How does cable sizing calculation gets affected by earth leakage protection?
Ground / earth protection will not impact cable sizing.
How much is the earth leakage current for laptop?
Earth leakage current or ground leakage current is current going where it is not supposed to be going (whether it is on a laptop or not). Power line current should only flow between hot and neutral. The earth or ground line is only there for safety purposes to keep the metal chassis at 0V at all times.
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 the normal insulation leakage current in three phase motor?
zero insulation leakage is known as a ground fault AC, DC, single phase, 3 phase .... same answer on a damp day or with water present it may be a bit higher than zero there is no perfect insulation if you have more than a milliamp you have problems
What is the operation of earth leakage relay?
An earth leakage relay is an electronic or electromechanical device that detects the current flowing to earth (Americans call this ground). If this earth leakage current is above a preset level (and carries on for a preset time) the relay is "tripped" - this may switch on an alarm signal - or more usually it simply disconnects the supply. Currents may flow to earth due to a fault condition or because of lots of individual items connected to the supply have a small "leakage" to earth.
How do you ground a mobile CB antenna when using it as a base antenna?
How do you use a mobile CB antenna for base station antenna?
Can a ground leakage damage electrical appliances?
A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.
Does a ground fault interrupter need to be grounded?
Yes. It is measuring leakage current to ground.
How do you ground a CB radio antenna?
Grounding is accomplished by connecting a heavy cable from the ground side of the antenna to a ground rod. A ground rod is typically a 4 - 8 foot copper plated steel rod driven into the ground as close as possible to the antenna, making the wire connection as short as possible. All equipment should also be grounded to a rod, not just the antenna.
Your stereo is on without a ground what is wrong?
The radio is grounding through the antenna connection. Unplug the antenna and see that it will stop. However you still need to hook up the ground 1st and the antenna last.
Does an ungrounded antenna near the ground act like a single antenna with twice the height?
A better simple approximation would be two antennas separated by twice the distance of the single antenna to the ground.
What 's the type of unwanted current flowing in a neutral conductor?
A leakage current to ground indicates that the ground is not truly an earth ground. A Ground Fault Circuit Interrupter (GFCI) is designed to detect such leakage current and cut off the device from its supply voltage.
1991 capri does the radio need to be grounded separetly oR IS IT ALREADY GROUNDED through THE HARNESS OR ANTENNA?
It is not going to hurt to ground it with a secondary ground if you suspect it is not grounded. It is not grounded thru the antenna. Just run a ground wire from the radio chassis to any ground location.It is not going to hurt to ground it with a secondary ground if you suspect it is not grounded.

Can you ground a antenna with a wire?
no it will mess up the reception
Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current
Will a damaged antenna cable to an aftermarket stereo prevent the stereo from turning on?
no. first check fuses. check ground. check for voltage to memory, and switched power to radio. the only time the antenna would affect the radio in that manner is if the ground was connected to the antenna.
What is the difference between monopole antenna and dipole antenna?
Monopole is an antenna with just the radiating element where the ground of the transmitter is connected to an electrical ground which serves as an Image ground to the radiating element. Thus the name "mono" pole. Dipole is where the ground and the radiating elements are connected to two different elements where one is the radiating element and the other is the ground to the later. Thus the name "Di" Pole Cheers by zafran khan
