again....sheathing is not classed as insulation....its there to provide a degree of mechanical protection to the insulated cores underneath!!! WELL I NEVER!!! Mind you the trouble is though, by default it insulates the bare cpc ? Even though not designed for that purpose,
as WE ALL KNOW.But does offer a degree of protection against corrosion?
further more you still have not explained why the CPC is not insulated on flat twin....have you... But if it was insulated, it could be used as a 3 core like the flex in this thread?
But as it isn't insulated, and doesn't require insulation as it isn't a live conductor, it can't be used as a live conductor can it?
That reminds me, I'm going to send my fluke multi tester back, there must be something wrong with it, everytime I try to measure volts to earth between live and the pvc sheath of a twin and earth, it displays 0 volts?
But when I measure between the cpc terminal with the cpc of the same cable, it measures a voltage?
Come to think of it, measures a voltage between live and anything with an earth potential? But not on PVC or any other material used for insulating electrical conductors?
I'm going to send it back, I can't believe I paid all that money for it and it has an intermittent fault? Come to think of it, they all have the same fault, every meter and tester I've had has had the same fault for nearly 40 years? I can't understand it?
In fact, the same thing happens when I test for voltage between live and the pvc sheath of an armoured, an FP, a flex, a porcelain pillar, a porcelain sink and bath, a pvc matt on a chacker plate gantry, an insulated enclosure, plastic conduit and trunking, and some other thingys, oh I nearly forgot... and the air?
And I think that's it without taxing my brain.
Maybe you know what could be wrong with my meters?[/QUOTE]
not what you stated at #2
clearly you didn`t...otherwise you would not have made the statement at #2 that you did
again not what you stated at #2....you implied the sheath was classed as insulation....which it isn`t...regardless of any insulating qualities it may have.....
so dont blame the tools...
i havn`t once blamed your test gear....
and you still havn`t answered the (very relevent question) i posed to you at #22 & #27 which was why does the CPC on a flat cable not have any insulation along any of its length?
nearly 40 years in the game....you should know then.....
i suspect you dont....
answer today please
