guys.. need some help..
my new house RCCB always trip during raining.
incomer from TNB goes to this
R,Y,B = 32A,415V and 10kA
looks like SPD but no earthing pole from this one
outgoing goes to RCCB in which the specs is
63A 415V 100mA
im thinking to change the RCCB with good brand such as ABB with same specs.
if the same thing happen i would install new SPD with earthing pole
another thing is my neutral terminal at DB box doesnt jump to earting terminal, i saw some videos and most of it jumped together.

QUOTE(ozak @ Dec 14 2015, 10:39 PM) RCCB is not the problem. It work fine. RCCB is not using earth to trip cause it is not a ELCB. You have 3 choice to reduce the trip. 1) change the RCCB to less sensitive to 300mA or 0.3A. But will delay the trip if any short circuit. 2) Install a surge protector to absorb the surge voltage. It will channel the surge to earth. So your earth rod need to be good. 3) Check the earth rod infront your garden. The checking is in Ohm which less ohm is better. (below 100ohm) on no 3, how to check the ohm on the rod i saw someone said Hager and schneider RCCB equipped by anti-storm protection.. is that true?? Thinking of to change my current RCCB with this one  This post has been edited by gagak_84: Dec 15 2015, 03:59 PM |
