What does Pole Grade C signify in terms of line length?

Pole Grade C indicates that the line will not be shorter than Grade N but will not be lower than Grade B, positioning it within a specific quality range. This grading system is used to classify poles based on various characteristics, including their structural integrity and suitability for supporting telecommunications and power lines.

In this context, Grade N refers to a certain minimum standard, while Grade B denotes a higher quality. Therefore, Grade C serves as an intermediate standard—that is, it guarantees that the line meets or exceeds the criteria of Grade N but does not suggest it meets all the requirements of Grade B. This classification helps ensure that installations maintain a reliable standard of service while providing flexibility in material selection based on project requirements.
