Why is a fuse wire necessary in a circuit?
a fuse wire melts when current passing through it exceeds a certain value as in overloading and short circuiting .this breaks the circuit prventing further current flow and damage ..
What does it mean RCD?
Residual Current Device. Also known as an Earth Leakage Circuit Breaker or a Safety Switch
Which electrical safety device melts easily during a short circuit or overload?
You're talking about a "fuse". The fuse doesn't know anything about "short circuit" or "overload". It only knows that the current through it has exceeded its rated value, but nothing about how or why that occurred.
What is the name of a safety device that will shut off flow of electricity?
Devices used to open an electrical circuit are called OCPD's. (overcurrent protection devices) The most common are circuit breakers and fuses. In commercial motor starters they often employ another OCPD called a "heater" (UK thermal fuse) which is a metal strip which melts like the element in a small fuse when too much current (amps) go through it. They devices are in the circuit primarily to protect the wiring and devices they power. Circuit breakers such as in your home panel do protect you from a "shorted" circuit. Another safety and most common in residences are GFCI's or ground fault circuit interrupters (UK ELCB, Earth Leakage Circuit Breaker or RCD, Residual Current Detector) which come as both a receptacle (female plug) or as a circuit breaker.
What are the safety features available in a breaker?
To detect and open the circuit if a thermal overload is present and to detect and open the circuit if a short circuit caused by a magnetic increase of flux in the circuit.
Is a reusable safety switch that breaks the circuit when the current gets too high?
In the electrical trade, this device is known as a circuit breaker.
What are fuses and circuit breakers What are they for?
A fuse is a device that contain a thin strip of metal that will melt if there is too much current through it.A circuit breaker is a reusable safety switch that breaks the circuit when the current gets too high.They are used to prevent circuits from overheating.
What happens when a fuse blows?
When a fuse blows, it essentialy breaks the circuit. So the current can no longer flow, this is used as a safety measure.

Is a circuit breaker a resistor?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
How does a fuse help safety?
A fuse is a safety device that helps prevent excess current flowing in an electric circuit.
Is a circuit breaker a safety device that monitors the current flowing thouugh a cicuit?
Yes. It is designed to "trip" (Open the circuit) when an over-current situation is detected.
What are the uses of the relay?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
What is advantage of digital relays?
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
What does it mean RCD?
Residual Current Device. Also known as an Earth Leakage Circuit Breaker or a Safety Switch
How are circuit breakers connected with the other elements in a circuit?
Both of these devices are safety devices used to open a faulted circuit and stop the current flow.
Can a circuit breaker be reset and used again?
A circuit break will reset until it mechanically breaks down. What you should be looking at is why is the breaker tripping all the time. A breaker is a safety device that stop current from overloading the wire that it is protecting. When the breaker trips check and find out what other devices have stopped working. Total up the wattages. If the total is above 1500 watts then something is going to have to be disconnected on that circuit.
