Cat5e cable insulation and plaster


[link to this post]
 
Question about cat5 cabling: if the cable going into the wall isn't capped with a plastic conduit before being plastered over, will the concrete/plaster degrade/destroy the cable's insulation rendering the cable useless? If so then roughly how long will that take to happen?

Assuming the cable won't be moving where it contacts the plaster/concrete, it should be fine. Heat will degrade cable sheathing over time, but it tend to be in the 10s of years if at all. I did some minor electrical cable replacement in a friend's house and the cable sheathing was falling off, but that was 1930s cabling, which is very old and was of a very different grade of sheathing. I wouldn't worry. smile

Thanks as always. I suspected there wouldn't be a problem but wanted to make sure wink
