Unfortunately my experiences in the past 10-15 years have been in places where installers have not done a great job and sometimes public areas have been involved.

Interesting, that's definitely one thing to look for. But I have noticed that sometimes there are _mechanical_ problems, e.g. contacts inside, where wiggling/pushing a bit on the cable makes the socket work, at least while pushed/wiggled. Never mind the case I found recently of poorly installed sockets where the incoming CAT6 was sharply bent as the wallbox was too small for a smooth turn (I think CAT6 minimum radius is 50mm or so). | |||||||||||||||||||
