Please if someone tell me about the criteria while designing a feeder and branch circuit MCB and MCCB. I mean if am to design a circuit which consist of 4 sub circuit and each sub circuit feeding identical loads. The loads are 4 x 1.5 Ton A/c, a water kettel, Microwave, Refridgerator, exhaust fan and 4*36W lights*4. So my total load would be (4*2000 + 1000 + 750 + 500 + 100 + 4*144= 11KW or 20Amps 3 phase ). The supply here is 415/240V , 50Hz. Please help !
