MCB means miniature circuit breaker--It is thermal &
magnetic trip device operating upto 100 A. It's range is
fixed not selectable.
MCCB means Moulded Case Circuit Breaker---It is operated
upto 1000 A and High voltage MCCB also operates on 1200 A
also...And it's range is not selectable..

In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
