What’s the difference ELCB, RCCB?
Answer:
ELCB and RCCB are both electrical safety devices that protect against electrical shocks. ELCB stands for Earth Leakage Circuit Breaker, while RCCB stands for Residual Current Circuit Breaker ¹²³⁴.
The main difference between the two is that ELCBs detect leakage current and disconnect the circuit when a fault is detected, while RCCBs detect residual current imbalance and trip the circuit when a fault is detected ²⁴.
ELCBs are voltage-operated devices that are no longer available and it is advised to replace them if you find one.
RCCBs are the new name that specifies current operated (hence the new name to distinguish from voltage operated) ¹³⁴.
