What should be ensured when using marking string or chalk lines for LP system layout?

When using marking string or chalk lines for the layout of a lightning protection (LP) system, ensuring that conductor runs are straight is crucial. Straight conductor runs help maintain the integrity of the lightning protection system by reducing potential points of failure. Curved or excessively bent conductors can create areas of increased resistance, which may impact the performance of the system during a lightning event.

Straight runs enable a more efficient and direct path for lightning to follow, minimizing the likelihood of inducing harmful voltages in nearby structures or systems. Furthermore, having a clear, straight layout facilitates easier installation and maintenance of the components, ensuring that they can operate effectively over time.

In this context, while flexibility, permanence of marking, and visibility from all angles are considerations for marking systems, they do not directly impact the performance and reliability of the lightning protection layout as much as maintaining straight conductor runs does.
