cable problems

[potatoman]

Hi ,how do you check the resistance of a cable thats about 140m long, goes through 3 consumer units and between the consumer units it is different sizes

How about answering the question

Its probably easier to Zs test at each db reduction point and compare the the results with the max Zs for each OPD.

How about answering the question

how about learning to be a spark..

I am no spark,but at least I know it,just spent 10k on a solar PV system ,the so called trained electrician never checked the AC cable like what has been sugested and now it does not work and all he wants to do now is increase the paramiters of the inverter

 

[Knobhead]

Leave it to him then. I take it the installation is guaranteed?

How about getting him to provide a test certificate for the job done. For the 10k paid, I think it should be expected.

I must be missing something here. The cable from the PV system is 140m long and passes through 3 CUs and changes CSA?

Exactly what you should be asking your electrician, not coming on to an electricians forum and demanding it from us. All of us here love to help when we can, if we think it is appropriate. In this case, you need to talk to your electrician, not get advice on how to put yourself in danger.

could post a diagram of the cable route showing the 3 consumer units and the sizes of cable on route,(you could draw it as a single line with 3 boxes on it)
