What is the minimum wire size for a multiple-line SPD?

Explanation:
Sizing the wires that connect a multiple-line SPD focuses on ensuring the path can safely carry surge currents and keep impedance at a level that lets the protection work effectively. For a multiple-line SPD, the interconnecting conductors must be at least 6 AWG to provide enough current-carrying capacity and a durable, low-impedance path to the device. Using thinner conductors would limit the surge current the SPD can divert and can lead to overheating during a surge, undermining protection. On the other hand, using a larger size, such as 4 AWG, would work but isn’t necessary and adds unnecessary cost and stiffness. So, 6 AWG is the minimum that meets the requirement.
