Can fiber optic cables be used to run electrical wires
"The answer is yes, they can — but only when certain safety and technical guidelines are followed. " "Fiber optic cables are different from copper wires. They transmit light, not electrical signals, which means they are completely immune to electromagnetic interference, or EMI. Electrical Interference: Electrical cables can produce electromagnetic. I'm not going to pretend to know all the nuisances of the code but it appears it may be ok if the fiber optic cable is ran with the current carrying conductors when they are associated. Are they associated in your case? I don't think drilling a hole in the LB fitting was a smart move. 770 references sections in Chapter 2 and Art. My original plan was to trench new conduit and run CAT8, but given that the existing run is all "customer side" and installed by the former.
