Re: what is the specification of rcd and based on what if i already have a mcb instal

mcb's protect cable, rcd's are used to prevent fire from electrical faults and reduce the shock level to humans

The RCD rated load current should be, at least, equal to the rating of the MCB or MCCB supplying it. In this case 10A and 30A or greater.

Edit: DO NOT POST THE SAME QUESTION TWICE.
