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 CT and PT?
A CT is used to measure current, and is NOT referenced to ground, and has very low primary impedance. A PT is used to measure voltage, is referenced to ground, and has a much higher impedance (since it is referenced to ground).
What is bgcolor?
bg color is the abbreviation of background color there is a command used in HTML which set the background color which u want
What is a burst gate amplifier?
It is used to separate the color burst signal from the color signal.
What is the color code for steam pipe in industrial applications?
silver is the color that is generally used.
When an isolated ground is required does this mean a separate ground uninterupted from the main service panel or can you take separate grounds to the outlets that require isolated grounds from a sub p?
Answer for USA, Canada and countries running a 60 Hertz supply service.An isolated ground return to the panel means that the wire used for the isolated ground must have insulation on it. This is so that the isolated ground does not touch any adjacent metallic parts of the electrical system until it is placed on the ground block in the distribution panel. On isolated ground receptacles this is accomplished by using a three wire feeder. Black and white wires used as normal receptacle connections. The red wire with a green identifier tape installed to the isolated ground terminal of the receptacle and the bare ground wire to the green frame screw of the isolated ground receptacle.

How much type of grounds are used in the electronic circuits?
The standard electronic grounding system used is the "single point ground", close to that single point the ground splits into two independent ground systems that never interconnect again at any other point: a high noise (digital) ground system and a low noise (analog) ground system. Each of the two ground systems can also split into sub-ground systems (again at a single point with the important thing being that once split they never interconnect again). This produces a grounding system that looks like a tree. Another type of grounding system used is the "floating" or "isolated" ground. This type of grounding system is used for safety purposes and is often UL mandated in the US. In this type of grounding system the real ground used by the electronics is isolated from the user and all external metallic components or surfaces of the device. These external components and surfaces are connected to a second ground called the "floating ground", which is connected to the real ground at a single point via a resistor and capacitor in parallel. The resistor provides DC current limiting to prevent a fatal shock, while the capacitor provides an AC bypass so that at high frequencies the two grounds still act as if directly connected. If multiple power supplies are used, each with its own independent isolated ground, they may either be brought together at the common single point ground of the system, or kept totally independent if the systems they power can be kept completely electrically isolated (e.g. by using optical coupling to bring signals in and out). Grounding in electronics is an art and an unnoticed error can cause endless painful hours of troubleshooting to locate and many more hours to fix.A ANSWER: There many names for ground to distiguish one from the other like shield ground it carries no current because it is a shield an does because it carry the bulk of the power and so on. All grounds eventually tie to a single holy point . So why the difference in names because all perform a duty to carry current and the art is to make sure one do not interfere with the other
What color is the ground conductor?
Depends on what you are wiring. Green is a common color used for ground. Sometimes it is just a bare copper wire.
What is an isolated ground?
When devices are grounded in most electrical system the grounds are combined without order or separation. The same ground that connects the metal box, the yoke of the electrical device and other devices is the same ground that is used at each outlet. This rarely causes any sort of problem except for sensitive electronics such as hospital equipment, high end computers and high end musical equipment. In an isolated grounded receptacle the ground wire is insulated and comes directly from the panel to the ground connection of the receptacle. This type of grounding should produce less electrical noise on the system.
What is a system used to label resistors?
color
What kind of colors are on the Ral color system?
RAL color system consists of many colors used today. From yellow to pearl dark gray, these colors are basic in the creation of this uniques color system.
What plants did the egyptians use to color themselves?
They used henna to color their nails. Most of their make up was made from ground clays and stones.
What is a ground loop isolator?
Ground loop isolators are used to break the DC circuit path for the audio shield ground circuit. It removes ground loops from the system, which are unwanted.
Which number system is used to represent color in digital graphics?
hexadecimal
Is isolated a preposition?
No, "isolated" is not a preposition. It can act as an adjective or a verb, but not as a preposition.
Is gps ground based only?
No..... there are many uses for GPS and they are not limited to ground. They are used in planes, boats and a multitude of other applications. Look at www.findvehicle.net the have a system that can be used on anything.
