Earth ground, in many cases - is used as a reference. The potential of a conductor who is directly connected to Earth Ground has a very low, consistant potential. It is used to help "define the electrical potential of conductors RELATIVE to the Earth's potential."
A protective earth or P.E., is used to provide a path for current flow to prevent an end user from becoming exposed to a live component or conductor, mostly due to failing insulators (IE a short circuit melting a piece of insulation, exposing a live conductive wire that is in contact with the enclosure of a product - in which the user may be in contact with). The entire purpose of the PE is to provide a barrier between the end user and the live conductors to prevent shock hazard.
The purpose of earth ground, is to provide a constant reference potential for other conductors.
Protective earth is a conductor intended to dissipate current in a fault condition to prevent electric shock, while ground can refer to any reference point for electrical potential. In some contexts, ground and protective earth may be interconnected, but they have different functions and purposes in electrical systems.

What forms a protective boundary between earth and space and provides conditions suitable for life?
The Earth's atmosphere forms a protective boundary between Earth and space. It consists of gases that shield the planet from harmful solar radiation, regulate temperature, and provide oxygen for life to thrive on Earth.
Difference between earth soil land and ground?
"Earth" refers to the planet we live on, "soil" is the top layer of the Earth's surface that supports plant growth, "land" is a specific area of the Earth's surface that may include soil, and "ground" is a broader term that can refer to the surface of the Earth as well as the soil, rocks, and other materials beneath it.
Is earth marked on a 12 volt switch also used as ground?
No, the Earth mark on a 12-volt switch typically indicates the connection point for protective earth or ground wire only. It is not used for electrical circuit operation but rather for safe grounding of the switch enclosure to prevent electrical shock hazards.
What is the Difference between the surface and subsurface?
The surface refers to the topmost layer of the Earth's crust, while the subsurface refers to the layers underneath the surface down to the Earth's mantle. The surface is where daily activities occur, while the subsurface is significant for resource exploration, such as mining and drilling.
What is the movement of water between the ground and the atmosphere called?
The movement of water between the ground and the atmosphere is called the water cycle. This includes processes such as evaporation, condensation, and precipitation that cycle water between Earth's surface and the atmosphere.
What is the difference between selv and pelv transformer?
the difference between pelv and selv is that pelv can have a protective conductor(earth)and selv cant.
Can you use the earth wire between room stat and honeywell board as a neutral?
ABSOLUTELY NOT!The protective earth ground wire is only there to provide a low resistance path to ground in the event of a short circuit so as to trip the protective device. Operational current is never, under any circumstances allowed to be passed on earth ground. Use neutral for neutral and ground for ground.CONSULT A QUALIFIED AND LICENSED ELECTRICIAN !!!!
What is the difference between a fault and a fold?
a fault is a large crack in the earth. a fold is when the ground gets bent.
In the electrical system of the US what is the difference between the neutral and the PE Ground?
US NEC: The neutral conductor is an insulated grounded conductor used as the current return in a circuit. The color designation for neutral is white. The protective ground (PE, protective - earth) is a non-insultated grounding conductor used to shunt fault current to ground, tripping the protective device. The color designation for PE ground is green. Neutral and PE ground are tied together at the distribution panel. PE ground is also connected to a solid earth ground, such as grounding rods driven into the earth. Downstream of the distribution panel, PE ground is never used to carry operational current. Any current flow on PE Ground, other than parasitic current, is considered a ground fault, which must be corrected. In fact, GFCI (Ground Fault Current Interrupting) breakers will trip when neutral current does not match hot current, an indication of PE ground current flow.
What is the difference between a peanut and a monkey nut?
There is no difference. Monkey nut is another name for peanuts, as are goober peas, ground nuts (or earth nuts) and pig nuts.
What is the difference between protective and functional earth?
protective earth (PE) is a conductor, other than a main earthing conductor, connecting any portion of the earthing system to the portion of the electrical installation. functional earth (FE) is an earthing arrangement provided to ensure correct operation of electrical equipment or to permit reliable and proper functioning of an installation
When you test the outlet you get no current between power and neutral but you get it between power and ground?
There is an open circuit on neutral. You should have power between hot and neutral, as well as between hot and ground. Note well, however, that you should not pull any power between hot and ground, because ground is not intended to be a current carrying conductor - it is only there as a protective earth ground in the case of fault. You can not easily tell, at the outlet, if neutral and ground is reversed - you need to pull a load and then double check with a clamp on ammeter at the distribution panel.
Should 230Volts exits between live wire and protective earth?
yes
What forms a protective boundary between earth and space and provides conditions suitable for life?
The Earth's atmosphere forms a protective boundary between Earth and space. It consists of gases that shield the planet from harmful solar radiation, regulate temperature, and provide oxygen for life to thrive on Earth.
Why is it dangerous when ozone is near Earth's surface?
Ozone is a protective substance at the atmosphere level. It can be dangerous as a pollutant at the level of ground.
What is a difference between a spring and a well?
A spring is where water rises above the ground level from a given point in the earth and a with a well, you have to dig down into the earth to reach water and then pump it up to the surface.
What if you test the ground terminal with live conductor?
If you touch the live conductor to ground terminal, it results into a severe earth fault between ground and live, drawing huge fault curent. The protective devices if connected in the system, will trip offf. It is extremely dangerous to do so intentionally. Avoid this at all costs.
