That’s a little weird that it’s happening on a molded patch cable, but somehow water is getting onto the cable and pooling at the RJ45 PoE port.
You can see the arcing is happening primarily at pins 6, 7, & 8 Is it possible these installs were done with the older Ubiquity cable that rots in the sun?

We've had a couple rainstorms out here in Califirnia. Nothing too bad. A little windy... But anyways, i have come across about 6 customers who have a fried/burnt cat5e connector that is plugged into the PoE port of the UBNT injector. Has happened on cabling with and without the ESD drain wire, has happened both on gel-filled and non gel-filled cable, Has happened while plugged directly in wall power and on surge protectors. Has happened on Rockets and Nanostations. However, all were using the UBNT 24VDC/1A PoE injectors. Any ideas? Thanks, Mike
