What is the minimum required separation between network communication cables and power cables?

The minimum required separation between network communication cables and power cables is 4 inches to reduce the risk of electromagnetic interference (EMI) that can occur when these two types of cables are in close proximity. This separation helps ensure the integrity and performance of the data transmitted over network cables is maintained, as power cables can introduce noise into the network communication signals.

This requirement is based on safety and performance standards, such as those outlined in the National Electrical Code (NEC) and other regulatory guidelines that emphasize maintaining signal quality and reducing potential interference. By adhering to this separation guideline, electricians and installers can help avoid issues with data transmission that may arise from intersecting electrical fields, thus ensuring the reliability of network communications.
