Wow. Right friendly bunch. Thanks all. Will be due to do it in January. Out of the lads I know that I called, they themselves never do the testing. They bang out the houses and a few other lads that work for the same firm come along after and do it all. 8 of out 10 ive asked havent a clue how to use the megger, the remainder I wouldnt know personally, are impossible to get a hold of. Most tell me theres nothing to it, yet dont know how to do the tests.
I guess its like everything, when you are doing something every day, its second nature. Ive never had to do the tests before, but the crowd we work for now want everything anymore. I can do most of the tests. But im not sure if I am doing them 100% correctly.
Example...Insulation resistance. I kill the power, disconnect the main incoming neutral, link the main incoming feed to the met and do the test at 500v. But on every test ive done I get the exact same result. >500 mega ohms. On rewires and old installations....surely it cant be the same everytime. I have seen a few other record sheets for similar jobs and lads jist make up values, as we know that the min acceptable is 1mega ohm. Although low, should be checked into is still acceptable. So im thinkin 500 is way outta the park. I must be doing it wrong. Anyway, long rant. Thanks again for the friendly welcome =)
