer?
Grounding an electrical or electronics device commonly refers connecting it's power inlet ground pin to the ground connection of the power outlet. The power outlet ground connects to the ground connection provided by the electricity utility company or the building's common ground connection. The grounding essentially provides a zero volt reference. Many systems which have a metal chassis provide specific grounding points with screws/nuts to connect grounding wire. To ground chassis of a computer one need to connect ground wire to the metal case.
