of 5A and 100A....Genrally if we use on LTside we can use
5A and its class...for 100A it genrally prefer on HT side
like HT panels, Metering cubicles......why we are using CT
because how much Current we are consuming and it placed on
Outgoing cable of Incoming breaker....CT's outgoing we can
use the control wiing like LOAD manager, Relays because
