QUOTE(Hansel @ May 9 2016, 06:40 PM) Just wondering if anybody has found permanent solutions to this problem of simple lightning strikes causing the ELCB to trip ?
....... Seems, the problem was caused by cheapo housing developers installing low-quality RM50 Made-in-Malaysia ELCBs.
Note that accidentally shorting the live, neutral and earth wires will also trip the ELCB, eg when I DIY change or add a 3-pin electrical wall socket. Also if water has entered into the 3-pin plug/socket or electrical appliance while it is active.
Heard of a con-man electrician changing the whole electrical wiring of the house(= costs RM3k) and still could not solve this problem. |

MCA's Lee San Choon = Plotek.! Plotek.!
No one will buy a build-then-sell house if they know the ELCB always trip when lightning happens far away = only good-quality ELCB would have been installed during the building process of such new houses. . |

QUOTE(JLA @ Oct 24 2019, 02:17 PM) we dont used ELCB since 20 years ago. If your house still using ELCB then call your wireman. QUOTE Malaysia
In the latest guidelines for electrical wiring in residential buildings (2008) handbook, the overall residential wiring need to be protected by a residual current device of sensitivity not exceeding 100mA. Additionally, all power sockets need to be protected by a residual current device of sensitivity not exceeding 30mA and all equipment in wet places (water heater, water pump) need to be protected by a residual current device of sensitivity not exceeding 10mA. https://en.wikipedia.org/wiki/Residual-current_device |
