Hi ceo64, mind share where to get the 5sj .. seems Google malaysia search didn't give much result

Thanks ceo684
One question , for old house with old wiring , will it have frequent trip if I use 30mA RCD ? I know will have voltage drop for old wiring but for current , total In=total Out + some minor leakge current right , it should not matter if use 30mA for old house right.

Just check, my old house has really old stuff, don even know what the black color stuff is.
The DB box just have mcb, does not have any rcd, any idea which type (40A,63A) i should buy ?
my intention is to improve the house electrical safety , probably need to have a enclose case for that rccb too
any recommendation


and also planning to replace the elcb for the WH to mcb + rccb
just buy 3 way DB that fit + 20A MCB + ABB F202 RCCB 25A 10mA will do right
need to make sure technician use 4mm2 cable during installation too ?
