It's certainly not cheap, and it's true that when I last did it copper was much cheaper. However, if one was talking of fairly short runs, it would not break the bank, even today. Even at today's retail prices 10mm or 15mm copper pipe plus 1.0mm² or 1.5mm² T&E works out at about £3 per metre.
As you will have seen, the drum on which that cable resides says "Moisture Resistant MI Cable". I haven't heard of that - anyone know to what extent it is 'moisture resistant'?
Yes, but that's because of the sheathing, and applies to all pyro - I was therefore wondering whether this specific 'mositure resistant' description also relates to open ends?
I recall that years ago, it was something to do with the white powder, and they stated that if the ends were left unterminated, moisture would not set in and a standard length termination, whatever that was could be carried out without having to cut any off, thus eliminating waste.
When the time comes? Is it taking you some time to decide what you are going to say will be the way you'll comply with P1 when you apply for Building Regulations approval for that work in your shed?
'Would'or 'will'? Is there some uncertainty about the application?
Many thanks. That's very interesting - they do, indeed, seem to be claiming that (unlike 'ordinary' MICC) this type is pretty mositure resistant even with unsealed ends. Is much of the pyro around like this, or is most of it the 'ordinary' type?
None whatsoever.
