First let me ask what are you powering with this. This part may not need a ground but the part it is running may need it.
Are you running this to a receptacle or a motor if so then that ground needs to go to that item
I ground even light holders if I can
If what you are powering does not need a ground such as an outlet, motor, or something of that nature then tape it with tape and leave in the box .use electrical tape

The boiler frame should have an EARTH ground. Everything in the system uses the frame for all the needed grounds. A wire from anywhere on the frame to a good connection on a water line is normally what is used when the boiler is installed.

Recheck your connections.The wire colors may not have been wired in the standard way when HVAC system was installed. I remember the instructions on my Honeywell thermostat(replaced mine about 2 months ago) stated that you should look at the wire LOCATIONS on the 'stat you're replacing and tag the wires according to this,not the wire color(too late in your case).You'll have to verify the wires.Disconnect them(don't worry about noting where they were as it's not right anyway).Using an A/C voltmeter,locate the hot feed to the 'stat(ground one lead of the meter at a nearby outlet and look for 24v on any of the wires).Tag it as "feed".Now,touch this to each wire until you find one that turns on the ventilation blower and tag it.Try the other two,one of them should turn on the outside A/C condensor unit(this is the A/C wire).The remaining wire's gotta be the furnace,but verify anyway.This should be enough to get you back on track(don't feel bad,the instructions in my 'stat confused me a little,even though I've replaced mine a couple times before).PS- I think the blower fan wire goes to the terminal with the little factory jumper wire-this is so you can set it up to run the same fan in heat or A/C(factory setup) or remove the jumper to run a seperate fan for each(highly unusual setup but possible)

I dont have the orginal ground wire for my Technics SL-BD20D turntable someone told me i could use rca cables to ground it, i have a pre amp cause my main amp didnt have phono jacks on the back of it.

You don't need the original ground wire for Technics SL-BD20D turntable,
any plain cable can be used for this purpose...
you should connect turntable to your pre amp,should be a "phone" input at the back...
here are some suggestions for grounding....
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    Make sure that the receptacle that it's plugged in to is still working. The circuit breaker for that outlet may have been tripped in your home's circuit breaker panel. Or there may be a loose wire or bad connection inside the outlet box. May not be air purifiers fault at all.

    2006 Dodge Dakota - power outlet doesn't work. The #28 fuse checks fine.

    Take a 12v test light and wrap the probe with electrical tape, leave about
    1/4" exposed. With the key on, ground the test light wire and insert the
    probe into the outlet and touch it to the center power contact. If the light
    stays out and you have a good ground, you don't have +power at the
    outlet. If the fuse is good, you may have a bad wire or socket. But if it
    lights up, we go to the next step. Touch the probe to a known +power
    source and ground the wire to the metal side in the outlet. If you don't
    get light, check the ground for the outlet socket. Repair as needed.
    If it lights up, then you know you have power and ground. Check the
    plug on the device you're trying to use. I hope I was of some help.
    Good luck.

    Kenmore model 110 ele dryer has 3 wires giong into outlet but outlet is going to be connected to a 4 wire supply. red black white green which color is hot what color is ground how do i connect the...

    This sounds like you should call an electrician, or someone that knows wiring. Red and Black are both hot, White is neutral, and Green is ground. Remove the ground strap from the center of the terminal block to the case. Put green wire to the case, white in the middle, and red or black to either side. Your last question I do not understand. But it sounds like you need an electrician to connect a 4 prong receptacle, with the proper 4 conductor wire to your breaker box.

    I just bought a used amana dryer that is 1 year old. it has a 3 wire pigtail and i have a 4 wire plug in and need to change out the pigtail. need some direction on if possible to change it out or will i...

    Two options,

    1) get a three wire outlet ("plug in")
    2) get a 4 conductor cable.

    The 4th wire is green or bare - ground the wire to the cabinet.

    You are 'safer' with the 4 conductor wire. (In the past, White served as the neutral conductor and the case may have been 'bonded' to the white, providing a "ground". Today, I believe the code requires a separate ground. Even though the white and green join in the service panel and go both to ground and "back" to the utility, there is the possibility some installations are wired through a sub panel. Common use of white as neutral and ground is not allowed in a sub-panel in most jurisdictions). Black to black, Red to red, White to white and Green (or bare) to the frame. You can make a hole and connect it or use an existing screw that is nearby to make the connection.

    If you have a volt meter, you can check your existing outlet. You should get 220 V between the two legs, 110 V between "red" and "white", 110 V between "black" and "white", 110 V between "red" and "ground", 110 V between "black" and "ground", and no reading between "white" and "ground".

    The terminals on your existing outlet should be clearly marked and the color code of the wire should be clear although it is POSSIBLE the color of the conductors is all black. The above series of tests will help you determine what is what if necessary.

    If you are still unsure, you should get the advice of a licensed electrician in your area (which I am neither)

    I hope this helps you

    Dryer outlet does not have common wire.

    You can replace the 4 prong with a three prog cord found at Lowes etc.

    First, disconnect the black wire, one of the "hot" connections, from the left side post by removing the terminal screw. This is one-half of the 240-volt connection.
    Next, disconnect the red wire, another of the "hot" connections, from the right side post by removing the terminal screw. This is the other half of the 240-volt connection.
    Then, disconnect the white wire from the center connection. It is used for the neutral connection.
    Now, disconnect the green wire from the machine case by unscrewing the green screw.
    The next step is critical to return your electrical connection to factory condition before installng the 3-prong cord! Locate the white machine wire that is now connected to the neutral (center) screw terminal. Disconnect it from there and install it under the green ground screw.Connect the outer two wires (hot wires) to the outer two screws, obviously, one on each screw.
    Now connect the center wire (neutral) to the center post. You'll notice the white machine wire is now the case ground connection, unlike the 4-prong cord connection in which the green wire from the cord makes the ground connection.

    I have a four wire on a 20 Amp service. I need 110 outlet.

    4 wire recepticals are used for 220 Volt appliances, there should be 2 hot (117V to ground) and one each Grounding and grounded (read neutral) conductors) Breaker or disconnect should be 2 pole for 220 Volt circuit. A 20 Amp 110/117 Volt circuit would have a single pole breaker or disconnect, one "hot" conductor(should be black or colored , not green or white), one neutral conductor (should be white or neutral with white stripe) and an equipment grounding conductor (should be green or bare copper). It sounds to me like your receptical was wired for 220 V using whatever colored wires were handy. Back up to breaker or fuse (disconnect), and shut off circuit. New 117 Volt outlet will be wired with Black to Brass colored screw (short slot on face), One White wire will be used for Neutral conductor (make sure you know which one it is at the breaker panel) and one of the other white wires may (but shouldent be) used for ground (use green marker to identify it at each end),The third white wire should be removed if you can, otherwise cap with wire nut at each end and coil up in back of boxes. At the breaker/ fuse panel, the Black wire is connected to the breaker (It will be your "hot" lead), The white being used for the Neutral is connected to the neutral buss bar with the other Neutrals, and the green goes to the grounding buss bar (should have other green or bare copper wires. Once all is properly connected and secured but without the disposal plugged in, turn on the power and check for leaking smoke (smoke here is a bad thing) The fuse or breaker should protect your wires and help keep that smoke inside the boxes. Check voltages at the new plug, 117 V accross Short and longer slot, 117 from short to ground (round) and 0 or close to it from long (Neutral) to ground. If voltages check, plug in the new appliance and test.
    If in doubt about what you have, dont hesitate to contact an electrician, they get paid for their knowledge and experiance and their ability to keep that nasty smoke inside the boxes.
    Good Luck.,
