Day from hell!

[telectrix]

Or someone has managed to swap L & N in a hidden junction box?

Did you do any other check to see if it was really reversed?

As you say, if and open CPC is floating close to L the socket tester might just think that N is the live one as the "odd one out".

checked at a socket. first, voltstick.. lights up on red (L) no reaction on N or E. then the fluke . 246V L-N. 246V L-E. 40V N-E. thinking cpc is floating due to damage caused by the screw in the cable. as it's only a 1.0mm cpc. however, the leg that showed 0.01 meg L-E was dissed.

did any of yous ever have days just after you’ve qualified when your doing a simple job but you encounter a slight wee problem and it just snow balls and you’re close to giving up after it’s done lol! Had one a those days

Days from Hell, looking back are the best days you will have!! You will learn more, remember more, understand more and finally get more confidence from them than you ever will from a hundred easy jobs. Suck them up and learn from them. No one ever started a conversation down the pub with an easy job that went according to plan.

what i can't get my head round is the L-E reverse shown on 2 socket testers a chinese import and a fluke, when clearly the L is to L. N is to N and E is to E. the only thing i can think of is that due to the screw in cable, the 1.0mm cpc has been compromised due to repeated fault currents, gone O/C somewhere down the line and confusing the socket testers.

Did you test voltage at the connections at sockets that flummoxed the plug in tester?
I've had before plug in tester showing L-E reversal...what happened was the fault blew apart the cpc, which in turn welded itself onto the L from the socket. So at socket L-N 230v, N-E 230v, L-E 0v.

The downside of MCB's and the like, folk will flick them back on until they stay on, damaging god knows what in doing so.

Most of my bad days come from putting things right,especially work that some Subbies who are not actually interested in the job
We all make mistakes,the art of that is to make sure You correct them.

think it may be something similar, yet, before I'd found the nail in cable i had several sockets powered off the "good" leg, showing correct polarity. (3 greens on the fluke).
