Why You Should Double-Check an Electrician’s Network Cabling Work
When it comes to network cabling, never assume that a job is done correctly just because it "looks" complete. In this video, I demonstrate how easily mistakes can slip through even on seemingly functional ports. I show two active network ports that are live and passing traffic—but strangely, I can’t trace them back to any label or position on the patch panel. This kind of oversight might not break your network immediately, but it creates confusion and delays when future troubleshooting or upgrades are needed.
Even more concerning, I uncover a wall jack that was not punched down properly. At first glance, everything appeared fine, but a closer inspection revealed a poor termination that have resulted in connectivity issues. These errors are often overlooked when electricians—who may not specialize in data networking—handle the cabling. Their focus may be on routing and installing cable, not on validating terminations or ensuring end-to-end continuity.
That’s why it’s critical to verify all cabling work after the electrician finishes. Use tools like a cable tester or certifier, map each port to the patch panel, and inspect each termination. I’ve been asking for photos, a video call and walk thru. Don’t wait for problems to arise down the road—check it while access is still easy and expectations are fresh. A few minutes of validation today can save hours of troubleshooting tomorrow.
