Hi sorry i am noob for electricity,
just want to ask, if let say a 100A with 3 phase DB, inside the MCB will need to use 100A each or just add on 20A+20A+20A+20A+20A =100A?
Just add 6A, 15A & 20A mcbs... For protecting the lighting, aircon and sockets ..just want to ask, if let say a 100A with 3 phase DB, inside the MCB will need to use 100A each or just add on 20A+20A+20A+20A+20A =100A?
An ordinary 3 bedroom house would usually use a 40Amp DB and the 100Amp DB is usually an industrial or commercial lot..
