Hi all,

house basher working with a local contractor in Galway. Currently waiting to be called for my final phase. Was googling testing and verification as i havent done much of it in recent years, and came upon this site. Most lads I call havent a clue how to do these tests. Hoping to find good info/advice here. Cheers all.

RECI have a Guide to Testing and Verification which is very good and has lots of illustrations.

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 =)

Make sure all protective devices are switched on (apart from main isolator or switch fuse if the DSO (ESB) supply is present, and surge protectors removed. The link should be upstream of any RCDs.
