Answer Posted / ravi
RCCB-Residual current circuit breaker.This is used in
Industrial safety purpose i.e. is to isolate the healthy
circuit whenever earth fault & overload current occurs.we
have in market at different type of ratings 30ma,100ma.as
per requirement will use above ratings.for example human
body having current flowing capacity of 30ma.so in
industrial as per safety constraint they will prefer 30ma
RCCB/ELCB.
