looking for solution , i come to know type A rccb is suitable for Inverter AC. besides type ac are very much avaliable in India. locally you will found only type AC rccb . few online retailer sells type A and Type B which is suitable for Inverter AC but have not much variety brand .(like -schneider,legrand,ABB) they only have hevells and price is too high for(63 A or 40 A 2 pole).
type AC rccb cause frequent tripping on Inverter AC.what should i do ? should I buy RCCB type A or Type Ac or drop the plan anyway?
I don’t think there is a much need for putting AC on RCCB.
If you really want to, try a bigger range RCCB tolerance. Generally 30mA and 60mA are available. Get a higher range.
i try to use 1 rccb for everything
i dont have seperate DB box for whole system , old fashion house wiring with single common netural wire. if install as a common rccb like
SUPPLY→RCCB(type AC )→2 MCB →5 rooms (light +1 water pump+Fans+ 1 inverter Air condition(1 ton)i+ extra load +/- )
that i think RCCB would a mismatch. i estimate around 40/63 amps would be require for whole stsyem. and 63A type A rccb does not avaliable in local or any market .
40 A avaliable type AC everywhere, i dont know 40Aor 63A TYPE AC rccb would be compatible with inverter AC And household 1 common neutral system
