Why are communications cables separated from power conductors except where specifically permitted?
- To limit hazardous energy transfer and interference
- BTo avoid labeling the service
- CTo increase branch-circuit voltage for the special occupancy and condition described
- DTo replace cable listing
Why A is correct
Separation, barriers, and listing rules reduce the chance that power faults energize communications circuits and also support reliable signal performance. Shared routing is allowed only under defined conditions.
