Open circuit's on RFC were not common all them yesterday's, wonder if doing the twist helped that.

Twisted conductors are one the most irritating things especially when doing an EICR

Another one of my hates is fastafix boxes fixed before the wall is plastered

That guy is a bit deluded anyway, MK and quality linked in the same sentence

6" of twisted together cpc sharing a sleeve.?

So some walleh can save himself 3 quid a year in sleeving.

When I started, the old guys swore that you ought to twist them, only us newbies that had been re-directed by college didn't.

I would twist them if on a job with certain supervisors as I would get a "bol***king" if I didn't!

Never an open ring to be found.

6" of untwisted together CPC sharing a sleeve......................................saves 3 quid a year as well!!

Back then there wasn't the level of testing we have now

I twist the cpcs together and nowt else.
and some peaple will do this. https://www.google.com/url?sa=t&sou...wwAnoECAUQAg&usg=AOvVaw2fQnV3qJhX1JI5PHvOlgYi

QUITE POSSIBLE ESPECIALLY WITH SOLID CONDUCTORS THHAT AREN'T MEANT TO BE TWISTED TOGETHER PS sorry for shouting

We still did e2e testing on a ring.

I never ever found an open ring if the cables were twisted together, if there was an open point it was always where they weren't twisted together.

You may have found a high resistance socket outlet due to a missing or lose screw, but the ring itself was always still good.

I wouldn't twist conductors together these days, but actually don't see it as a problem if they are (unless you are trying to split it!)

How come? They look better that way as you get a nice flush surface to screw the socket to. Especially if flat plate or something. Must admit though I prefer to nog out and metal ko box.

I can only think it’s because if you need to take them out it damages the wall? Or maybe because if they haven’t been cut in nice and tight they move and take the plaster out? You definitely don’t want them in there loose.

We certainly did, I also agree with your comments.

What testing. The "Megger" only came out when we did pyro. Long time ago though.

It's bad enough having metal boxes with plaster slopped in them without having a fastafix box slopped with plaster
And as you mentioned if it ever has to be replaced you end up with a mess to patch

simple - just leave a live cable end sticking out the box. soon keep the sloppers metal trowel away.

On a recent EICR, I have found an open circuit CPC ring continuity (at a socket) when the two conductors were placed in one piece of sleeving, but only one end made it into the terminal. On installation, likely it tested good. Over some 30+ years, the conductors separated in the sleeving enough to be open circuit. Actually took a while to spot, as the first time I looked, at first glance it looked good, the second CPC just missed being secured by the screw.

Edit: I should add, this was an EICR where I was completing remedials at the same time, to be satisfactory, by agreement with a letting agent.

That's why I usually push the two cps's into the chuck of my cordless... that way you can get a really tight twist... no bu88er is ever getting those fellas apart !!
