Shoutout to the old timer who told me to always pull a ground with my data lines

I was wiring a new office building in Springfield last year, running Cat6 for the network. The specs from the client only called for the data cable, no separate ground. An older electrician I know, Frank, saw my setup and told me point blank, 'You're asking for trouble. Pull an 18 AWG ground wire with every run, even if they don't pay for it.' I thought he was being overly cautious, adding cost and time for no reason. I finished the job to spec. Fast forward three months, and I get a callback. Intermittent network drops, weird equipment resets. After two days of head-scratching, we found it was ground potential differences between racks causing noise on the lines. Had to go back and pull grounds through finished ceilings. Frank was right. It cost me more in callbacks than the wire would have. Has anyone else been burned by skipping the isolated ground for data?

Man, that's rough. Been there with a retrofit job. Client cheaped out on shielded cable for some industrial sensors. Same deal, noise issues for months. Took forever to trace. Sometimes you just gotta eat the cost of the extra wire to save the headache later. Old guys like Frank know.

My buddy had a server room in an old brick warehouse in Toledo. They ran all new fiber and copper but skipped the separate ground like kim963 mentioned. First big thunderstorm that rolled through fried three switches and a router. The insurance report pointed right to ground loops between buildings. He said the repair bill was more than double what the grounding wire would have cost for the whole job.
