Ground wire to neutral wire.
the green wire its ground so you have black withe an ground
Connect the ground wire to the exhaust fan housing.
No
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
Thin wire.
ground wire passenger side thin copper wie it is broke
It means a wire in the ground.
To measure the thickness of a thin piece of wire we have got the instrument called the wire gauge. The thickness of a thin piece of wire is measured in mm.
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.
It was quite thin.
it has to do with ohms and the gauge of the wire. if you have a low ohms then you can't use a small thin wire. because the more ohms the more resistance. if you have a low omhs on a thin wire it can cause the wire to heat up. posibly catch fire.
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.
