i dont know, i want to know aswell. eeek.
The RCB/RCD is placed between a 3-wire supply and its load, for example between a wall-socket and a kettle.
The supply must be one with a live, a neutral and an earth. In normal operation equal and opposite currents flow in the live and neutral wires, with no current in the earth wire.
But under fault conditions there could be unbalanced currents in the live and neutral, with the balance flowing in the earth wire. That indicates danger and the device detects it and turns the power off.
Most RCDs operate with a fault current of 10-30 milliamps, that is 0.01 to 0.03 amps.

Need of isolator on both side of circuit breaker?
Before anyone is allowed to work on a high-voltage circuit breaker, it must be tripped, electrically isolated, earthed (grounded), barriers/warning notices put in place, and a permit to work document issued by an engineer to the senior member of the maintenance crew. 'Isolation' means a physical (and visible) break in the conductors between the circuit breaker and any potential source of supply -and this is provided by placing isolator switches on each side of the circuit breaker. Without these isolators, the circuit breaker would remain energized, even though the circuit has been broken by the circuit breaker.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
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.
What is difference between the mcb and rcb?
MCB stands for miniature circuit breaker , which provides protection against over current. the setting is not adjustable. RCB stands for residual circuit breaker which provides protection against earth fault as well as over current. It monitors the current difference between phase and neutral and if the difference is more than rated value say 200 milli amps it will trip.
How do you work air circuit breaker?
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.

What is a non auto circuit breaker?
A non-auto circuit breaker is a circuit breaker with the trip element removed. Basically, it is a modified circuit breaker that is now a disconnect switch (glorified disconnect switch).
Why do you use isolator on both side of circuit breaker?
Opening a circuit breaker merely interrupts the current flowing through that circuit. It doesn't remove the voltage from the circuit breaker. Isolators (called 'disconnects' in North America) place a visible gap between the circuit breaker and energised conductors, allowing work to be performed on the circuit breaker safely. The full procedure involves: 1. Tripping the circuit breaker (CB). 2. Opening both isolators. 3. Applying temporary earth (ground) connections on either side of the CB. 4. Placing barriers and warning signs around the CB. 5. Issuing a permit to work card to the maintenance supervisor.
Why is the circuit breaker stuck in the middle position and how can it be fixed?
The circuit breaker may be stuck in the middle position due to a tripped mechanism or a faulty internal component. To fix it, first try resetting the breaker by switching it to the off position and then back on. If that doesn't work, consult a qualified electrician to inspect and repair the circuit breaker.
