No. Absolutely not. The ground conductor is not rated to carry constant current flow. It is only rate to carry fault current flow.
If you live in Europe, then the brown wire is the line ('hot') conductor; a blue wire is the neutral conductor, and a yellow/green striped wire is the protective (earth) conductor.
The process is called grounding. Many devices need to be grounded, hence the U shaped pin on a devices that make contact with the ground in normal house wiring.
Typical house wiring in the United States is: Green or bare copper = ground White = neutral (Center tap of the feed transformer) Black or red = hot.
In house wiring it's typically a bare copper wire. It may occasionally be green.
copper is a good conductor
You'll have to explain your problem better.If HOT black and Neutral White in your house wiring are both hot then Neutral is NOT bounded to ground in main panel and neutral could be floating. There should be no voltage between Neutral and Ground (Bare wire in panel). By code if there are multiple panels Ground is only bonded to Neutral in th emain entry panel. I have seen cases where this bonding was not done. At your main panel check voltage between neutral and ground. It should be zero.
In common house wiring, black is the power wire, white is the neutral, and green is the ground wire.
In house wiring you have hot (Black), neutral (White) and ground (Bare wire).
Answer for USA, Canada and countries running a 60 Hertz supply service.The grounding electrode conductor is brought into the main disconnect section of the distribution panel and a connection is made to the neutral block. The terminations in the panel at this point are two incoming "hots" to the main breaker and a neutral wire to the neutral terminal block. In the neutral termination block there is a ground screw that screws through to the distribution panels metal enclosure, there by making the metal enclosure the same potential as the ground plate or rods and the neutral wire that comes in from the street. The grounded circuit conductors of the wiring system are terminated on a separate ground buss that is located in the circuit breaker section of the panel. This buss is bolted directly to the rear of the distribution panel's metal enclosure in the circuit breaker section of the distribution panel. This ground buss is at the same potential as the ground electrode conductor above because of the grounding screw that connects the neutral block to the metal enclosure. Code requires when wiring sub panels within the same building that the neutral block screw be taken out of the circuit and a separate ground wire be run directly from the main distribution panel. This is to prevent any short circuit currents from the sub panel traveling back on the sub panel feeder's neutral wire.In house wiring you have earth ground connect to the ground bus in the main electric panel. Your neutral bus is "bonded" to the Ground bus only at the main panel. When you run branch panels you do not connect neutral to ground in these branch panels, only the main panel. There is typically a screw in an electric panel where the bonding occurs.
Do a physical inspection of all wiring connections.
most vehicles use earth/ground return through the vehicle body, high risk loads, petrol/gasoline the truck is wired like a house with a live feed and a wired neutral return path not requiring the body to be a conductor. The way you would have to wire a car with a plastic/fibreglass body
Silver is the best electrical conductor. Copper is second. Gold is third. Aluminum is a good conductor but not for house wiring. It is used for high tension wires.
