What is the minimum separation required between supply service drops under 750V when run parallel to communication service drops?

6 inches
12 inches
18 inches
24 inches

The correct answer is: 12 inches

The correct answer indicates that a minimum separation of 12 inches is required between supply service drops under 750V and communication service drops. This requirement is established to prevent potential interference between the electrical and communication systems, ensuring both safety and operational reliability. Maintaining this distance is crucial for minimizing the risk of inductive interference or electrical surges impacting communication lines, which could lead to unwanted noise or service disruptions. This separation also helps to ensure that any maintenance or repair work can be conducted safely without the risk of accidental contact between these different types of drops. In the context of electrical installations, adhering to these codes and standards is vital for meeting regulatory requirements and ensuring a safe working environment for electricians and end-users alike.
