Mystery cables

Could they have inadvertently damage a couple of cables and rather than remove them, simply cut them off and put new ones in their place, but forgot to cut of the other ends? Brian

If he knows the position in the loft where they start, I'd imagine one could follow them from there. Brian

When wiring up cat 5 one tends to pull loads of cables through all over the place because that's quicker than buggering around counting them

They can then be terminated or not depending on what the customer wants at that time. Terminating at one end only probably means that that job was given to an apprentice whoo just terminated everything in sight, again that is cheaper than checking there is a socket at the far end.

Ask yourself what you would do, it you were pulling cables through and a at a given point one jammed and wouldn't pull any further? You would leave that one and pull another one.....

And then, because you hadn't labelled them, terminate the lot anyway and scarper.

That strikes me as possible but perhaps somewhat unlikely.

I'd like to think better of the installer than that, but yes, as Brian suggested above, that is a possibility.

Its pretty much standard practice to run a pair of cables everywhere, even if you don't expect to need em both. The wire is cheap compared to the effort.

Recommend any makes?

Interesting, thanks, though it doesn't explain the lack of labelling. I haven't had a chance to check as yet.

Why label something that goes nowhere?

It may be my OCD, but I'd label it, at least N/C, if not more specific.

Because if John's theory is correct, it does go somewhere - it just isn't connected when it gets there.

Normally I would label even if not being used immediately. Or sometimes label with "orange pair damaged" or similar if the cable did not test ok. That way you know it can be used as a voice pair of for 100MBps ethernet but not gig etc.

Yes, I would have thought that would be the usual practice. Thanks, John.
