I am sure oftentimes we all encountered electrical problems in our household.
 Come share your problems and descriptions here.  Hopefully some members have similar experience and are able to solve it to share their solutions here.  I'll start as I have a problem that makes me wanna pull out my hair in clumps  Sometimes when I switch on my living room air cond power supply switch, the whole house just blackout as the main switchboard jumped  Anyone can help??  |

Only the living room air cond power switch, the rest of the other room air cond power switch no problem wor   This post has been edited by phoenix69: Apr 10 2012, 08:23 PM |

QUOTE(ozak @ Apr 11 2012, 03:14 PM) phoenix69@ you need to tell us more detail your problem. Like which breaker is trip. Elcb or mcb. Happen every time switch on or sometime. What is your aircon hp. 1phase or 3phase. If the mcb trip what is the spec of the mcb. In the fuse box there, there is a blue switch that affect all the house power supply. That one tripped.More detail easy for us to pinpoint the problem. I'll go check later to see what is written there. The thing tripped when I switch on the Living room air cond power supply switch. Air cond not yet even switch on via remote. This occourance happen randomly. 8 times out of 10. Call my electrician via phone and he say Air Cond Unit problem. True or not ??? |

QUOTE(ozak @ Apr 12 2012, 09:06 AM) Main MCB and ELCB both affect the whole house power supply. Why your electrician not coming to check? Who install the aircon? Electrician and Air cond installer diffrent people. Electrician should be coming back to completer some balance job later but when I called him yesterday, he say air cond problem.

Will have to do that, it seems.  When installed no issue. problem only comes later.This post has been edited by phoenix69: Apr 12 2012, 10:20 AM |

QUOTE(stevie8 @ Apr 12 2012, 10:08 AM) 8 out of 10, it cannot be the aircond, the aircond itself that is broken. When the aircond sometimes works it is not the aircond. It could be the wiring. Haiz, dunno where ithe issue is lor. wiring or air cond. It happens randomly. Even on sunny days, but recently there is been a lot of rain. Maybe also can be the rain When was this happened the first time? After installing the aircond? The aircond just installed recently? When is this most often happen? During raining day? If during raining days the wire outside to the compressor shorted as rain water conduct the leakage.This is more so the leakage is not high. If high the MCB should trip instead of the main ELCB(the blue switch) where live touches neutral. ELCB trip when leak to earth happens like live wire touches earth. This lead to another question. What is the rating of the MCB? 10A, 20A, 32A? and do you know whcih one in the first place? Where to see the MCB rating? |
