When using an extension cord you need to use a ground fault interrupter?

A Ground Fault Circuit Interrupter (GFCI) senses a leakage path to ground that could be a shock hazard and is mandated in areas where water is involved like bathrooms and kitchens. If you are using an extension cord in a wet area it would be a good idea to connect it to a GFCI protected circuit.

What neutral ground resistor?
Neutral Ground Resistor is using for minimizing the fault current of system. It is a resistor which connected between ground and neutral and increase the resisting path for fault current.
How does a ground fault circuit interrupter work?
== == If the current in an ac power circuit is not balanced between hot and neutral, possibly meaning some of the current is going through a human being to ground, a GFCI breaker or receptacle will break the circuit to keep the person from being electrocuted.
Is a ground wire considered a conductor when figuring on amount of conductors in a pipe?
In the CEC, if pipe fill is used using table 6, ground wires are not included in the count. If pipe fill is used using cross sectional area of conductors and pipe then the ground wire must be included along with the current carrying conductors. A continuous metallic conduit system is considered a ground return path for fault currents.
Is it harmful to plug an extension cord into another on identical to it?
Not in general. You can buy extension cords in a variety of lengths. However, the longer the cord the more the resistance and the bigger the voltage drop across the length of the cord. If you were using the cord outdoors and the junction was on the ground it is possible for moisture to cause a short at the junction.
Do you need arc fault breakers if you put in a new panel in a old house?
If your jurisdiction is using a version of the NEC that requires arc fault breakers, then yes. Call your local building and planning department to see what revision of the code they are using. The exception to this is that you cannot use arc fault breakers if the circuits in question are wired as multiwire circuits (two or more individual circuits sharing a common neutral) because the arc fault breaker won't work in that arrangement. You're not required to replace the entire electrical system just to change a load center, so in this circumstance you wouldn't need them. If you're using the 2005 NEC, you only need arc fault breakers in the bedrooms. If you're using the 2008 NEC, you'll need them just about everywhere that isn't covered by ground fault breakers.
Can you glow led by using neutral and earth?
If you connected neutral and earth (ground) to each lead in an LED and it glowed then this would be evidence of a ground fault.
What neutral ground resistor?
Neutral Ground Resistor is using for minimizing the fault current of system. It is a resistor which connected between ground and neutral and increase the resisting path for fault current.
Why neatural ground resistor using in 33kv transformer?
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.
Why does the reset button on a wall outlet pop out when something is plugged into it?
Assume this is a ground fault circuit interrupter (GFCI) outlet. The GFCI looks for current that is flowing to ground, in a manner that could result in electrical shock to a user. The appliance that is being plugged in could be defective, the wiring connected to the load side of the GFCI may be incorrect, or the GFCI outlet could be defective. Try using another appliance. If the GFCI holds, the first appliance is most likely the cause.
How can you have a ground fault protection in a 3 phase 3W system?
3 phase ground fault detection on a 3 phase system requires that the vector summation of all three phase currents be measured. The vector sum of these currents should equal zero, or nearly zero for a balanced system. If a ground fault exists, then the vector sum will not equal zero. This condition must be validated using i2t techniques in order to eliminate false trips.
How does a ground fault circuit interrupter work?

What has the author Ghulam Abbas written?
Ghulam Abbas has written: 'The development, implementation and tests of a 3-phase line to ground fault distance algorithm for a power system using a microprocessor' -- subject(s): Microprocessors, Electric fault location
What is a fault in track and field?
Using the term fault in basketball is the same as using the term foul. It means that you touched someone while they had the ball in their hands.
What extension will appear if you don't save your html webpage with the proper extension?
There is no single answer to that. It will depend on what you were creating the web page with. For example, if you were using Notepad, it would have a .txt extension or if you were using Microsoft Word it could have a .doc or .docx extension. So it is down to the software you are using and its version that would determine what extension you could have. You can just open and save the file again to fix the problem.

A sentence using the word fault?
Sometimes accidents just happen and no one is at fault. It is never the child's fault when parents divorce.
