explain yourself then? it seems to me that your only repeating what it says in GN3? and you cant give me an explanation why?

how is it any different when testing line to earth and neutral to earth? its the same as joining them together.............. is it or is it not? the damage is done when you test line to neutral..

but i do? line to neutral would be down if a load is connected, but line to earth would not? my question is why? ---------- Post Auto-Merged at 21:52 ---------- Previous post was made at 21:49 ---------- page 59 dude, does it or does it not say that you can test live conductors to earth...

how would it make a difference? line to earth is still down.... by connecting line to neutral and then testing them to earth it would not make any difference.. out of my depth andy? you dont know me so you cant make that judgment.. just read my testing book, 2391 practical guide by christopher...

you can test line to earth and neutral to earth seperatly as well i thought?

Hi guys, I need some help, im doing a periodic on a building and when carrying out an insulation resistance test line to earth it reads as 0 on every circuit i tested, the circuits have neons and fluorecent fittings connected hence why i did line to earth. its doubtful that every circuit is...

yeah it is, and like you said, it goes back to normal when there is no load. how can i check the impedance of the neutral? the mains cannot be shut down under any circumstances, can only do live tests edit, sorry i didnt realise there was another page of posts after this one..

i'll have to get a clamp meter on the phases next week, i think its something to do with the inbalance. "There are several causes of voltage unbalance. 1) Variations in single phase loading cause the current in the three-phase conductos to be different producing different voltage drops causing...

N-E was 0v,

Hi, today i tested the voltage on a 3 phase board and discovered something unusual, when the boards main switch was closed i tested between L1 and N and had 400v, L2 and N 230v, L3 and N 110v. But when the main switch was open, all of them where at 230v. Could this be something to do with the...

i removed the post, dont want the client sueing me hahaha

does this tester trip out rcd's when testing L-E? also, what size cable can you fit between the prongs? would it fit 16mm tails for example?

would they be able to find out then?

I currently work full time and looking at setting up my own business on the side. I havent got a clue what van to get though, i own an astra sport hatch, so instinctively i've been looking at an astra van. What are your opinions? too small? My concerns are i cannot get a van vault in one, well...
