Yes, especially for safety reasons.
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
Yes, if there in no ground wire that is acceptable on a home with no ground wires.
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.
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
Most will say that the white striped wire is the ground. The bottom line is that it doesn't really make a difference as long as your amp ground goes to your speaker ground. This is very important!
The ground wire (equipment grounding conductor) runs back to the panel then to a ground rod. If there is a ground fault in the circuit, the current will flow on the equipment grounding conductor back to ground. Electricity follows the path of least resistance. This is why a ground wire is so important and why NOTHING should ever be hooked to a ground wire. It has the least resistance back to source.
It means a wire in the ground.
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.
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.
Yes, it has to be sized to the main circuit feeders to be able to carry the fault current of the main feeders if a fault occurs. Sizing of ground wires for service supplies can be found in the electrical code book. In cable wire sets the ground wire is determined by the manufacturer of the cable.
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.
