2 k ohm between L+E on lighting circiut

[james king]

sorry? i dont understand? u can change the settings on the megger to low ohms? how do u do tht il try it tomoro

No, don't try it, get someone competent at testing & inspecting to test the circuit while you observe, this is basic stuff but it must be done correctly BEFORE you energise this circuit!!!!!

huh il try changing the setting while the van on the way to site lol i like playing with things lol im not testing any circuit my boss wouldnt let me yet i was only asking

 

[james king]

and im a lil confused about why u would want to do that as you already have it set Mohms and the lowest reading should be 1? so why go lower?

lol.................!

 

[james king]

can some one explain ??

can some one explain ??

I read the second page first and was confused,to get a better understanding, I then read the first page second, and it got worse


I would make a comment,thats if I knew what it was I am supposed to be commenting on

why do a IR test on Kohms

is it to a faint short? but not quite a short?

sorry guys, didnt explain enough.

Upon completion of a 1 floor lighting installation, i decided to do a small test on the circiut before energizing.

The on a continuity test between L+N...i showed : 2.3 k ohm,....should this be ?? ( i didnt energize untill im fully happy with it)

Why would you want to do a continuity test between L-N?....You should be carrying out an R1R2 test followed by an insulation resistance test.....and why does the OP state you got the reading L-E?

 

[ukpablo]

stop this thread right now?????????????????!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!????????????
Im still in the dark after 3 pages?

 

[daiplayer]

well in a power circuit , you shouldnot have continuity between L+N with all apliances removed ... correct ? ...is this not the case in a lighting circiut?

If continuity exists between conductors where there shouldnt be ...deos this not depict a fault also ?

 

[derek preece]

I assume you did an IR test between L+N, need to make sure all the lamps are removed, and the resistance should be greater than 1Mohm, anything less would suggest a fault.

 

[daiplayer]

thankyou !!!

jiga. i think you need to learn the basics. how to differentiate between insulation resistance ( megohm stuff) and continuity testing ( low ohms stuff ) , study the theory, then accompany a tester who has the time to explain as he goes along. best way of learning is by example.
