Why we can use elcb and how much mA we use for current or shock

Question

Accepted Answer

ELCB is used for electrical safety by detecting and interrupting abnormal current flow. The mA used for shock protection varies.

ELCB stands for Earth Leakage Circuit Breaker.
It is used to protect against electric shock and fire hazards caused by faulty electrical equipment or wiring.
ELCB detects the leakage current flowing to the earth and interrupts the circuit to prevent electric shock.
The amount of mA used for shock protection depends on the specific application and safety regulations.
In general, the mA range for ELCB is between 10mA to 100mA.
For example, in residential settings, ELCBs with a sensitivity of 30mA are commonly used.
In industrial settings, higher sensitivity ELCBs may be required, such as 100mA.
The appropriate mA rating should be determined based on the specific electrical system and potential risks.
