NAPIT Certification Scheme testing for napit assesment!

Bright.Spark · Nov 15, 2010

Hey guys I have my napit assesment in a couple of weeks just wanted some clarification on a few things. Firstly, when doing the efl test do I have to do it for each indervidual circuit or just for my ze then work out the zs by calculation? Secondly when doing the rcd test do I need to perform this for each circuit on the main rcd or just perform it for one circuit for each rcd eg downstairs sockets?sorry I'm just paincing a bit, I'm sure it will be fine. Thanks for your help guys.

Hi Bright spark you are correct in saying you'll be fine.Sounds to me like you know what your doing mate your just panicking. Done mine a few weeks ago guy was very nice. Just test aper normal you would test each circuit on a new installation. You would test Zs on each circuit you wouldnt normally do the calc. you might have show you know how to do the calc. But I am sure it will not be as intense as you think good luck mate

Thanks jmtisme, what questions where you asked? Also did you just do an rcd test for the two main rcds or perform the test on each individual circuit? Oh and finally one more question, did u fill in the test sheet before they arrived and just show them the results you found? Sorry.

RCD test is full test, x 1/2, x1, x5, both 0 & 180, don't forget to test the test button as well. 7 tests in all. once per RCD. not each cct. remember to test continuity on dead circiuts first. then Ze and Zs. be sure to know the relationship Zs+ Ze+ R1+R2 .

A mistype there! Zs=Ze+(R1+R2)
