anyone else can comment on these?

Hi,ScottyUK, It is possible that water entering the circuits??The situation is after the tripping during rainny day, the ELCB is reseted the next day and all is functioning properly again. If what u have mean that the water entered the circuits /junction box and make the ELCB to trip, the water...

arcflash99, It's plant on a dry sandy place.i think the soil compact is not a problem. Thanks anyway.

ScottyUK, Sorry that i'm not familiar with the TT earthing arrangement.So, can u give more detail on how to check the TT earthing arrangement in order to solve the problem?And what readings should be obtained in earth tester to make sure the earthing arrangement is in good situation? Very much...

Hi, everyone. It is measured that the earth resistance for a particular grounding is more than 20 ohm.In fact,the earth resistance is required to be less than 5 ohm.Instead of planting a new earth chamber into it, it is any other solution to lower down the earth resistance?Is it a practical way...

I have a question that u might think it's silly.But how i know whether the conductors inside fiber is acceptable by code to be included with power conductors or not?Any reference can be made to justify it?

ok.Now i know this.Thanks for your valuable comments.

Hi,everybody. It is known that the data cable is not advisable to share the same conduit/trench with the power cable to avoid any unnecessary data transmission interference. As i know, fiber optic cable is also a data transmission cable.So, is there any problem if fiber optic cable share the...

First of all, any short-cut way or fastest solution to trace out which circuit cause the problem?Visual check is a hard work because the outgoing circuit is buried underground and there are many outgoing cirucits. Thanks.

hold6448,can u list out an example showing the calculation method?

Thanks for your valuable comments.i'll check it out.

There is a problem that the ELCB is tripped very frequently especially in the heavy raining day.Can someone please explain the cause of this tripping and any procedure/ step to trace out the causes of the problem? Thanks for giving your comments.
