General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables. This is due to several potential risks and complications that can arise from such an arrangement. 110 (B) (2) I think this can be done, but I also read NEC 303. Electrical Interference: Electrical cables can produce electromagnetic. Can I use the same conduit for both electrical and data cables without causing interference? Running electrical and data cables in the same conduit might seem like a tidy, cost-effective idea but it often leads to signal interference, compliance issues, and expensive headaches down the line. We are going to break down the types of cables you will encounter, how to plan and install them correctly, what the code says, and how to keep your cabling subs from blowing up your schedule. " "Fiber optic cables are different from copper.
