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?
