Coaxial cables must not be run in conduits with which type of conductors?

Coaxial cables are specifically designed to carry radio frequency signals and are commonly used in applications like television and internet data transmission. When considering the installation of coaxial cables within conduits, it is crucial to understand the compatibility of various types of conductors.

Running coaxial cables alongside electric light and power conductors can pose significant risks due to the electromagnetic interference (EMI) generated by the high voltage and current in those conductors. This interference can adversely affect the performance of the coaxial cables, leading to signal degradation, increased noise, and potential data loss. The NEC (National Electrical Code) recognizes these concerns and provides guidelines to ensure that different types of conductors are appropriately separated to maintain the integrity of signals transmitted through coaxial cables.

By prohibiting the running of coaxial cables in the same conduit as electric light and power conductors, the code aims to prevent issues related to EMI, thereby ensuring both safety and optimal performance of the communication systems leveraging coaxial cabling. This separation is a critical practice in electrical installation and wiring to avoid complications arising from the interaction of various electrical signals.
