we call them ground fault breakers
10 milliamps thru you instead of the normal current path can kill you
if you have a neon test lamp connect it to one of the hot leads and earth the other.
if it lights the earth leak detector is faulty.
if it opens the breaker its good
most here in the usa have a test button

What is the medical term meaning Procedure used in working of artificial kidney?
The medical term for the procedure used in the working of an artificial kidney is hemodialysis. This treatment involves filtering the blood through a machine to remove waste and excess fluids when the kidneys are unable to perform this function effectively on their own.
What are the four features required to construct a working simple circuit?
To construct a working simple circuit, you will need a power source (such as a battery), a load (such as a light bulb or a motor), conductive pathways (wires) for the electricity to flow, and a switch to control the flow of electricity.
Why is it not advisable to handle electrical circuit with wet hand?
Water is a good conductor of electricity. Should your hands be wet while working with a live electric circuit, the odds are increased that you will accidentally complete a connection and give yourself an electric shock.
If a copper wire in a working electric circuit is replaced by a piece of rubber tubing will there be a current in the circuit?
No, a rubber tubing is an insulator and will not allow the flow of electric current like a conductor such as copper wire would. Therefore, if the copper wire is replaced by rubber tubing, the circuit will be broken and no current will flow.
How do you de energize an electrical circit?
To de-energize an electrical circuit, you should turn off the power source by switching off the circuit breaker or removing the fuse associated with that circuit. Additionally, you can unplug the device or equipment from the power outlet to ensure that the circuit is not energized. Always use proper safety measures and equipment when working with electrical circuits to prevent accidents and injuries.
Describe safe isolation procedure for safe systems of working in electrical circuit?
Shut it off and lock it out. Sign the lockout card and keep your key with you.

Why is it important for the switch of the circuit to be open at the start of an activity?
If you mean by activity, working on an electrical circuit, then it is for safety reasons that a switch is opened. Most companies now use a proper lock out procedure so that everyone is aware that the circuit has been locked out. If more than one person is working on the circuit each person is required to have their own personal lock on the open switch.
If one outlet on a circuit is not working will the entire circuit not work?
No
What happens if a wire breaks?
The circuit stops working because of the short circuit

Will the printed circuit stop all gauges from working?
Depending which circuit burned out, yes.
How can I safely perform a knockout electrical procedure in my home?
To safely perform a knockout electrical procedure in your home, follow these steps: Turn off the power to the circuit you will be working on at the main electrical panel. Use a voltage tester to ensure the circuit is truly off before proceeding. Wear insulated gloves and tools to protect yourself from electric shock. Follow proper wiring diagrams and instructions for the procedure you are performing. Double-check your work before turning the power back on. If you are unsure or uncomfortable with the procedure, consider hiring a licensed electrician for assistance.
What does a short circuit happen?
when the fuse is not working
If a circuit had a gap in it would it work?
Nope... if the circuit has a gap in it - the path of electrons is interrupted, and that would stop the circuit from working.
What is Selection procedure for motor protection circuit breaker?
The selection of overload protection for motors is taken from a table in the electrical code book. It is based on the full load current rating of the motor.
