Re: Cat-5e

["David Yeend" <david.yeend@xxxxxxxxx>]

I had Cat5 buried under screed once - it was just laid in place with
no
capping or any other protective measures. Before the screed went down it
all
tested OK. After the screed a number of the links had shorts on them.

Keeping in mind that these had been terminated, tested and the plates
covered the only conclusion I came up with was that the the little sharp
stones in the screed had penetrated the sheaf and the insulation of some of
the inner conductors and somehow made the shorts. It seemed impossible to
me
so I removed the terminations and tested between the conductors with a
multimeter - they were still shorted.

It still seems unlikely but I have no other explanation and in future would
do as suggested - run in conduit for greatest flexibility or at least put
capping over the top.

Regards,

David
