Where do I find ground wire for my mobile home?

Find the green ground wire that comes out of the main disconnect. Connect the ground wire from the main disconnect to the grounding rod conduit according to the grounding rod's instructions. Install no more than 1/4-inch thick copper wire on a 2-inch diameter metal conductor. Grounding is needed in case electricity from another circuit enters your home through a water pipe, underground cable, or appliance plugged into an extension cord. The gas company will connect you to a free electrical outlet by running a second set of wires (called a ground) along with the first set.

The telephone company may have installed some new outlets in your area that are ready to use. These are called "3-wire outlets" because they can accept any color wiring (black, white, red). If you see blue or green wiring, it must be connected to a fourth terminal (ground) for these outlets to work. You'll need to call your phone company to have them send someone out to connect your new appliances. They'll do this for free if you confirm that it's okay to leave them open later during construction!

Grounding is also necessary if you want to be sure that an electric fence won't shock you when you touch it. Electric fences are common in farms and other rural areas; they protect crops and livestock from predators like deer and coyotes.

Is there a ground wire from the house to the garage?

This is what I did: I ran #4 (AL) triplex wire from the home to the garage (2H, 1N) at the garage disconnect. I have a #6 ground wire that connects to the ground rod. This is a vintage garage from the 1940s or 1950s. There are no additional options for grounding. The metal panel has three slots for wiring connections: one for power, one for optional equipment control, and one for ground.

There should be a ground wire from the meter to the garage. If not, you have an electrical problem you need to address first.

If the meter's ground terminal is connected to the third slot on the metal panel, then there should be a ground wire from this terminal to the garage.

You should see if you can locate the ground wire at the meter. It may be hidden under some plastic tape. If so, cut it off with a knife and strip away any insulation from the copper sheath. Connect it to the third slot on the metal panel at the meter. Make sure you connect the ground wire at the meter to the correct terminal on the panel!

Now check the garage again. Should there be a ground wire from the house to the garage? If so, great! Otherwise, you'll have to find another way to connect them together.

How do you install a ground wire?

  1. Turn off the main breaker.
  2. Remove faceplate from the service panel.
  3. Thread the ground wire through the knockout hole in the appropriate location (usually on the bottom or the side) on the service panel.
  4. Locate grounding bar and attach the ground wire.
  5. Replace the service panel faceplate.

What if I have two ground wires?

The two ground wires, as well as a 6-inch length of green or bare ground wire known as a pigtail, must be wire-nutted together. Three holes in a grounded electrical outlet offer a ground connection for three-prong connected devices. Turn off the circuit breaker that controls the outlet you're working on. Then remove all metal objects from around the hole until you can get to them with a nonmetallic tool such as a screwdriver. Connect the black ground wire to the metal shell of the outlet, using the black wire from your device's power cord.

If there are no metal parts accessible to install a ground fault interruptor (GFI), then you will need to use a nonmetallic tool to connect the ground lead from the GFI to an unoccupied hole. The GFI has screws on its face to mark which hole is for the ground lead. Follow these instructions carefully so that you do not create a hazard.

The National Electrical Code requires that all circuits containing a telephone be equipped with a device called a ground fault circuit interrupter (GFCI). This type of protector tests the voltage between the line and ground wires every time you plug in a phone. If there is a difference in voltage, this means that someone may be trying to reach through another conductor and complete a circuit with your live current. The GFCI will stop this from happening by opening both lines into the outlet to shut off the power before it causes damage.

How do you wire an electrical box?


  1. Check Feeder Wires for Power.
  2. Open Knockouts in Box.
  3. Mount the Circuit Breaker Panel.
  4. Install the Main Service Wires.
  5. Connect the Main Ground Wire.
  6. Connect the Main Service Neutral.
  7. Connect the Main Breaker.
  8. Pull Wires for Branch Circuits.

Can all the ground wires be connected together?

You should connect all of the ground wires, however in actuality, it doesn't really matter as long as none are unplugged. The metal parts of a house are not meant to be connected to each other so this is fine.

The National Electrical Code requires that any ground fault circuit interrupter (GFCI) installed in an outdoor power outlet be connected to the house wiring. This means that if you have a GFCI outlet and it shuts off power to your yard, the ground path to earth must also be broken for these outlets so they can function properly.

If you plan to have people working on your property who may come into contact with electrical power, such as a cable technician, then they should always wear protective equipment. This includes shoes without metal objects inside them, a lab coat, etc. People will be able to work on their own body weight load without worrying about being hurt by electricity if it's insulated from their skin.

Electricity is dangerous because it flows through a conductor- the human body- and can cause injury or death if it gets inside the body. There are several ways this can happen including through the mouth, nose, or eyes. If you're working on someone's home electrical system, take the necessary precautions to prevent accidental contact.
