I think Main Incomer is like our house main switch like 60 Amp
and feeder is like our lighting switch or sub main breaker.
Because all the VCB structure of incomer and feeder is same but different is its current carrying capacity .Most of the incomer is for eg 33 kV , 1250 Amp and the feeder is 33 kV 630 Amp.
