What is the minimum separation in inches required between supply service drops of max 750 volts and communications service drops?

The minimum separation required between supply service drops with a maximum voltage of 750 volts and communications service drops is established to prevent electrical interference and ensure safety compliance in installations. A separation of 12 inches is specified to reduce the risk of electrical disturbances affecting communication systems, which often operate at lower voltages and are sensitive to interference.

This distance is significant because it helps maintain the integrity of the communication signals and reduces the likelihood of induced voltages that could disrupt service or pose a safety hazard. The National Electrical Code (NEC) and various local codes often dictate these standards to ensure that electrical systems are installed safely and effectively.
