hi, my house had power trip recently and it blows some lights and fan. So i suspected faulty main board which houses the ELCB and MCB. But when i compare mine and images from google, it looks different. Can anyone tell me what's that in the middle, between ELCB and MCB, labeled c32? and how come mine doesn't have main switch? Is there something wrong here?  found on google » Click to show Spoiler - click again to hide... «

The terms aren't correct, should be :
MCCB = Moulded Case Circuit Breaker MCB = Miniature Circuit Breaker C32 is 32A MCB and it act as main switch and provide overload protection. The MCB will trip if your house usage is over 32A. It is also protected against earth leakage with the ELCB. |

Your main board is fine.
The blowing problem is because the TNB side got faulty high voltage coming in. Your main board can't protect the high voltage incoming. This post has been edited by ozak: Oct 8 2014, 02:09 PM |
