How much can you flex those tails before they fail ? They seem kind of fragile, and I always worry about moving them.
Being solid copper, they don't tend to like being moved about too much and I would avoid it as much as possible.
The other thing about the actual cable end/pot arrangement, is the fact that if not fitted properly in the first place, they can work loose over the years.
This can make opening a live board the same as opening a jack-in-the-box.
Safety glasses and Hot gloves are standard equipment when I work on any MIMS cabling.
No need to worry about explosiions in this case though, if it's going to occur, it will happen in the first 2-3 years of the cable being in service. [Linked Image]
BTW, Pyro is a lot "safer" as far as cables entering a switch-board panel go, they have a proper gland on them to screw them to the panel hole.
Not like some idiots running PVC through a metal panel without even as much as a bush!. [Linked Image]
Pyro is also quite rugged in it's construction Kiwi, I wouldn't be too concerned about moving it, unless you intend to have a full-on wrestle with it. [Linked Image]
It's made to be moved about once it's installed.
Yes and by the way, the only cable you are allowed to run (vertically) through a lift shaft is Pyro.
NZECP 33 (now defunct I think) although brief, gives some guidance on Pyro installation and cable ratings.
Paul,
I agree totally and to a certain extent the people that write these books, although well-intentioned, have a lot to answer for, considering that the lack of information on older wiring systems, is often where the problems start for the average DIY'er, when they can't find the correct information, instead of getting a professional electrician in, these people are more likely to guess.

If we're really lucky, the powers that be will stop mucking around with the colour codes for a while and let one system get a foot-hold.
Ragnar,

I don't know what some of my classmates are going to think should they once open a j-box with a mess of black, grey and red wires...
Yeah you're right there, I assume this is a 3 phase circuit, not a single phase one?.
