So, what should be done if the reading is above 0.35 ohm? Should we contact the DNO? Would this make MCB's operating devices inoperable?

I never realised there were 3 different types of AM2. When I did mine back in day, it was just called AM2. Could somebody tell me the difference between the other 2 different types of AM2?

@gkbailey540 Жыл бұрын

AM2 is done by people who have done the electrical route not via an apprenticeship AM2s is for apprentices AM2E is for experienced workers, so they must have worked in the electrical industry for 5 years to be able to do the AM2E

3 pole or 4 pole main switch at the DB on a 3 phase installation...worth a discussion in a future video?

Must be 4 pole unless you have a very specific reason for a 3 pole.

The earthing conductor itself also wouldn't normally be secured with security bits... It will have a label saying don't remove though... There's only so far you can go to keep the terminally stupid stealing oxygen...

With all this pressure for only skilled people carying out live tests our professional spark who makes final connections doesn't look to be very familiar with basic initial verification stuff. Sure he should be doing this work? Makes me wonder how many new installs initial verification he skipped?😂

FAILED. You didn't zero your leads out first... Saying that I'm a Fluke man so not sure if your test gear has 4 wire compensation. With fluke you zero every time Espicaly when doing Ze, PSC, EFLI and every little ohm matters..... I now wait for a scolding about not knowing my test equipment, lol

@Ten_Pence 2 жыл бұрын

you don't null leads on a zs or ze test its not a low ohm reading..

@glenwoofit 2 жыл бұрын

@@Ten_Pence Its vitally important on Ze, Zs, PSC to zero your leads as your measuring less than an Ohm for Ze also the reading given during the zeroing will tell you about the condition of your leads. And the connections they are making. Many times I've zeroed the leads and found the zero reading high compared to previous times and I've found I've needed to remedy that before I do the test. If your testing in the hundreds or thousands of Ohms 0.4 Ohm lead resistance doesn't matter but that would make your TNC-S reading 0.75 Ohms therefore you'd think the Ze was too high... I Zero my leads Every time I change the test. And I think that was a common sense requirment on my 2391 Test.
