What is the largest allowable size for conductors used for lightning protection in watercraft?

The largest allowable size for conductors used for lightning protection in watercraft is determined by safety regulations that aim to ensure effective grounding and protection measures against lightning strikes. The accepted size of 0.033 in.² aligns with industry standards for marine applications, providing a balance between sufficient conductivity and manageability for installation.

Using conductors that meet this size ensures that they can handle the high energy levels associated with lightning strikes, reducing the risk of damage to the vessel and enhancing safety for everyone onboard. The specified size takes into account various factors like the conductivity of materials, the environmental conditions marine vessels are exposed to, and the expected current levels during a lightning event. Therefore, choosing a conductor with this specific cross-sectional area is critical for effective lightning protection in watercraft.
