No
No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.
If there is no ground wire connect the ground wire to the neutral wire.
If a "hot" wire contacts the "neutral" or ground wire, electrical current flows to the ground.
In electrical wiring, the live or "hot" wire is typically brown or red, the neutral wire is typically blue or black, and the ground wire is yellow or green. So, in this case, the brown wire is likely the hot wire, the blue wire is the neutral wire, and the yellow green wire is the ground wire.
'Can' yes. 'Should' no. <<>> Never use a green wire for a neutral. It is colour coded for a reason and that is to protect the people that work on electrical equipment. If you turn a ground wire into a neutral it then becomes a current carrying conductor. There are times in the electrical trade when grounds have to be disconnected and if it is used as a neutral and the tradesman is holding one end and touching a grounded object a shock will occur. Again never use a green ground wire as a neutral.
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 there in no ground wire that is acceptable on a home with no ground wires.
Yes, in a 4-wire electrical service, the neutral wire is included along with the hot wires and ground wire. The neutral wire is used to complete the circuit and provides a return path for the current to flow back to the source.
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
No it is not
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Old three-wire outlets for dryers and ranges were wired with two hot wires and one neutral wire. The ground wire was often omitted, which could lead to safety hazards. When the four-wire system was introduced, it included an additional ground wire for improved safety.
