The purpose of a residual current device (RCD) is to compare the currents in live and neutral wires. These should be the same. If they are not, then current must be flowing to earth- perhaps through someone touching an exposed wire. The RCD senses the difference and switches off the current before any harm can be done.

What is the name of the device that senses the current flowing tripping the circuit and cutting off the electricity?
The device that senses the current flowing and trips the circuit to cut off electricity is called a Residual Current Device (RCD) or Residual Current Circuit Breaker (RCCB). It detects imbalances between the live and neutral wires, which can indicate a leakage current, and disconnects the circuit to prevent electric shock or fire hazards.
What is a residual current detector?
It is another name for a GFCI (Ground Fault Circuit Interrupter) which is the name used in North America for an RCD (Residual Current Device) as it is known in Europe and elsewhere in the World.For more information take a look at the page reached by the Related Link - and the answers to the Related Questions - which are shown below.
What do tripped circuit breaker and blown fuses indicate?
Blown fuses indicate overload in the electrical circuit. Possible short-circuit or higher input voltage.Tripped circuit breakers I guess means:A residual-current device (RCD), similar to a residual current circuit breaker (RCCB) which is used for breaking the circuit when electric current pass through a man or could cause fire/burning in the/near the electrical sockets.
Why is an Residual current device better than a wire fuse?
- Using an RCD is better than a fuse because it requires no replacement sacrificial metal strip. Also, more reliable and reacts more quickly to cut the circuit (can detect quickly since it is a more sensitive device).
What protective device is used in domestic plug tops?
In domestic plug tops, a fuse is commonly used as a protective device. The fuse is designed to break the circuit if the current exceeds a certain level, preventing overheating and potential electrical fires. Additionally, modern plug tops may also include residual current devices (RCDs) for added safety against electrical shocks.
What is a rccb?
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.

What does it mean RCD?
Residual Current Device. Also known as an Earth Leakage Circuit Breaker or a Safety Switch
What is residual curent?
Residual current as in a residual current device or RCD (sometimes known as a earth leakage detector), refers to the current both entering and leaving a circuit. If more current flows into a circuit then comes out (if there is a ground fault or if someone gets a shock) the RCD will switch off the circuit. Typically the current required to trip a RCD is around 5-20mA, however even 5 mA can be enough to stop your heart, so RCDs are a good safety device but should not be relied on.
How does an RCBO work?
An RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is a device that combines the functions of a residual current device (RCD) and a miniature circuit breaker (MCB) in one unit. It detects imbalances in the electrical currents flowing through a circuit, such as those caused by leakage or faults, and disconnects the circuit to prevent electric shock or fire. The overcurrent protection feature ensures that the circuit is also protected from excessive current flow.
What is purpose of demagnetizing test during current transformer test?
The residual magnetisation present in the current transformer coils may cause the errors during measurement of high currents. So that it is necessary to check that.
Rcds in electrics?
If you mean: "What does Rcd's in electrics stand for?" It means Residual Current Device, which protects household sockets If your question means something else, you should make it clearer. you =P
What is an rcbo?
It stands for " Residual Current Circuit Breaker "
What is the fullform of rccb?
Residual Current Circuit Breaker
How do you check the residual current device is connected to your power tool?
To check if the residual current device (RCD) is connected to your power tool, first ensure the tool is plugged into an outlet protected by the RCD. Next, test the RCD by pressing the "Test" button; it should trip and cut off power if functioning correctly. After testing, reset the RCD and verify that the power tool operates when plugged in. If the tool does not work or the RCD does not trip, consult an electrician for further inspection.
