ELCB device and RCCB device are same. Both ELCB and RCCB work from the same system. RCCB is the new version of ELCB.
ELCB is installed in our homes to avoid earthing. If the earthing is not installed in any device, then the human gets a shock of the current. Because the device is not connected to ground. That’s why we should install ELCB in our homes and avoid earthing. It could also be the death of a man to make sense of it.

What Is ELCB Full From
ELCB is an Automating Circuit Breaker Robot and the full name of ELCB is Earth Leakage Circuit Breaker.
What ELCB Switch??
In any circuit current flows in phase, neutral and equipment. Leakage current is generated when any circuit comes in contact with the intended part. Earth leakage flow is undesirable. This is because more voltage is generated across the exposed metal part and if a person comes in contact with it, he feels electric shock. Earth leakage currents can ignite equipment and cause electrical waste.
The main advantage of this device is that very little leakage current trips the main circuit. It also protects the man from electric shock by tripping the circuit when he is electrocuted.
These equipment include a small transformer, operating coil, trim mechanism, test button etc.
The phase and neutral of the circuit to be protected is passed through two windings of a small transformer. The third winding is connected to the trip relay. The contents of the tripping mechanism are usually in the closed position. When a person comes in contact with a live part, the value of the leakage current from it reaches its fixed value, then the tripping mechanism operates and trips the circuit.
The operation of the circuit can be checked as well as reset with the test button.
Such circuit breakers can be used on single phase and three phase supply. Consideration may now be given to making it mandatory to connect this circuit breaker to every electrical outlet. The ELCB is connected to the MCB in the distribution board.
Difference Between ELCB and MCB
| No. | ELCB | MCB |
| 1 | ELCB Full Name Earth Leakage Circuit Breaker. | MCB Full Name Miniature Circuit Breaker. |
| 2 | ELCB operates on earth leakage current. | MCB operates on total current. |
| 3 | There are two types of ELCB 1. Voltage operate Earth Leakage 2. Current Operate Earth Leakage 2 | There are two types of MCB 1. L Series 2. G series |
| 4 | It is used when someone is in mourning (Human) and protects him. | This prevents damage to the equipment during overload as well as short circuit. |
| 5 | It needs a current of 5Ampere to 50Ampere rating. | It needs a current of 100Ampere rating. |
| 6 | It works in two types. 1. To turn the circuit on and off under normal circumstances. 2. Prevents damage to equipment during overload and short circuit. | It trips the circuit when it sees a low leakage current and protects against shock if a person is electrocuted. |
