QUOTE(babie @ Oct 22 2014, 09:58 AM) anyone know where to get a rccb auto recloser that can be set to 10 minutes or more? Usually I will prefer manual reset ELCB, as when ELCB trips, it show something wrong. Is better to make sure all appliance are intact before reset. This is for safety. |

QUOTE(keyz @ Jun 14 2015, 11:09 AM) I bump this thread because I have similar problem & sharing the info might give benefit to others. When you have your ELCB tripped, you need to start do some basic troubleshooting.I made a research & I came across suggestion to use less sensitive RCCB. To use RCCB with "HI" type - i.e. High Immunity. So..I bought one from forumer here, brand HAGER. Installed in Nov 2014. As this year, no thunderstorm observed. Only 2 days back I considered very significant & can cause my RCCB to trip using the previous type. I can conclude it does it job very well, as designed to do so.  And not directly changing it to less sensitive type. What if you really have an appliance that having problem? |

QUOTE(keyz @ Jun 14 2015, 12:46 PM) Troubleshooting already done. Disconnect all electrical appliances & observe still tripping. So, no electrical appliance problem. Them call electrician to check. He verified all connection & safety protection, earth cable in good shape. He said in one area, not all house will trip at the same time. As electrician he observe similar case. Details explained to me but I don't understand. Interesting. But how long you stay in this house?BTW, there's something we never do all the time, which is taking out that outdoor rod and have a check on it  Like last time I work in O&G company, they have schedule to to a test on the copper rod.

QUOTE(wodenus @ Jun 14 2015, 01:06 PM) Don't you have to dig it out or something? If it is something needs to be done, it has to be done. Doing some dirty digging works is tedious or getting a house burnt down is tedious? |
