Cat6A compatibility with UK power lines
Cat6A compatibility with UK power lines
I'm dealing with a home rewiring project and want to install Ethernet throughout every room. The current setup lacks Ethernet cabling, making the installation expensive. People usually ask if Ethernet can be placed near power lines for short distances, but often they're interested in UTP cables. Could I run S/FTP alongside power cables, close to or above them, considering UK power is 240V? Would the S/FTP perform well with minimal interference? Unfortunately, I haven't found any videos showing how far or close cables can be from power before problems arise. Still, I'm here to help. If running Ethernet parallel to power lines is possible, would a Cat6A cable suffice, or should I consider higher-quality options like U/FTP or better?
The cables should be connected to ground at one end, which depends on the switch in use. UTP wouldn't be suitable if they're near AC wiring because that's what STP is meant for. Regardless, it's not the best approach. In commercial setups, they typically use two separate cable channels—one for AC and another for data—to keep them apart while still working together.
I’d choose what a local certified electrician would do. Make sure everything meets the standards in your area. You don’t want an issue later and your insurance won’t cover it because it didn’t follow the rules. Do DIY if you’re avoiding high-voltage wires. By the way, if you need any other conduit for coax or central ventilation, those are good alternatives. Also, remember that more insulation on Ethernet cables makes them less flexible. Besides, they’re heavier and bulkier, which could be a problem if you’re running them in tight spaces.
I've run numerous network tests at work. I think you'll face more issues with accessible cables than disruptions from power affecting data transfers when using S/FTP. The shielding makes a big difference. At home, I keep network cables tied to the power cable next to my PC and don’t see any changes.
