A Ground or Earth wire is wire used to connect the frames and outer casings of appliances and power supply panels to the Earth.
For more information see the answer to the Related Question shown below.
It means a wire in the ground.
An open ground is a severe safety issue. The ground needs to be connected to protect the user in case of appliance fault. Run new wire with a ground or call an electrician. Have it fixed, negligence is fatal.
That Thermostat is LOW voltage. IT does not have a ground wire. There is no need for a ground. it only opperates on 24 volts. there may be a green wire but it does not mean it is a ground
If there is no ground wire connect the ground wire to the neutral wire.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
If the voltage between real ground and the ground wire is not 0.0000 Volt, then the wire is not grounded properly.
The recommended ground wire size according to the NEC Ground Wire Size Chart is based on the amperage of the circuit.
Some older wire does not have a ground. All you can do in that case is use a jumper wire to connect the ground to the neutral.
the hot wire goes to the starter and the ground wire bolts to the engine block.
