What does the electric operating code apply to?

The electric operating code is applicable to all personnel engaged in various electrical operations because it provides guidelines and standards that ensure safety and proper procedure across the entire spectrum of electrical work. This includes not just high-voltage lines, but also maintenance, testing, and other operations involving electricity. The code is designed to protect both the workers involved in electrical tasks and the integrity of the electrical systems being handled.

In contrast, the focus of other options is too narrow. The electric operating code is not limited to high-voltage lines, nor is it exclusively applicable to maintenance and testing. Similarly, communication cables, while they involve electrical principles, may not fall under the same operational standards as high-voltage systems. Thus, the comprehensive nature of the electric operating code makes it crucial for all personnel involved in electrical operations, ensuring everyone adheres to the same safety and procedural standards.
