Cat 6 cabling issues

[Gary Merchant]

Hi. I’m in a new build house and the builders have run cat 6 cable from a number of different rooms to where the master line comes in. They connected the cables to wall plates but didn’t terminate the other ends. I have terminated them myself with RJ45 connectors. When I connected the tester to it I found a short on each cable. A particular (and different pin) is shorted on each cable. One cable has multiple shorts. I cut and re-terminated the ends 3 or 4 times and it’s always the same pins that are shorted.

Does this mean the problem is with the wall plates that the builders connected? Is it unusual for them to have not connected each plate properly?
Any help most appreciated. Thank you.

Thanks I’ll have a look. Is there a particular standard of cable you would expect in a build like this? It doesn’t seem as heavy duty as my patch cables. Just wondered if damaged cables could also cause this problem?

Thanks I’ll get some picture sorted.

When I used my cable tester both the master and the remote were cycling through the numbers and both missing out one particular pin. I read somewhere that indicates a short? Is that right? For example on one cable both the master and remote had 2-8 lighting up but missing 1.

This is what one of the panels looked like. One wire had been cut when they scored the cable and another was hanging off. I cut the cable and re-did. The other panels were like this too. So I cut the cables and punched again on them all.

Cable itself is AWG23 solid core.

One of the cables still has no connection on pin 1 (568B). I did both ends multiple times and the tester has no light for that pin. Any ideas? Thanks again for everyone’s help.
