SPD interconnecting leads must be routed in a manner that avoids which of the following?

Routing surge protective device (SPD) interconnecting leads properly is critical for their effective functioning in a lightning protection system. Avoiding long runs, kinks, and sharp bends in these leads ensures that the electrical pathway remains as short and direct as possible.

Long runs can introduce inductance and resistance into the system, which may lead to reduced performance of the SPD. Longer leads can also increase the risk of pick-up from nearby electrical noise or other surges.

Kinks and sharp bends can create points of stress in the wiring, which may lead to physical damage or increased resistance. These bends can also potentially cause reflections of the surge signal, decreasing the effectiveness of the protective device.

By ensuring that interconnecting leads are free from long runs, kinks, and sharp bends, the reliability and efficiency of the lightning protection system are enhanced, promoting better discharge of surge energy and ultimately protecting the connected equipment more effectively.
