Hello! You were given well-intentioned, but ultimately misleading advice. Passthrough 8P8Cs (aka RJ45s) are fine for PoE, assuming the cable to plug fitment is correct AND the conductors are fully flush cut properly and not shorting. The issue is not really related to PoE but plug fitment in general. There have been anecdotal horror stories, but all can be traced back to poor plug fitment as opposed to passthrough vs push-in. You are unlikely to have a fire hazard, regardless. More likely would be PoE switch port or endpoint device damage, but that applies to much older *passive PoE* where PoE is present on the run even if the device does not request it. Some older Ubiquiti PoE hardware worked that way, as I recall. These days, it's all 802.3af/at/bt, and the device has to request power before it gets it. If you have shorted conductors, the endpoint device and PoE switch cannot even establish proper communication, and PoE injection would not take place.
At least one end of the shielded channel must be grounded for the shield to operate properly. Grounding both ends creates a more robust system, but only if both ends are bonded to the same ground system. If they are not, as in the case of separate buildings using two different ground systems, a condition known as a "ground loop" will result. In such a case, grounding at both ends should be avoided. Also, grounding at both ends is sometimes unfeasible, as in the cases where a channel terminates to an ungrounded device or a terminated end is mounted to a plastic wall plate.
Hello MC Times! Thanks for your comment. Licensed installer or not, we welcome anyone willing to learn and are happy you decided to watch it. Please let us know if you have any questions.
Hello! No, the copper fabric strips are not required. If you wish to go the more traditional route simply fold back the cable shield and wrap the drain wire around it to bond your connection hardware. That said, the traditional method adds quite a bit of thickness and requires not accidentally slicing the fragile cable shield throughout the cable stripping process. The copper fabric strip alleviates many headaches associated with the older process!
Thank you. Too good!
That's what we are here for! Thank you!
Thisbhas helped a ton. Doing good work here.
Glad we could help! Let us know if you ever have any questions, we are always here to help!
Thank you! Very helpful.
Happy to help!
If using for a POE, are pass thrus ok?
I was told they can be a fire hazard vs traditional push in..

Should both terminals be grounded? Is double grounding permitted?

Nice video
Thanks! We definitely try.
Definitely not a licensed installer watching this video.
