When nonpower-limited fire cables are run in the same raceway as high-voltage wiring, they must be run _____.

The requirement for running nonpower-limited fire cables alongside high-voltage wiring is primarily dictated by safety and regulatory standards, specifically the National Electrical Code (NEC®). The NEC sets forth guidelines that ensure electrical installations minimize the risk of fire hazards and electrical interference between different types of cables.

When nonpower-limited fire cables are placed in the same raceway as high-voltage wiring, adherence to NEC regulations is crucial. These regulations detail how cables should be installed together to prevent issues such as electromagnetic interference that could affect the performance of the fire cables, as well as to ensure the overall safety of the installation. Compliance with NEC regulations means that installers must consider factors like cable types, installation methods, and physical separations necessary to maintain safety standards in electrical wiring.

While other choices may represent considerations in electrical design, they do not encapsulate the comprehensive requirements and legal standards mandated by NEC, making compliance with these regulations the most appropriate response for the scenario described.
