What surge protection should be selected for a secondary distribution box
Type 1 handles direct lightning strikes at service entrances, Type 2 protects distribution panels from medium-level surges, while Type 3 safeguards sensitive equipment at point-of-use locations. Surge protectors are categorized into three types (Type 1, Type 2, and Type 3) based on their installation location and protection capability. Even a well‑selected SPD can underperform if wiring is long, looped, or poorly grounded. When engineers choose a surge protective device (SPD), the first thing that stands out in a catalog is often the kA rating. But in real projects, the “best” SPD is not always the one with the highest kA value. The 2023 National Electrical Code (NEC) significantly expanded and clarified requirements for surge-protective devices (SPDs). Understanding where, when, and how SPDs are required. Surge protectors (Surge Protective Devices, SPD) installed in distribution board panels are primarily used to protect electrical equipment from transient voltages (surges or spikes) caused by lightning strikes, power grid fluctuations, or other factors.
